In step one, you are supposed to add 25 to both sides, because if you just subtract, it would be -5x-50=53
Answer:
13
Step-by-step explanation:
This triangle appears to be 5 units wide and 12 units tall.
Using the pythagorean theorem, a^2 + b^2 = c^2, we get 25 + 144 = 169 or 13^2.
Therefore the answer is 13.
Answer: A
Step-by-step explanation: Because 4 quarts equal a gallon and 4+4 equals 8
Answer:
7.5 quarts is equal to 7.098 liters
Explanation:
multiply the value in quarts by the conversion factor '0.946352946'. So, 7.5 quarts = 7.5 × 0.946352946 = 7.097647095 liters.
F(x) = 112 - kx
f(-3) = 121
f(-3) = 112 - k(-3)
f(-3) = 112 + 3k
121 = 112 + 3k
121 - 112 = 3k
9 = 3k
9/3 = k
3 = k <===
