Answer:
x=4 and y=5 commonly notated as (4,5)
Step-by-step explanation:
The equations
Equation 1: 3x+3y=27
Equation 2: x-3y= -11
The second equation looks like it will be the easiest to rearrange.
x-3y = -11
add 3y to each side to get
x = 3y-11
Substitute that in for x in equation 1 so
3x+3y=27
turns into
3(3y-11) +3y =27
multiply out to get
9y-33+3y =27
Condense variables
12y-33=27
add 33 to each side
12y= 60
Divide by 12
y = 5
Plug into one of the original equations (I will be doing both to show it doesn't matter what equation you use, but you only need to use one equation, I personally think it is easier to plug into the second equation)
Equation 1: 3x+3y=27
Plug in what we got for y
3x+3(5)=27
multiply
3x+15=27
subtract 15 from each side
3x=12
divide by 3
x=4
Equation 2: x-3y = -11
Plug in what we got for y
x-3(5) =-11
Multiply
x-15= -11
Add 15 to each side
x=4

s y=x+7
y = 6x + 2
Solution:
How do you solve this
Step-by-step explanation:
y=x+7........eqni
y=6x+2.....eqnii
putting the value of x in eqnii
y=6x+2
or, x+7=6x+2
or, 7-2=6x-x
or 5= 5x
hence,x=1
sbstutuung the value of x in eqni,
y= x+7
=1+7
=8
hence the value of y is 8

Alyssa invested a total of $1500 in two accounts. One account paid 2% annual interest, and the other account paid 4% annual interest. After one year, Alyssa earned a total of $44 interest. How much did she invest in each account? $# in 2% account, $# in 4% account
Answer:
700$ at 2% 800$ at 4%
Step-by-step explanation:
x+y=1500 This is because the total is 1500 dollars into 2 different accounts, x and y.
0.02x+0.04y=44 This is because it says 2 percent interest in one account and 4 percent in the other, and the totals add up to 44 dollars.
Now use elimination method.
x+y=1500(-0.02)=-0.02x+-0.02y=-30
0.02x+0.04y=44
Now you end up with 0.02y=14, solve for y and you get 700. That's the value of y which now you can then subtract from 1500 and get 800 which is the value of x.

how many toothpicks are needed to build the tree on day 100?
Answer:
100 x 4 = 400 - 91 = 309
Step-by-step explanation:
Answer:
100= 4 + 3 (100-1)
4+3 (99)
4 + 297 is 301
Step-by-step explanation:
The first row starts with 4 toothpicks, and they increase by +3 in each row. The first tree is already accounted for which makes the 4 + 3, and why I have 100-1. The teacher said the answer was correct but I doubted the equation. Can you tell me if this is correct?

Decide whether ABCD with vertices A (3,8) B (6,5) C (5,4) , and D (2,7) is a rectangle a rhombus or a square
Given:
The vertices of the quadrilateral ABCD are A(3,8), B(6,5), C(5,4), and D(2,7).
To find:
Whether the given quadrilateral is a rectangle, a rhombus or a square.
Solution:
Distance formula: The distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the side lengths are:
[tex]AB=\sqrt{\left(6-3\right)^2+\left(5-8\right)^2}[/tex]
[tex]AB=\sqrt{\left(3\right)^2+\left(-3\right)^2}[/tex]
[tex]AB=\sqrt{9+9}[/tex]
[tex]AB=\sqrt{18}[/tex]
[tex]AB=3\sqrt{2}[/tex]
Similarly,
[tex]BC=\sqrt{\left(5-6\right)^2+\left(4-5\right)^2}=\sqrt{2}[/tex]
[tex]CD=\sqrt{\left(2-5\right)^2+\left(7-4\right)^2}=3\sqrt{2}[/tex]
[tex]AD=\sqrt{\left(2-3\right)^2+\left(7-8\right)^2}=\sqrt{2}[/tex]
The length of diagonals are:
[tex]AC=\sqrt{\left(5-3\right)^2+\left(4-8\right)^2}=2\sqrt{5}[/tex]
[tex]BD=\sqrt{\left(2-6\right)^2+\left(7-5\right)^2}=2\sqrt{5}[/tex]
From the above calculation, we conclude that the given quadrilateral has two pairs of congruent opposite sides and equal diagonals.
Opposite sides of a rectangle are equal and its diagonals are also equal.
Therefore, the given quadrilateral ABCD is a rectangle.

A company makes 110 bags.
46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
Answer:
51/110
Step-by-step explanation:
No: of bags with buttons but no zips = 46
No: of bags that have both buttons and zipz = 110-(46+20+39) = 5
No: of bags with buttons = 46+ 5 = 51
Total no: of bags = 110
Probabilty = 51/110

Set up and solve a system of equations to solve the problem.
A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of
the coins is $1.30. How many nickels and how many dimes are in the jar?
The jar contains
nickels and
dimes.
9514 1404 393
Answer:
14 nickels6 dimesStep-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.

Calculate the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest.
Use the formula,
P=A(rn)(1+rn)nt(1+rn)nt1
where A is the amount to finance, r is the annual interest rate, n is the number of times interest is compounded in one year, and t is the number of years.
Answer:
352.05
Step-by-step explanation:
I don't know how to interpret the equation you wrote and so I just used annuities
I have attached my work below
the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest is $353.95.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, a $14,790 auto loan over four years at 6.9% annual interest.
To calculate the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest,
we can use the formula for the monthly payment of a loan:
M = P * (r/12) * (1 + r/12)ⁿ / ((1 + r/12)ⁿ¹)
where:
M = monthly payment
P = principal amount (loan amount)
r = annual interest rate (as a decimal)
n = total number of payments (number of years * 12)
Plugging in the given values, we get:
P = $14,790
r = 0.069 (6.9% expressed as a decimal)
n = 4 * 12 = 48 (4 years with 12 payments per year)
M = $14,790 * (0.069/12) * (1 + 0.069/12)⁴⁸ / ((1 + 0.069/12)⁴⁸⁻¹)
M = $353.95
Therefore, the monthly payment for a $14,790 auto loan over four years at 6.9% annual interest is $353.95.

The Area of the given figure is 6 inch²
Step-by-step explanation:
For a given Trapezoid
side a = 1 ½ = 1.5 inch
side b = 2½ = 2.5 inch
height (h) = 3 inch
Now, Area of Trapezoid
Formula:A = ½ (a + b) × h
A = ½ (1.5 + 2.5) × 3 inch
A = ½ × 4 × 3 inch
A = 2 × 3 inch
A = 6 inch²
Thus, The Area of the given figure is 6 inch²
