Answer:

40%

Step-by-step explanation:

percent change in Mike's long distance runs = (change in miles ran / initial longest mile ran) x 100

change in miles ran = new personal record - initial personal record

14 - 10 = 4

(4/10) x 100 = 40%

Five cats each ate 1/5 of canned food and 1/5 cup of dry food. How much food did they eat altogether?
rewona [7]

Answer:

2

Step-by-step explanation:

With regards to the above, we can sum up the foods ate together by the 5 cats, then we have;

= 1/5 + 1/5

= 2/5

Then we can multiply the value above by the 5 cats

= 2/5 × 5

= 10/5

= 2

The cats eat 2 foods together.

An Easter basket contains eggs of three different colors. Find the total number of eggs in the basket if 2 7 of all eggs are gre
mrs_skeptik [129]

Answer:

Total number of eggs in basket = 56

Step-by-step explanation:

Let z be the total number of eggs

Green eggs = \frac{2}{7} × z   ........1

Blue eggs =  \frac{1}{4} × z    .......2

Rest of eggs = 26  ........3

The addition of 1, 2 and 3 is equal to z  

\frac{2}{7} × z + \frac{1}{4} + 26 = z

\frac{8z + 7 z}{28} + 26 = z                        ∵GCF for 4 and 7 is 28  

\frac{15z}{28}  + 26 = z

15z + (26 × 28) = 28z                ∵ multiply both sides by 28

15z + 728 = 28z

28z - 15z = 728     .......... rearranging above equation

13z = 728  ⇒   z = \frac{728}{13}   ⇒  z = 56

Total number of eggs = z = 56
