Note: I am not 100% sure that this is the correct way to solve this problem. It is just my best attempt to help.
Keep in mind that every percentage can be made into a decimal. 12% = 0.12 because 12% is also 12/100 as a fraction.
Since a percentage is the original number multiplied by the percent, you can solve this problem by dividing the number given by the percent. Be sure to turn the percent into a decimal to make it easier. Your work should look like this:
12% = 0.12
1,000 / 0.12 = 8,333.33
That is the first step. How you have to finish the problem and find what 88% is. To do this, you can simply multiply 88%, or 0.88, times the answer you get in the first part. Your work should look like this:
88% = 0.88
0.88 * 8,333.33 = 7,333.33
Now to check your work, you can add 7,333.33 and 1,000 to see if it equal the total of 8,333.33
7,333.33 + 1,000 = 8,333.3
Since it is equal, this is your answer.
Answer:
5a(6a-7) = 30a² - 35a
Explanation:
Before we begin, remember the following:
a(b+c) = ab + bc
Now for the given:
Assume that the first question mark is x and that the second question mark is y.
The expression now becomes:
(6a-x) * 5a = ya² - 35a
Distribute the 5a over the bracket and equate it with the right-hand side as follows:
5a(6a) - 5a(x) = ya² - 35a
30a² - 5ax = ya² - 35a
By comparison:
30a² = ya² ..............> This means that y = 30
-5ax = -35a
-5x = -35
5x = 35
x = 35/5
x = 7
Based on the above, the expression is:
5a * (6a-7) = 30a² - 35a
Hope this helps :)
Answer:
40 + 4x
Step-by-step explanation:
formula for perimeter:
( length * 2 )+(width * 2)
you know that the length and width will be increased by the same number so you can call that X.
((length + x)*2) + ((width + x) * 2)
then substitute length and width
((15+x)*2) + ((5+x)*2))
you can simplify this a bit more
30 + 2x + 10 + 2x
40 +4x
Goodluck with your schoolwork/homework!
