3x - (2x + 8) = -6
3x -2x - 8 = -6
x - 8 = -6
x - 8 + 8 = -6 + 8
x = 2
We wish to know how much faster Grant rows than Arianna.
d=G-A and we want our answer is miles/hour so
d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)
d=10mph-6mph
d=4mph
So Grant rows 4 miles per hour faster than Arianna.
Answer:
i can answer 2, you divide each side by the same number as many times as you can. learned that in middle school I think
2x=360/4
2x=90
divide by 2 on each side
x=45
Answer:
the balance in the account after 20 years is $819
Step-by-step explanation:
The computation of the balance in the account after 20 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $500 × (1 + 2.5%)^20
= $500 × 1.025^20
= $819
Hence, the balance in the account after 20 years is $819
