Can someone me with problem 4 and also tell me if they think the rest is correct !

k=(-7y+11)/4

Step-by-step explanation:

Given

11(k-1)= 7(k-y)

In order to find the value of K we have to separate k on one side, so

Multiplying 11 and 7 into the brackets on both sides

11k-11=7k-7y

Subtracting 7k on both sides

11k-11-7k=7k-7y-7k

11k-7k-11= -7y

Adding 11 to both sides

4k-11+11= -7y+11

4k= -7y+11

4k=-7y+11

k=(-7y+11)/4

So the value of K is (-7y+11)/4.

a .4y4

hope this !

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
