18. Set the the two equations equal and solve.
Answer: See explanation
Step-by-step explanation:
Your question isn't really clear. Let me help you rephrase it and solve.
Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.
The total hours that Cesar has used in practicing will be:
= 1 1/2 + 2 1/4 + 1 1/2
= 5 1/4
To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:
= 10 - 5 1/4
= 4 3/4 hours.
Cesar needs to practice for 4 3/4 hours more.
To convert 3/4 to a percent we need to convert 3/4 to a decimal and then multiply the decimal by 100. Lets do it:-
To convert a fraction to a decimal we have to divide the numerator by the denominator.
3/4
3 ÷ 4 = 0.75
Decimal = 0.75
0.75 × 100 = 75
75%.
So, 3/4 in percent form is 75%.
Hope I helped ya!! xD
You can use the formula 2(a+b

This will get you 161.5 ft

The great x value for what? Can you give us the equation?
