Here is my question! first gets brainliest the question is in the picture,

8 dimes, 15 quarters

Explanation:

The number of dimes=x

The number of quarters=x+7

So the value of each dime and quarter is 0.10 and 0.25

0.1x+0.25(x+7)=4.55

0.1x+0.25x+1.75=4.55

0.35x+1.75=4.55

0.35x+1.75–1.75=4.55–1.75

0.35x=2.8

0.35x/0.35=2.8/0.35

x=8

So the number of dimes there are is 8.

The number of quarters:

x+7

=8+7

=15

So, the number of dimes and quarters in this order are: 8 and 15.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
