Answer:

The answer is 60/100 = 45/x !

Step-by-step explanation:

60 percent is the part; 100 percent is the whole. 45 is the part and x, the unknown, is the whole. These numbers make a proportion: 60 is to 100 as 45 is to x.

Help me solve for z, step by step if you can

zheka24 [161]

Answer:

z=6

Step-by-step explanation:

z/3 + 1/2 = 5/2

Subtract 1/2 from each side

z/3 + 1/2-1/2 = 5/2-1/2

z/3 = 4/2

z/3 =2

Multiply each side by 3

z/3*3 = 2*3

z = 6
