Answer:

y=10.75

Step-by-step explanation:

46 + 1) + y = 5(y - 1) +9

47+y=5y-5+9

47+y=5y+4

Collect like terms

47-4=5y-y

43=4y

Divide by 4

43/4=4y/4

43/4=y

y=10.75

If a is the average (arithmetic mean) of 6m and 10, b is the average of 4m and 4, and c is the average of 14m and 16, what is th

Paha777 [63]

Answer:

6m+7.5

Step-by-step explanation:

the arithmetic mean is the average of two numbers

it is given that a is average of 6m and 10

so $a=\frac{6m+10}{2}$

b is the average of 4m and 4

so $b=\frac{4m+4}{2}$

c is the average of 14m and 16

so $c=\frac{14m+16}{2}$

now the average of a ,b and c is given by

$average=\frac{a+b+c}{3}=\frac{\frac{6m+10}{2}+\frac{4m+4}{2}+\frac{14m+16}{2}}{3}=6m+7.5$

Fill in the blanks to complete the description of how to solve the equation.

Svetach [21]

Answer:

The value of x is the given expression is $\frac{-3}{2}$

Step-by-step explanation:

Given equation is 28x-56=22x-65

To simplify the given equation as below:

28x-56=22x-65

Subtracting 22x on both sides we get

28x-56-22x=22x-65-22x

6x-56=-65 ( adding the like terms )

Adding 56 on both sides we have

6x-56_56=-65+56

6x=-9

Dividing by 9 on both sides

$\frac{2x}{3}=-1$

Multiply into $\frac{3}{2}$ on both side

$\frac{2x}{3}\times(\frac{3}{2})=-1\times(\frac{3}{2})$

$x=\frac{-3}{2}$

Therefore $x=\frac{-3}{2}$

The value of x is the given expression is $\frac{-3}{2}$
