Step-by-step explanation:
Step 1: Combine like terms
9x + 6 = 42

9x = 36
Step 3: Isolate x by dividing by 9 on both sides
x = 4
Answer: 55.1°F
Step-by-step explanation:
We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:
= 1.6° × 2
= 3.2°F
If the temperature on the ground is 58.3°F, then the temperature when the plane reaches an altitude of 2,000 ft will be:
= 58.3°F - 3.2°F
= 55.1°F
The balance after ten years is $2,208.04.
When an amount of money is compounded quarterly, it means that the amount deposited and the interest earns interest every quarter. The formula that can be used to determine the balance in 10 years is:
FV = P (1 + r)^nm
- FV = Future value
- P = Present value = $1000
- R = interest rate = 8%/4 = 2%
- m = number of compounding = 4
- N = number of years = 10
$1000 x (1.02)^40 = $2,208.04
