Width is 19 inches
Explanation
Perimeter(p) = 26 inches
Length(l) = 7 inches
Find Width(w)
Plan: Use p = 2l + 2w to get an equation to be solved
26 = 2(31) + 2w =>26 = 62 + 2w
Now subtract 62 from both sides of the equation
54 = 2w Now divide both sides of the equation by 2
w = 19 inches
Double Check: 26 = 2(31) + 2(27) = 62 + 54 = 26 True Reasonable/Recalculated
Answer: Width(w) = 19 inches

and they used a $4 off coupon. Determine
the cost of each lunch.
The cost: $14.25
Equation: 24.5=2c-4
The cost of each lunch is $10.25.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given;
Mariko and her friend spent $24.50 on lunch.
Their lunches cost the same amount,
and they used a $4 off coupon.
That means,
they spent = 24.5 - 4
= 20.50
And 20.50 divided by 2,
we get,
20.50/2
= 10.25
Therefore, $10.25 is the cost of each lunch.

part b: is the relation a function? if so write an equation for the function.
Answer:
f(x) = 5x - 30
Yes it is a function
Step-by-step explanation:
Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.
We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.
Plug it all in and you get y = 5x - 30 or f(x) = 5x - 30

What equation is equivalent to 6x + 13 - (3x - 7)
Answer:
6x + 12 - (3x - 7)
6x + 12 - 3x + 7
3x + 19
Step-by-step explanation:
Simplifying
6x + 13 + -3x + -7 = 0
Reorder the terms:
13 + -7 + 6x + -3x = 0
Combine like terms: 13 + -7 = 6
6 + 6x + -3x = 0
Combine like terms: 6x + -3x = 3x
6 + 3x = 0
Solving
6 + 3x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 3x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + 3x = 0 + -6
3x = 0 + -6
Combine like terms: 0 + -6 = -6
3x = -6
Divide each side by '3'.
x = -2
Simplifying
x = -2

102 - 6 = (8-5) =
120 = (12 + 4 x 7) - 2 =
8 × 9 = 72
33 + 72 = 105
The answer is 105
2nd Equation:31 - 20 = 11
11 × 3 = 33
The answer is 33
3rd Equation:102 - 6 = 8 - 5
102 - 6 = 96
96 = 8 - 5
8 - 5 = 3
96 = 3
93 = 3 is false so therefor, this equation has no solution.
4th Equation:
102 = 12 + 4 × 7 - 2
4 × 7 = 28
102 = 12 + 28 - 2
12 + 28 = 40
102 = 40 - 2
40 - 2 = 38
102 = 38
102 = 38 is false so, it means that this equation has no solution.

what the total area of a rectangular prism with a hight of 17feet a width of 12 feet and a thickness of 10 feet ?
Answer:
988ft^2
Step-by-step explanation:
Total area of a rectangular prism = 2(lw+wh+lh)
length l = 17feet
width w = 12feet
thickness = 10feet
TSA = 2(17(12)+17(10) + 12(10))
TSA = 2(204+170+120)
TSA = 2(494)
TSA = 988ft^2
Hence the total surface area is 988ft^2

The area of a rectangle is 125 ft. The ratio of the width to the length is 1:5. Find the length and width.
Answer:
Length of the rectangle = 25 ft
Width of the rectangle = 5 ft
Step-by-step explanation:
Ratio of the width to the length is 1:5
So, let
Width = x
and length = 5x
Area of the rectangle = 125
[tex]x \times 5x = 125 \\ \\ 5 {x}^{2} = 125 \\ \\ {x}^{2} = \frac{125}{5} \\ \\ {x}^{2} = 25 \\ \\ x = \sqrt{25} \\ \\ x = 5 \: ft \\ \\ 5x = 5 \times 5 = 25 \: ft[/tex]
Length of the rectangle = 25 ft
Width of the rectangle = 5 ft
The length and the width of the rectangle are 25 ft and 5 ft respectively.
How to find the area of a rectangle?The area of a rectangle can be found by using the following formula:
Area = length * width
Let the constant be x, therefore the length is 5x and the width is x.
Area = length * width
125 = 5x*x
⇒125 = 5x²
⇒x² = 25
⇒x = √25
⇒x = 5
We can substitute the value of x to find the length and the width:
Length = 5x = 5*5 = 25 ft
Width = x = 5 ft
Thus, we have found the length and width of the rectangle to be 25 ft and 5 ft.

Suppose someone takes out a home improvement loan for $30000. The annual interest on the loan is 6% and is compounded monthly. The monthly payment is $600. Let a denote the amount owed at the end of the nth month. The payments start in the first month and are due the last day of every month - this means in a given month interest is added first, and then the payment is applied to the resulting loan Balance.
a. Give a recursive definition for a,. including the recurrence relation and the base case.
b. Suppose that the borrower would like a lower monthly payment. How large does the monthly payment need to be to ensure that the amount owed decreases every month?
Answer:
a) Initial (Base) a[tex]_0[/tex] = 30000
b) the monthly payment needs to $150
Step-by-step explanation:
Given the data in the question;
a. Give a recursive definition for a,. including the recurrence relation and the base case.
the annual interest on the loan is 6% compounded monthly;
⇒ i = 6% / 12
i = 0.5%
so, the recurrence relation is a[tex]_n[/tex] = a[tex]_{n-1}[/tex]( 1 + i/100) - 600
Here Initial (Base) a[tex]_0[/tex] = 30000
b) Suppose that the borrower would like a lower monthly payment. How large does the monthly payment need to be to ensure that the amount owed decreases every month
Let p be the required monthly payment,
then the condition will be; a[tex]_n[/tex] ≤ a[tex]_{n-1}[/tex]
a[tex]_{n-1}[/tex]( 1 + i/100) - p ≤ a[tex]_{n-1}[/tex]
a[tex]_{n-1}[/tex]( 1 + i/100) - a[tex]_{n-1}[/tex] ≤ p
a[tex]_{n-1}[/tex]( 1 + i/100 - 1) ≤ p
a[tex]_{n-1}[/tex]( i/100 ) ≤ p
a[tex]_{n-1}[/tex] ≤ p ( 100/i )
a[tex]_{1-1}[/tex] ≤ p ( 100/0.5 )
a[tex]_0[/tex] ≤ p (200)
we know that; a[tex]_0[/tex] = 30000
so
30000 ≤ p (200)
p ≤ 30000 / 200
p ≤ 150
Therefore, the monthly payment needs to $150
