  one solution: h = 3

Step-by-step explanation:

The coefficients of h on either side of the equal sign are different, so there is one solution. (If they were the same, there might be 0 or infinite solutions.)

  2(h +1) = 5h -7 . . . . given

  2h +2 = 5h -7 . . . . eliminate parentheses

  9 = 3h . . . . . . . . . . add 7-2h

  3 = h . . . . . . . . . . . divide by 3

The solution is h = 3.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
