Mr. cooper is building a playset in his backyard for his kids. he has a made a scale drawing of the playset to him estimate the amounts of building materials he needs to purchase. part of the playset includes a rectangular sandbox, which has a length of 5 1/2 feet and a width of 7 1/2 feet. on the scale drawing, the length of the sandbox is 2 3/4
a. the scale used in the drawing is = 1 foot.
b. on the scale drawing, the width of the sandbox is inches.
c. if mr. cooper decides to make a new scale drawing of the playset, in which he uses a scale of 1/4 inch = 1 foot, all of the dimensions in the old drawing will be multiplied by a factor of

B.On the scale drawing, the width of the sandbox is 2.8 inches.

Can i please get brainliest.

Step-by-step explanation:

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
