Answer:
m/10 + 4.7 = 3.7
Step-by-step explanation:
Given m = −10.
put the value of m = -10 in this equation
a) 5m + 5 = −40
5(-10) + 5 = -40
-50 + 5 = -40
-45 = -40
b) −42 + 3m = 72
-42 + 3(-10) = 72
-42 - 30 = 72
-72 = 72
c) m/2 + 21 = 15
(-10)/2 + 21 = 15
-5 + 21 = 15
16 = 15
d) m/10 + 4.7 = 3.7
-10/10 + 4.7 = 3.7
-1 + 4.7 = 3.7
3.7 = 3.7
