Timothy bought groceries two days during the week: • Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday • Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday Which equation models the relationship between the cost of groceries after taxes, and the cost of groceries before taxes?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x

y=120w+200 y intercept
Answer:
w= - 5/3 + 1/120y, y eR
Step-by-step explanation:
y=120w + 200
Move the terms
-120w=200-y
Divide both sides
w= - 5/3 + 1/120y
Write in parametric form
w= - 5/3 + 1/120y, y eR

The dimensions of a rectangular building used to store tools for electrical lineman has a length of 12x+24 feet and the width of 20x-10 feet.
1.Write the expression that represents the area of the building, in terms of x.
2. Write the expression that represents the perimeter of the building, in terms of x.
3. If the perimeter is going to be 220 feet, what are the dimensions of the building.
Answer:
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
Step-by-step explanation:
It is given that:
Length of building = 12x + 24
Width of building = 20x - 10
Area = Length * Width
Area = (12x + 24) * (20x - 10)
Area = 12x(20x - 10) +24(20x-10)
Area = [tex]240x^2-120x+480x-240[/tex]
Area = [tex]240x^2+360x-240 = 2x^2+3x-2[/tex]
Perimeter = 2 (Length + Width )
Perimeter = 2 (12x + 24 + 20x - 10 ) = 2 (32x +14 )
Perimeter = 64x + 28
Putting Perimeter = 220
220 = 64x + 28
64x = 220 - 28
64x = 192
Dividing both sides by 64
x = 3
Length = 12(3) + 24 = 36 + 24 = 60 feet
Width = 20(3) - 10 = 60 - 10 = 50 feet
Therefore,
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet

2y = 4x + 18
-6x + 3y = 27

They result in the same equation
rewrite it:
2y = 4x +18
3y = 6x + 27
divide so that you have only y
y = 2x + 9
y = 2x + 9

what are the first 5 terms of 30-n^2
Answer:
29, 26, 21, 14, 5
Step-by-step explanation:
To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the n th term formula.
30 - 1² = 30 - 1 = 29
30 - 2² = 30 - 4 = 26
30 - 3² = 30 - 9 = 21
30 - 4² = 30 - 16 = 14
30 - 5² = 30 - 25 = 5
The first 5 terms are 29, 26, 21, 14, 5
Reasons why each one of those don't belong

• Show your setup (how would it look on a Balanced Scale?)
• What does X equal?
• Check:
Answer:
X = 12
Step-by-step explanation:
When a number increased by 4
Let that number = x
x + 4
is doubled...
2(x + 4)
the result is the same
=
when the number is increased by 20
x + 20
Find the number
2 (x + 4) = x + 20
2x + 8 = x + 20
2x - x = 20 - 8
x = 12
What does X equal? X equals 12
Check:
Insert the x = 12 into the equation;
2 (x + 4) = x + 20
2 (12 + 4) = 12 + 20
2 (16) = 12 + 20

Draw the graphs of the lines below on the same grid to find the coordinates of the point of
intersection.
y = x
y = 3x - 4
Answer:
(2,2) is the solution of the given lines.
Step-by-step explanation:
Given that,
y = x ..(1)
y = 3x-4 ...(2)
We need to find the coordinates of the point of intersection.
From equation (1) and (2).
x=3x-4
4 = 3x-x
4 = 2x
x = 2
Also,
y = 2
Hence, the coordinates of the point of intersection is (2,2).during a fundraiser ms dowsons class raised $560 which is 25% more than mr caseys class raised. Mr caseys class raised how much money

Answer:
v = $312.5
Step-by-step explanation:
Let
Value of the gem stone = v
Weight of the gemstone = w
v = k * w²
Where,
k = constant of proportionality
w = 4 carat
v = $200
v = k * w²
200 = k * 4²
200 = k * 16
200 = 16k
k = 200/16
k = 12.5
Find v when w = 5 carat
v = k * w²
= 12.5 * 5²
= 12.5 * 25
= 312.5
v = $312.5
