Addition and subtraction equations. Solve and check each equation. 1. M + 42 = 952. D - 23.8 = 105.93. 85 = 7.4 + f + 10.24. A + 9 + 60.4 = 1085. 43 + h = 9386. N - $32 = $82

Respuesta :

1.

M + 42 = 95

M=95-42

M=53

2.

D - 23.8 = 105.9

D=105.9+23.8

D=129.7

3.

85 = 7.4 + f + 10.2

85-7.4-10.2=f

85-17.6=f

f=85-17.6

f=67.4

4.

A + 9 + 60.4 = 108

A=108-60.4-9

A=38.6

5.

43 + h = 938

h=938-43

h=895

6.

N - $32 = $82

N=82-32

N=$50
