Divide 7 by both sides and it should be s=4
5(2x-3)=155
10x-15=155(solve/multiply 5 by the numbers/variables in the parentheses first)
10x=170(add 15 to each side)
Divide 170 by 10x
170÷10x=17
x=17
Creo que es 10. No se tanto
I believe its already in standard form so you would just add it
First, we need to find out how much the price increased by.
$4.50 - $3.75 = $0.75
Now we have to figure out what percent $0.75 is of $3.75. To do this, we divide $0.75 by $3.75.
The answer is 0.2. Now, we convert this into a percent by moving the decimal to the right by to spaces: 0.2 = 20%
The percent of increase is 20%.
