87.5% of 64 is 0.875 • 64 = 56
Hope this helps.
Let's define x -> Darlene's weight
and
y -> Leah's dog Weight
Equation 1x5y
Equation 2: xty 84
Since x is equal to 5y in Equation 1, you can replace x in the Equation 2 by 5y. So, Equatoin 2 can be written as
5y + y = 8
6y = 84
y = 14
So, you find y is equal to 14 (Leah's dog weight). Then, x is equal to 5y, 5 * 14 70. So, x is equal to 70 (Darlene's dog weight.
HOPE THIS HELPS !
Deceleration is always the opposite of Acceleration so is negative. So deceleration =-2.2m/s^2
Answer:
x = ±4 (x = 4 and x = -4)
Step-by-step explanation:
4x²-16 = x²+32
3x²-16 = 32
3x² = 48
x² = 16
x = ±4
Therefore, x = 4 and x = -4
