A=h7
divide both sides by h
A\7=h
use equation A(t) = a(1+r)^t to solve. you want to find the starting so solve for A
1000 = a(1+.03)^5
1000 = 1.1592740743a
a = $862.61
Answer:
Step-by-step explanation:

Hey there! I'm happy to help!
First, let's multiply the numerators. We will put q+5 in parentheses so we can multiply it by 4q.
4q(q+5)
We use the distributive property to undo the parentheses.
First, we multiply 4q by q.
4q×q=4q²
And we multiply 4q and 5.
4q×5=20q
So, our numerator right now is 4q²+20q.
Now, for the denominators.
2(q+4)
We do 2 by q.
2×q=2q
And 2×4, which is 8.
So, our denominator is 2q+8.
Right now, our fraction is
, and this is your correct answer. However, we can simplify it a bit more. We can divide the 4 by 2, q² by q, and simplify the 20 and the 8.
4/2=2
q²/q=q
20/8=5/2
Now, our final product is (2q+5)/2
But, mark down your answer as
because that is technically correct.
Have a wonderful day! :D
Distance = Rate x time
Time = 4.5 hours
Rate = 70 miles per hour
Distance = 70 x 4.5 = 315 miles.
