<span>0.0525
The percent sign means divide. So you just move the decimal over two places to the left</span>.<span>To find the percentage, we multiply this 'decimal' form of the percent by 200.
0.0525*200 = 10.5
The 200-pound piece of alloy contains 10-1/2 pounds of copper. </span>

If q/18 = 5 what does q = to
qaws [65]

Answer:

Q= 90

Step-by-step explanation:

To do this problem you need to get q by itself and to do that you would move the 18 over

When you move the 18 over however you need to multiply and you will get 90

When ever you want to get a variable by itself always remember to switch the sign so if it was positive then switch it to negative and vice versa. It will also apply to multiplication and division just like this one
