Answer:
8 animal balloons
Step-by-step explanation:
Using equivalent ratios, or a proportion, you can solve for the number of animal balloons that clown can create in 6 minutes:
Now, set the simplified ratio equal to the time of 6 minutes and the variable of 'b' to equal the number of balloons:

To get equivalent fractions, the numerator and denominator must be multiplied by the same factor:

8 animal balloons in 6 minutes
15=-4+z/3
+4 +15 = +4 -4 +z/3
cancels the 4 on the right side
19 = z/3
3 x 19 = z/3 x 3
cancels 3 on the right side
I think the answer is z = 57
Answer:
AB = 142
Step-by-step explanation:
If M is the midpoint, then AM = MB
6x+5 = 7x -6
Subtract 6x from each side
6x-6x+5 = 7x-6x -6
5 = x-6
Add 6 to each side
5+6 = x-6+6
11=x
We want to find AB
AB = 6x+5+7x-6
AB = 13x -1
= 13(11) -1
=143-1
= 142
