Answer:
X=65°
Step-by-step explanation:
Both angles combined is a right angle as indicated by the small square drawn on it, a right angle is always 90° therefore
(x-15°)+40°=90°
combine like terms
x+25°=90°
subtract 25° from each side
x=65°
Answer:
y=-2x+11
Step-by-step explanation:
Answer:
I don't know if this is correct but wouldn't it be 560?
Step-by-step explanation:
If you have 10 on one side, you divide 10 by 1/4 to get 40. So you need 40 blocks to fill one side, and 3 1/2 on the other only needs 14. 14*40=560.
The rates are not equivalent; 24/6 is less than the rate 36/8.
