The answer is C an example is 20% of $20 is 4, so you would lose the zero and double the 2 to get 4
Divide both sides by 2
q = 0.04
21.
So to solve for the value of a variable in an equation, you would need to isolate x on one side. The first thing you have to do is multiply 2 and (x + 7) together, which can be rewritten as 2(x) + 2(7). After multiplying, your equation would be:
, or A.
22.
So the rule with multiplying exponents with the same base is to add the exponents together, and the rule with dividing exponents with the same base is to subtract the exponents. Your equation will be simplified as such:
![4^{(3+4)-9}\\ 4^{7-9}\\ 4^{-2}](https://tex.z-dn.net/?f=%204%5E%7B%283%2B4%29-9%7D%5C%5C%204%5E%7B7-9%7D%5C%5C%204%5E%7B-2%7D%20)
Now the rule with converting negative exponents into fractions is
. In this case, 4^-2 would turn into
, or C, which is your final answer.
Answer:
He should buy 4 boxes
Step-by-step explanation:
25 divided by 8 is 3.125, but you want to have enough so the least amount you can buy is 4.
Answer:
"In word" as in word form?
3/4 = three fourths
1/5 = one fifth
3/4 = three fourths (again?)
1 3/5 = one and three fifths
