Answer: 5 days

Step-by-step explanation:

so we need to find:

55 - 6a = 40 - 3a

with a being the days we need to find

Solve the equation -3 = 8x - 4yfor y
Anestetic [448]

You would add 4y to both sides of the equation which would leave you with

4y - 3 = 8x

then you would divide the entire equation by 4 leaving you with

y - 3/4 = 2x

then you would add 3/4 to both sides of the equation leaving you with

y = 2x + 3/4

Consider the reduction of the rectangle. A larger rectangle has a length of 18 inches and width of 8 inches. A smaller rectangle
Ne4ueva [31]

Answer:

18/8 = x/3

x = 6.75 inches (length)

Step-by-step explanation:

Hi, to answer this question we have to write 2 ratios using the information given:

A larger rectangle has a length of 18 inches and width of 8 inches.

Inches /width = 18/8

So, for a rectangle that has a length of x inches and width of 3 inches the ratio is :

x/3

Solving for x:

18/8 = x/3

18/8 (3) =x

6.75 in= x
