solve by elimination x-5y=35 and 3x-6y=51
Answer: x=5 y=-6
(5,-6)
Step-by-step explanation:
Solve by elimination
[tex]\begin{bmatrix}x-5y=35\\ 3x-6y=51\end{bmatrix}[/tex]
multiply x-5y=35 by 3
= 3x-15y=105
[tex]\begin{bmatrix}3x-15y=105\\ 3x-6y=51\end{bmatrix}[/tex]
[tex]3x-6y=51[/tex]
-[tex]\underline{3x-15y=105}[/tex]
[tex]9y=-54[/tex]
divide 9 on both sides
y= -6
Now solve for x
you must plug in -6 for y in either equations
i plugged in -6 for y in 3x-15y=105
[tex]3x-15\left(-6\right)=105[/tex]
[tex]3x+15\cdot \:6=105[/tex]
[tex]15\cdot \:6=90[/tex]
[tex]3x+90=105[/tex]
subtract 90 on both sides
[tex]3x=15[/tex]
[tex]\frac{3x}{3}=\frac{15}{3}[/tex]
[tex]x=5[/tex]

Answer:
x=5
y= -6
Step-by-step explanation:
equ= equation
x - 5y= 35 ----- equ (1)
3x - 6y= 51 ----- equ (2)
Multiply equ (1) by 3
3x - 15y= 105 ----- equ(3)
3x - 6y= 51 ----- equ(4)
Subtract equ(4) from equ(3)
-9y= 54
y= -6
Substitute value of y into equ(1)

Answer:
86
Step-by-step explanation:
The sum of the angles in a quadrilateral is 360 degrees
since EF is parallel to HG
m < E + m< H =180
y + 10 + 2y -31 =180
-21+ 3y= 180
3y = 180 + 21
3y = 201
y=67
m <E = 67 + 10 =77
m < F = 2*67 -40= 134 -40=94
m < H = 2*67-31 = 134 -31 = 103
m < G = 360 - (m<E+ m < F + m < H)
= 360 - ( 77+94+103)
= 360- 274
=86

A park ranger sees a fire from an observation deck 120 feet high. The fire is at an angle of
depression 2.5 degrees. How far is the fire from base of the observation deck ?
Answer: 2748.5 feet
Step-by-step explanation:
Given that the
Height h = 120 feet.
angle of depression = 2.5 degrees
The angle of depression is equal to the angle of elevation.
The base of the observation deck will be achieved by using trigonometry ratio.
Tan Ø = opposite/ adjacent
Opposite = height = 120 feet
Adjacent = base = ?
Substitutes the given parameters into the trigonometry ratio.
Tan 2.5 = 120 / adjacent
Adjacent = 120 / tan 2.5
Adjacent = 2748.452
Therefore, the base of the observation deck is 2748.5 feet

Answer:
Equation y = -2x -3
Step-by-step explanation:
(1,-1) (3,-5)
Slope = -5-(-1) / 3-1 = -5+1/2 = -4/2 = -2
y = mx + K
-1 = -2(1) + k
-1 = -2 + k
k = 1
Equation y = -2x+1
Answer:
Step-by-step explanation:
slope=(y2-y1)/(x2-x1)=(-5-(-1))/(3-1)=(-5+1)/2=-4/2=-2
y-y1=m(x-x1)
y-(-1)=-2(x-1)
y+1=-2(x-1)
y+1=-2x+2
y=-2x+2-1
y=-2x+1
Walter lost his favorite book. He used the map below to discover that he is currently at point (1, 6). He determined that his book is 5 units either to the west or south of his current location. Which of these could be the location of the book? (-4, 6) (1, -1) (-4, 1) (6, 6) (6, -4) (1, 1)
Answer:
(-4, 6)
Step-by-step explanation:
If his book was 5 units to the west, it would be at (1 - 5, 6) = (-4, 6) and if it was 5 units to the south it would be at (1, 6 - 5) = (1, 1). Therefore, (-4, 6) is the answer because (1, 1) isn't an answer choice.

2nd: (-2,0). Simply put the called and check.
Answer:
Question 1 Answer: consistent, dependent; infinite
Question 2 Answer: (2, -2) y= 2 - 2x
Step-by-step explanation:
Question 1 explanation: Solve the first equation for y.
3 = 4x + y
3 − 4x = y Subtract 4x from both sides.
y = 3 − 4x Rewrite the equation.
Simplify the second equation by dividing.
2y = 6 − 8x
y = 3 − 4x Divide both sides of the second equation by 2.
Rewrite the system.
y = 3 − 4x
y = 3 − 4x
The number of pizzas sold in one weekend at Pete's Pizzas is shown. Pie chart of pizza sales. Data includes 130 hamburger, 175 pepperoni, 60 cheese, and 35 veggies.
a) If Pete's sales remain consistent, how many pepperoni pizzas will he have sold when the total number of pizzas sold reaches 1600?
b) How would the circle graph be different if Pete had sold 200 pepperoni pizzas, 100 hamburger pizzas, 50 veggie pizzas, and 50 cheese pizzas?
Answer:
a) 560
b) The Hamburger section will become smaller, the pepperoni will get bigger, the veggie pizza area would increase and the cheese section will decrease.
Step-by-step explanation:
a) 400 pizzas were originally sold (add all pizzas)
1600/400=4
Therefore, 175 (pepperoni pizzas) *4 = 560.
b) Find the difference between the original amount compared to the new amounts to determine what will happen to the size of each sector.

A veterinarian will prescribe an antibiotic to a dog based on its weight. The effective dosage of the antibiotic is given by d ≥ 1∕5w2, where d is dosage in milligrams and w is the dog's weight in pounds. Which of the following ordered pairs gives an effective dosage of antibiotics for a 35-pound dog?
Answer:
B) (35, 260)
Step-by-step explanation:
A veterinarian will prescribe an antibiotic to a dog based on its weight. The effective dosage of the antibiotic is given by d ≥ 1∕5w2, where d is dosage in milligrams and w is the dog's weight in pounds. Which of the following ordered pairs gives an effective dosage of antibiotics for a 35-pound dog?
A) (35, 240)
B) (35, 260)
C) (260, 35)
D) (240, 35)
Ordered pairs is composed of pairs, usually an x coordinate and a y coordinate. It refers to a location of a point on the coordinate. It matches numbers to functions or relations.
Given the relation between d is dosage in milligrams and w is the dog's weight in pounds as d ≥ 1∕5w²
For a 35 pound dog (i.e w = 35 pound). The dosage is given as:
d ≥ 1∕5(35)² ≥ 245 milligrams.
For an ordered pair (x, y), x is the independent variable (input) and y is the dependent variable (output).
The dog weight is the independent variable and the dosage is the dependent variable.
From the ordered pairs, the best option is (35, 260) because 260 ≥ 240
Answer:
(35, 260)

Which expression can be used to find the surface area of the following triangular prism? And stop reporting my question!
Answer:
S.A=132
Step-by-step explanation:
A=[[tex]\frac{1}{2}[/tex] x b x h]2
A=[tex]\frac{1}{2}[/tex] x 4 x 3 x 2 12+50+40+30=132
A=12 cm²
A=L x W
A=10 x 5=50
A=L X W
A=10 X 4=40
A=L X W
A=10 X 3=30
Each triangular end has a surface area of (1/2)(base)(height), which in this case is (1/2)(4)(3), or 6 units^2. There are two ends, so the total area of the ends is 12 units^2. The three remaining sides account for the surface area
(4)(10) + (5)(10) + 3(10). or 120.
The sum of the surface areas of all five areas is 120 + 12 units^2, or 132 units^2
.Answer:
132 units^2

hope this helps
Answer:
C is the most reasonable.
Step-by-step explanation:
So we can put it in a ratio of 4:3:1. Then add all those up and do 240/8 which is 30. So each number in the ratio is 30. Then we do 4*30=120. 3*30=90. 1*30=30. Both red and blue are close to there answers but red is closer.
You are going to a movie, and your friend says it is showing some time on the weekend between noon and 8, but won't say when, exactly.What are the chances itis playing on Sunday between 6 and 8?
Answer:
The chances are 1/6 because 6-8 is 1/6 of the possible timings.
:)
Answer:
7/8
Step-by-step explanation:
Because it is 8 hours combined (noon to 8) 8 will be the denominator and since it is 3 hours (6 to 8) 3 is the numerator. Keep that aside.
Since there are 2 days in a weekend 2 will be the denominator and since it is on Sunday 1 will be the numerator.

Which expression can be used to find the surface area of the following square pyramid?
Answer:
4[1/2(5 x 6)] + 6x6
Step-by-step explanation:
The first part of the expression is 4[1/2(5 x 6)]. This is the formula to find the surface area of the triangles. A regular triangle's area is 1/2(l*w). Since there are four trinagles, you have to multiply the whole expression by 4.
The second part of the equation is finding the surface area of the base which is a square. Since squares have four equal sides, its safe to say that you can use 6 * 6.

Which is a correct step to solve the equation 1=−4+3/8x
A.4(1)=4(−4+3/8x)
B.1=8(−4+3/8x)
C.8(1)=8(−4+3/8x)
D.3(1)=3(−4+3/8x
Can someone please help me
Answer:
C. 8(1)=8(−4+3/8x)
Step-by-step explanation:
Given equation
1=−4+3/8x
in this equation in denominator we have 8x,
since we are solving for x we cannot eliminate it, but we have to eliminate 8 in denominator, so that there only numerator in equation and solving process becomes easier.
To eliminate 8,we need to multiply both side by 8, so as to balance the equation and also 8 from denominator gets cancelled in RHS.
1=−4+3/8x
multiply both side by 8
8(1)=8(−4+3/8x)
Thus, option c is correct one
8(1)=8(−4+3/8x)
solving it
8 = -32 + 3/x
adding both side 32
8+32 = -32 + 3/x -32
=> 40 = 3/x
=> x = 3/40
