Answer:
5- -1= -6
Step-by-step explanation:
think of it as being in debt, you owe someone 1 dollar than you borrowed 5 more dollars from them now you owe them 6 dollars, that's what subtracting negatives are like.
what is 314.16 rounded to the nearest hundredth
Since there is no number in the thousandths place which would make the number in the hundredths place round up or down, we keep the number the same:
314.16

To go to the park, It costs $4 plus $3 per child. Which equation shows this situation
where x represents the number of children
Answer:
y = 3x + 4
Step-by-step explanation:
Because $4 is your base pay, it is your y-intercept. And because it is $3 per child, then that is your slope. "x" represents how many objects/people/etc. there could be.
how can I solve this equation, 6x + 3y = -12, as y=mx+b?
Answer:
y=-2x-4
Step-by-step explanation:
6x + 3y=-12 subtract 6x to other side
3y=-12-6x divide 3 to every number
1y=-4-2x

Answer:
only Katie is right
Step-by-step explanation:
first, find the nth rule using the equation n = a + (n - 1)d
a = first term (here, it's 22)
n = the position of a term
d = the constant difference between each term (here, it's -5 since each term reduces by 5)
put these in and then simplify:
n = a + (n - 1)d
n = 22 + (n - 1)(-5)
n = 22 - 5n + 5
n = -5n + 27
this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!
Answer: Only Katie
Reason: Only Katie is correct!
Help plz it’s a test quest-
A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for fencing. He knows that the area of
the yard is 51 square meters and that the width is 5.2 meters longer than the length. Which equation could be solved to determine the
dimensions of the backyard, where the length is / and the width is w?
0=w/2+5.2w -51
0=/2+5.2/-51
4w +10.451
4/+10.4 = 51
Answer:
0=w^2-5.2w-51
Step-by-step explanation:
51=width x length
length=width-5.2
substitute for length
51=width x (width-5.2)
51=w^2-5.2w
0=w^2-5.2w-51

Answer:
Step-by-step explanation:
4). Surface area of front and back = 2(lengh × height)
= 2(7×3)
= 63 cm²
Surface area of top and bottom = 2(length × width)
= 2(8×7)
= 112 cm²
Surface area of left and right = 2(width × height)
= 2(8×3)
= 48 cm²
Total surface area = 63 + 112 + 48
= 223 cm²
5). Surface area of top and bottom = 2πr²
= 2π(4)²
= 32π
= 100.53 cm²
Surface area of middle = h(π × d)
= 4(π × 8)
= 32π
= 100.53 cm²
Total surface area = 32π + 32π
= 64π
= 201.06 cm²
6). Surface area of front and back = [tex]2[\frac{1}{2}(\text{Base})(\text{Height)}][/tex]
= Base × Height
= 6 × 8
= 48 cm²
Surface area of bottom = 6 × 11
= 66 cm²
Surface area of the left = 8 × 11
= 88 cm²
Surface area of right = 10 × 11
= 110 cm²
Total surface area = 48 + 66 + 88 + 110
= 312 cm²

Answer:
10b - 60
Step-by-step explanation:
So the question is asking to use the Distributive Property with giving the equation 10(b - 6).
So the distributive property is just multiplying the number outside the parenthesis with the numbers inside the parenthesis, so lets implement that :
(10 * b - 6 * 10)
10b - 60
Answer:
The answer is 6
Step-by-step explanation:
10(b - 6) =
10 x b = 10b
10 x 6 = 60
10b = 60
10/10 10/60
= 6

please help i have no clue
Answer:
Step-by-step explanation:
Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24

The supplement of an angle has a measure that is three times the angle. Write and solve an equation to find the measure of the angle and the measure of its supplement.
Answer:
3a + b = 180
Step-by-step explanation:
Supplementary angles are angles that, when added, equal 180 degrees.
Let's use a to represent the unknown angle, and b to represent its supplement:
3a + b = 180
How can i identify a slope
Answer:
Rise over Run.
Step-by-step explanation:
If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

Evaluate acb−(a+d) if a=−2 , b=3 , c=−12 , and d=−4 .
Answer:
78Explanation:
acb − (a + d)
a = -2b = 3c = -12d = -4= (-2) (-12) (3) - (-2 + -4)
Parenthesis: (-2 + -4) = -6
= (-2) (-12) (3) - (-6)
Simplify (-2) (-12) (3): 72
72 - (-6)
78if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is acb−(a+d)
a times c times b minus a plus d
The values of a, b, c and d are given.
In the given expression a,b,c and d are variables and plus and minus are operators
a=−2 , b=3 , c=−12 , and d=−4 .
Substitute these values in expression acb−(a+d)
(-2)(-12)(3)-(-2+(-4))
When minus is multiplied two times we get positive, if three times we get negative
72-(-2-4)
72-(-6)
Seventy two plus six
72+6
Seventy eight
78
Hence if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.

Hillside orchard grows Fiji apples and Gala apples. There are 160 Fiji apple trees and 120 Galla apple trees in the orchard. Hillsides Orchers owners decide to plant 30 new gala apple trees. find the number of new Fiji apple trees the owner should plant if they want to maintain the same ratio of Fiji apple trees to gala apple trees
The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.
RatioRatio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
The ratio of Fiji apple to Gala apple = 160 : 120 = 4 : 3
If 30 new gala trees are planted, hence the number of gala trees increases to 150 (120 + 30). To maintain the same ratio:
Number of fiji apple = (4/3) * 150 = 200
New Fiji apple trees = 200 - 160 = 40
The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Write the slope-intercept form of the equation of the line.
through: (4,1), perpendicular to y = -2x + 5
Answer:
y = -10x + 5 and y = 2/5x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
for your first problem, just plug in the m and b values to complete the equation.
1.) y = mx + b ⇒ y = -10x + 5
plug in -10 for x (slope) and 5 for b (y-intercept)
and for the second problem...
since you're given a value for slope as well as a coordinate pair, all you need to do is plug those values into the equation for their respective variables and then solve for b. (it doesn't matter what order you plug values in, but i'm going to fill them in in the order of the equation; y, m, and x)
1.) plug in -1 for y
y = mx + b ⇒ -1 = mx + b
2.) plug in 2/5 for m
-1 = mx + b ⇒ -1 = 2/5x + b
3.) plug in -5 for x
-1 = 2/5x + b ⇒ -1 = 2/5(-5) + b
now it's time to solve for b! start by multiplying 2/5 and -5.
-1 = 2/5(-5) + b ⇒ -1 = -2 + b
add 2 to both sides of the equation. on the right side, it cancels itself out. on the left side, adding 2 to -1 gives you 1.
and you're left with 1 = b! :)
therefore, y = 2/5x + 1
