Answer:
C
Step-by-step explanation:
You take Photographer B's hours and subtract them. 110-80=30. You know that there is an hour between so you can split 30 in half to get 15. Now that you know Photographer B is charging 15 an hour you can take 80 and subtract 15 twice because it cost 80 at 2 hours. You subtract 30 from 80 and you get 50.
No, 2 x 7 is 14 which is even.
There are 9 balloons remaining, of which 4 are yellow. therefore the probability that the next balloon is also yellow is 4/9
1)
34a = 14
a = 14 ÷ 34
a = 7/17
2)
<span>-29 = -32m
-32m = -29
m = 29/32
</span>
