Answer:
7 out of 15 chance of selecting a pink or purple balloon
Step-by-step explanation:
just add the total of the two types of balloons and since there is 15 balloons in all the answer would be 7/15
(3+4)h÷2=10.5
7h÷2=10.5
×2=×2
7h=21
÷7=÷7
h=3
your numbers are -5 and 9, since 9 * -5 = -45 but 9 + (-5) = 9 - 5 = 4
