3 * 7 = 21, so

Then

and you can rationalize the denominator to write this as

The correct answer would be the first one
Answer:
John and Pam are paid $8.5 for each hour worked. John's share of the money is $29.75.
Step-by-step explanation:
Let x = the hourly salary. John worked for 3.5 hrs, and Pam for two. We can represent this using the equation:
3.5x + 2x = 46.75, where the coefficients equals the amount of hours.
Let's solve for x!
5.5x=46.75
x = 46.75/5.5 = 17/2 = 8.5
John and Pam are paid 8.5 dollars per each hour worked.
To figure out John's share of the money, we will multiply the wage by the hours he worked.
8.5 x 3.5 = 29.75
Answer:

Step-by-step explanation:
Let
x ------> the next grade
we know that
To find the average grade sum the grades by the number of math test
so

solve for x
Combine liker terms in the right side

Multiply by 5 both sides

Subtract 372 both sides

-----> this is not make sense
The grade cannot be a negative number
so
For x=0
The minimum average grade is
