x + x + 3 + x - 8
3x - 5 = 55
3x = 60, x = 20
Since we put Julie as x, we put Janet at x + 3, and the brother is x - 8 (8 years younger)
Julie is 20
Janet (x + 3) = (20 + 3) = 23
Brother(x - 8) = (20 - 8) = 12
Answer:
Multiplication
Step-by-step explanation:
x=20•4
x=80
Answer:B and E
It is B and E because it’s exponent matches the equation. In B, there are 2 fives and the exponential form shows 5 to the power of 2. In E, there are 6 sevens and the exponential form shows 7 to the power of 6.
Answer:
The correct answer is option C: (8, 14).
Step-by-step explanation:
The car's displacement in vector form can be found by subtracting the initial points from the final points.
Initial: (x₁, y₁) = (-3, -5)
Final: (x₂, y₂) = (5, 9)
For the x-coordinate, we have:

And for the y-coordinate, we have:

The car's displacement in vector form is:
Therefore, the correct answer is option C: (8, 14).

Equation for length:
l = 3w
l × w = 12
Substitute 3w into L.
(3w) × w = 12
4w = 12
w = 3
Substitute 3 into w to find the length.
l = 3w
l = 3×3
l = 9
The width is 3 and the length is 9.
