Answer: Kathryn has 23 super bouncy balls left
Step-by-step explanation:
first you need to subtract 35 by 12. you can do this by doing 5 minus 2 which is 3 and 3 minus 1 which is 2 then you add 2 and 3 together and get 23.
4. D
12/15 isn't the same as 30/40. 12/15=0.8, while 30/40=0.75. All the other options are equal.
5. C
Of course, you could figure this out by plugging in all the answers, and seeing which ones make the two sides equal, however, cross multiplying (multiplying the top of one fraction with the bottom of the other fraction) would be much faster. This will be your equation: 8*46=18*n. After combining like terms and dividing, you should find that n=20.
6. A
This problem is basically the same as #5. Cross multiplying so the equation you get will be 0.6*1.2=1.6*w. W should be 0.45.
Hope this helps!!

Answer:
= 50.6 miles per hour
Showing Work:
This is a fraction equal to

We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 8
405 miles ÷ 8
8 hours ÷ 8
=
