Step-by-step explanation:
you just divide
Step-by-step explanation:
100-15=85%
85% × 29.99
=$25.49
Answer:
40%
Explanation:
To find the percent decrease, use the formula
% decrease = (amount of decrease)/(original amount)
The amount of decrease in the pumpkin is
6.5 - 3.9 = 2.6
The original amount is 6.5.
This gives us 2.6/6.5 = 0.4 = 40%
You have to distribute it or use FOIL (if u know that method). This is basically factoring.
for instance:
(2x-9)×(x+4)
first: 2x × x = 2x^2
second: 2x × 4 = 8x
third: -9 × x = -9x
forth: -9 × 4 = -36
now combine like terms.
2x^2 + 8x -9x - 36
(8x and -9x are like terms)
(add the two together, which is -1x or -x)
2x^2 -x -36 is ur answer
now do this same method for the rest
