41. speed = distance ÷ time.
Step-by-step explanation:
33. 10a-2=28
10a=28+2
10a=30
10a/10=30/10
a=3
34. 10a-2=3
10a=3+2
10a=5
10a/10=5/10
a=5/10
lowest term a=1/5
35. 5a+15=40
5a=40-15
5a=25
5a/5=25/5
a=5
36. 2a+10=110
2a=110-10
2a=100
2a/2=100/2
a=50
37. 5÷a=25
25-5=a
a=20
38. 4a+2=14
4a=14-2
4a=12
4a/4=12/4
a=3
hope it'll help
