Turn the percentage into a decimal by sliding the decimal twice from the right to the left and multiply it to the number
add/subtract it depending on if it's increasing or decreasing
Answer:
the number is 20
Step-by-step explanation:
6% of x = 20% of 6
0.06x=0.20*6
0.06x=1.20
x=1.20/0.06
x=20
Your answer would be, C 5/45 and 4/36. In simplified form they both equal 1/9, meaning they are a proportion.
1) I'd say 4.44 hours
2) About 2.46 hours
We can use the distribution method for this:
1/2r - 3 = 2(4 - 3/2r)
Multiply 2 by everything inside the parentheses:
1/2r - 3 = 8 - 3r.
Move variables to one side, and numbers to another:
1/2r + 3r = 8 + 3.
3 1/2r = 11.
7/2r = 11.
Divide by 7/2:
r = 22/7.
Not sure this is correct.
