It is 3/2 • 3/4 because you have to make the mixed number an improper fraction. Theb you would solve 3/2 • 3/4 and get 9/8 and that simplified is 1 1/8
Answer:
11 hours babysitting
7 hours music lesson
Step-by-step explanation:
(11*5) + (7*12) = 139
1/15 because you add all the blocks together and it gives you 15 and there is only 1 blue block so it will be a 1/15 chance of getting it
So first, we multiply out the brackets.
-15x - 18 + 2 = 17 + 16x -1
Then, bring all the terms onto one side so you can solve.
-15x-18+2-17-16x+1=0
Then, we simplify this.
-31x-32=0
Then, isolate x
-31x=32
x=32/-31 or -1.03 (nearest hundredth )
