Let the two numbers be x and y, in which x is larger than y. From these variables, we can formulate the following equations:
x = y + 1 --> eqn 1
x³ - y³ = 631 --> eqn 2
Since there are two unknowns and two independent equations, this system is solvable. Substitute equation 1 to equation 2, then solve for y.
(y + 1)³ - y³ = 631
Solving for y,
y = 14
x = y + 1 = 14 + 1 = 15
<em>Therefore, the two consecutive numbers are 14 and 15.</em>
Answer:
A and B
Step-by-step explanation:
The 11 should be multiplied after 4 + x because the (4 + x) is the total amount of driveways she shoveled. If you solve for x using A's equation, you should get 9 as your answer. Therefore, your answer choices are A and B.
Answer:
I think it should be 5y+24
