Joey's cleaning service charges $50 per week to clean a home. Amy's cleaning service charges $50 per week , plus $25 for cleaning supplies.which equation can be used to express the amount that Amy's cleaning service charges?

A y=50x

B y=50x-25

C y=1/50x

D y=50x + 25

Answers

Answer 1
Answer:

Answer:

D y=50x + 25

Step-by-step explanation:

The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.
Answer 2
Answer:

Answer:

D

Step-by-step explanation:

y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)

That means the equation is y = 50x + 25

Rebecca jogged 1.5 miles in 12 minutes.At that rate, how many minutes will it take her to jog 3.5 miles?

Answers

1.5 = 12

1 = 12/1.5 (8)

3.5 = 8*3.5 = 28 minutes 
1.5 mil - 12min
3.5 mil - x

x= (3.5mil*12min)/(1.5mil) =28min

How to divide 4.50 by 18.00

Answers

Data:

price($)__ gallons
x -------------- 1
18.00 ------------ 4.5

Solving: Rule of three (directly proportional)
(x)/(18.00) = (1)/(4.5)
multiply cross
4.5*x = 18.00*1
4.5x = 18.00
x = (18.00)/(4.5)
\boxed{\boxed{x = \$\:4.00}}\end{array}}\qquad\quad\checkmark

Answer:
The price in dollars per gallon is $ 4.00

Tina is making rectangular signs. Each poster has an area of 1800 square inches and the length is 30 inches more than the width. Find the length and width of her sign. If x represents the width of each sign, select all of the equations that could be used to solve this problem. 2(x)+2(x+30)=1800 (x+30)(x)=1800 x(30x)=1800 x(x+30)=1800 Part 2 Find the dimensions of each rectangular sign. width = inches length = inches

Answers

Let the width be x. Since the length is 30inches longer than the width, the length is 30 + x.
Area = length x width = (30 + x)(x)
i.e. (30 + x)(x) = 1800 square inches.

30x + x^(2) =1800 \n x^(2) +30x-1800=0 \n x^(2) -30x+60x-1800=0 \n ( x^(2) -30x)+(60x-1800)=0 \n x(x-30)+60(x-30)=0 \n (x+60)(x-30)=0
x + 60 = 0 or x - 30 = 0
x = -60 or x = 30
but the width cannot be a negative number, hence x = 30inches
i.e. width = 30 inches
length = 30 + 30 = 60 inches.
