Answer:
x=12
Step-by-step explanation:
Let y equal number of pushups a day. When x = 1, y = 8. When x = 2, y = 10. 10 is a factor of 30. Multiply y by 3. However, since x increases by 1 when y increases by 2, multiply x by 6 (2*3). That equals 12. Therefore, when x = 12, y = 30.
-6
15/4 ÷ -5/8
Copy dot flip
15/4 * -8/5
Rewrite
15/5 * -8/4
3 * -2
Answer: D) Adding heat to the reaction
15m
tan° = opposite/ adjacent
tan45 = 15/x
1 = 15/x
and = 15
