Answer:
45% decrease
Step-by-step explanation:
The formula for percent of decrease/ increase is
Original - change/ original
So 40 - 22 = 18
18/40 = 0.45
Turn 0.45 to percent by moving the decimal two spaces to the right
45%
You can check by multiplying the original number by the percentage. So,
40 x 0.45 = 18

The answer is option 3.
Step-by-step explanation:
The area of triangle formula is A = 1/2×base×height. Then substitute the following values into the formula :
Let base = 10,
Let height = 12,
Step-by-step explanation:
We have 3(x + 3) = 10 + 2(x - y).
=> 3x + 9 = 10 + 2x - y
=> x = 1 - y
=> y = 1 - x.
