Answer:
X=20
Step-by-step explanation:
1/3 and 2/5 --> what we need is a least common denominator
(1/3)x5 (2/5)x3
5/15 and 6/15
so he needs to paint his room two more times which will make the 5/15 become 15/15
you start with 5/15 and you need to add "5/15" two more times which will make 15/15
so you do that to 6/15
6/15+6/15+6/15=18/15=1 3/15 or 1 1/5 cans of paint ANSWER
Answer:
12^2x = 7^4 = 2401
7^2=12^x
We know that a^x * a^x = a^(x+x) or a^2x
Multiply each side by 12^x
7^2 * 12^x=12^x * 12^x
7^2 * 12^x = 12^(x+x)
Replace 12^x with 7^2 on the left hand side since they are equal
7^2 * 7^2 = 12^ (2x)
7^(2+2) = 12^(2x)
7^4 = 12^2x
2401 = 12^2x
Step-by-step explanation:
Solution for what is 200% of 34
34/x=100/200
<span>(34/x)*x=(100/200)*x - </span>we multiply both sides of the equation by x
<span>34=0.5*x - </span>we divide both sides of the equation by (0.5) to get x
<span>34/0.5=x </span>
<span>68=x </span>
x=68
<span>now we have: </span>
<span>200% of 34=68</span>
