Choose the statement that describes its solution 5(y+1)-7=3(y-1)+2y

DiKsa [7]

$5(y + 1) - 7 \: \: = 3(y - 1) + 2y \\ 5y + 5 - 7 \: \: \: = 3y - 3 + 2y \\ 5y - 2 \: \: \: \: \: \: = 5y - 3$

this is the solution...but these are not equal !

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6

Ira Lisetskai [31]

Answer:

see the explanation

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

$60=\frac{(88+94+92+98+x)}{5}$

solve for x

Combine liker terms in the right side

$60=\frac{(372+x)}{5}$

Multiply by 5 both sides

$300=372+x$

Subtract 372 both sides

$300=372+x$

$x=-72$ -----> this is not make sense

The grade cannot be a negative number

For x=0

The minimum average grade is

$\frac{(372)}{5}=74.4$
