Answer:
-3
Step-by-step explanation:
3s + 4 = -5
3s + 4 - 4 = -5 - 4
3s = -9
3s/3 = -9/3
s = -3
Hope this is right
<u>64 + 69 + 73 + x </u> = 70<u>

</u> x = (70 * 4) - 206
= 280 - 206

Answer:
2h + 10
Step-by-step explanation:
The question gives one the height of Tree A (8h - 1) and the height of Tree B (6h - 11). The problem asks one to find how much taller Tree A is than Tree B. This problem can be modeled using a simple subtraction problem, the height of Tree A, minus the height of Tree B. Remember to distribute the subtraction sign outside of the parenthesis, and only combine like terms;
(Tree A) - (Tree B)
= (8h - 1) - (6h - 11)
= 8h - 1 - 6h + 11
= 2h + 10
Since there was no numerical value given for the variable (h), nor any value which this expression is equal, the final answer is (2h + 10).
