Please help me with these?? Work needs to be shown.

Answer:

Step-by-step explanation:

7) Area = 615.75 sq. km

πr² = 615.75

3.14*r² = 615.75

r² = 615.75/3.14 = 196

r = √196

r = 14 km

8) circumference = 15.71 yards

πd = 15.71

3.14*d = 15.71

d = 15.71/3.14 = 5 yards

9)Area = 415.48 sq.inches

πr² = 415.48

3.14*r² = 415.48

r² = 415.48/3.14 = 132.31

r = √132.31

r = 11.5 inches

diameter = 11.5*2 = 23 inches

Solve 9x−y=45 for y.

Taya2010 [7]

So to solve for y, we need to get y alone on one side of the equation. So we are going to subtract 9x from both sides of the equation to get:

$-y=-9x+45$

And since y is negative, we are going to divide both sides by -1 in order to make the y positive:

$y=9x-45$
