Answer:
x=12, y=-3
Step-by-step explanation:
Plug (-4y) in for x in the top equation. The equation will now read 2(-4y) + 7y = 3. Distribute the 2 into the perenthecies getting: -8y+7y=3. -8+7 is -1 giving -y+3. Divide by -1 making y = -3. Plug -3 back into the top equation and solve for x: 2x + 7(-3)=3. 2x-21=3. 2x=24. x=12.

Answer:
The answer is $79.45
Step-by-step explanation:
If the given 4.5 percent interest rate is a yearly rate then according to the information in the question, we can calculate Bonnie's money at the end of the three year period as:
The initial amount x interest rate x time = 70 x 0.045 x 3 = $9.45
So the amount of money after the three year period comes up to $79.45 for Bonnie.
I hope this answer helps.
D=rt
distance = rate*time
rate=15mph
time=3.5hours
distance = 15*3.5 = 52.5
He will travel 52.5 miles in 3.5 hours assuming his rate does not change.
