Answer:
84%
Step-by-step explanation:
divided and move to the nearest 2 numbers
The solutions to an algebraic equation equal the highest power in that equation. So, in this case, the answer is 23.
2 a + b = 15.7
Since the sides are equal length, the equation is:
2 · 6.3 + b = 15.7
We can solve it:
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
The correct answer is 18696 ft/hour
