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.
Answer:
Given the equation: 
Distributive property of multiplication states that when a number is multiplied by the sum of the two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,
Now, using distributive property to LHS and RHS, we get
Combine like terms on RHS;
or
Subtract 3 from both sides of an equation;
2x+3-3 =4x+3-3
Simplify:
2x = 4x
or
2x = 0
⇒ x =0
Therefore, the value of x in the given equation
is 0.
Answer:
x=20
Step-by-step explanation:
sin¢=cos90-¢
therefore; 3x-15+x+25=90
4x+10=90
4x=90-10=80
x=20
