Step-by-step explanation:
Eliminate -5 first, then simplify the equation for only one value of x.
<u>Add 5 to both sides:</u>
<u />
<u>Subtract 2x from both sides:</u>
<u />

Answer:
18 years (to the nearest year)
Step-by-step explanation:
<u>Compound interest formula</u>:
where A is amount, P is principal, r is interest rate (decimal format), n is the number of times interest is compounded per unit 't', and t is time
Given:
- A = 4490
- P = 2400
- r = 3.5% = 0.035
- n = 12
Therefore, it would take 18 years (to the nearest year) for the account to reach $4,490
Answer:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Step-by-step explanation:

Step-by-step explanation:
sprints: 1/8 of 74 1/2 = 74.5 divided by 8=9.3125
Hunts: 3/4 of 57 3/4= 57.75 divided by .75=77
9.3125 + 77=86.3125 86.3125 divided by 2= 43.156 mph average speed
