Answer:
x = 5
Step-by-step explanation:
Set up an equation:
x + 19 = 5x - 1
Add 1 to both sides:
x + 20 = 5x
Subtract x from both sides:
20 = 4x
Divide both sides by 4:
x = 5
If i can remember correctly, R = i/pt
p and t are directly related
R and I are directly related
Answer: -9 + 21 = t t = 12°C.
Step-by-step explanation: For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees it will give us our original degrees.
Solve.
-9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12)
12 = t
So, the original degrees in the beginning of the day was 12°C.
The percentage of the golf clubs original price to its new inflated price is: %1.15 more expensive. To find out the percentage, we just need to divide 552 by 480: 552/480 is 1.15. That is our percentage.
