I do this in a different way, but i'll do it in both
Mine:
30 ÷ 2 = 15
4 ÷ 2 = 2
15+2, 15 -2
17, 13
Kristen Has 17
Yours:
h+(h+4)=30
-4 -4
h+h = 26
2h = 26,
h = 13, Back to the equation, use 13 as a sub. for all the h's
13+(13+4) = 30
13 + 17 = 30
Hope this helps!
The most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6.

Answer:
-23/4 =c
Step-by-step explanation:
21+30=-4c+28
Combine like terms
51 = -4c+28
Subtract 28 from each side
51 = -4c+28
Subtract 28 from each side
51-28 = -4c+28-28
23 = -4c
Divide each side by -4
23/-4 = -4c/-4
-23/4 =c
