Answer:
The percentage decrease is 15%.
Step-by-step explanation:
To find the percent decrease of any two numbers, subtract the numbers and divide it by the original.
So in this case:
20-17÷20
= 3÷20
= 0.15
Now convert to a percent.
0.15×100 = 15%
Answer and explanation:
25 x 3 = 75
75 x 2 = 150
I found the product of the first two numbers, then multiplied the third.
The answer is 150. Hope this helps!
Answer: 7 to the 12 power
Step-by-step explanation:
when multiplying the same number with different exponents, all u have to do is add the exponents
For this case, the first thing we must do is define a variable.
We have then:
n: number of days.
We now write the explicit formula that represents the problem.
We have then:
an = 4n + 15
Where,
15: crunches the first day
4: increase the number 4 each day
Answer:
An explicit formula for the number of crunches Abbie will do on day n is:
an = 4n + 15
They lost L games.
They won W games.
W = 2L
W + L = 96, but W = 2L, so
2L + L = 96
3L = 96
L = 32
W = 2L = 2 * 32 = 64
They won 64 games.
