75/100 = 15/20 , divide by 5 . 75/5= 15
100/5= 20 . Divide by 5 for 15/20 . 15/5= 3 , 20/5= 4
3/4*36 - Cross out 4 and 36. Divide by 4
4/4= 1 , 36/4= 9
3*9= 27
Answer :
75% of 27 =36
Question:
Which is equivalent to after it has been simplified completely?
Answer:
Step-by-step explanation:
Given
Required
Simplify
We start by splitting the square root
Replace 180 with 36 * 5
Further split the square roots
Replace power of x; 11 with 10 + 1
From laws of indices;
So, we have
Further split the square roots
From laws of indices;
So, we have
Rearrange Expression
From laws of indices;
So, we have
<em>The expression can no longer be simplified</em>
Hence, is equivalent to
p = 3m
Step-by-step explanation:
p = number of pages
m = minutes read
3 times the number of minutes she reads will give you the number of pages she read.
We want to get x by itself so we combine like terms first.
First subtract 4 from both sides
4+11x=9x+2x
Now add 9x and 2x together
4+11x=11x
Subtract 11 from both sides
4=0
The equation is false.
3/4 = 9/12
2/3 = 8/12
9/12 - 8/12 = 1/12
So Johnny ran for 1/12 of an hour longer than Angie.
