What is the value of x?
Answer:he will use 45 minutes to burn 540 calories . he spend a total of 50 minutes ie including 5 minutes of rest.
Step-by-step explanation: 1 minute burns 12 calories
Therefore 540÷12 = 45 minutes plus 5 minutes of rest = 50 minutes.
10 and 58
10*58=580
10*3+28=58
95°

Paige was assigned 40 math problems.
An expression is a combination of numbers, variables, and operators that represents a mathematical quantity or relationship. Expressions do not contain an equals sign (=) and are not true or false statements. Instead, expressions are evaluated to produce a value or another expression.
Let's call the total number of math problems Paige was assigned "x".
Paige solved the first 32 problems, so she still had to solve x - 32 problems after dinner.
We know that she finished the last 20% of the assignment after dinner, which means she solved 80% of the problems before dinner.
80% of x can be written as 0.8x.
So, the equation we can set up is:
x - 32 = 0.2x
Solving for x, we get:
0.8x = 32
x = 40
Therefore, Paige was assigned 40 math problems.
