Answer:

The answer to your question is w = 1.2

Step-by-step explanation:

Data

Equation 7(w + 2) + 0.5w = 5

Expand 7w + 14 + 0.5w = 5

Simplify like terms (7w + 0.5w) + 14 = 5

7.5w + 14 = 5

Subtract 14 in both sides

7.5w + 14 - 14 = 4 - 15

Simplify

7.5w = - 9

Divide both side by 7.5 7.5/7.5w = 9/7.5

Simplify

w = 1.2

2nd option

Step-by-step explanation:

the mean is calculated as

mean = $\frac{sum}{count}$

= $\frac{4x+5+7x-6-8x+2}{3}$

= $\frac{3x+1}{3}$

= $\frac{3x}{3}$ + $\frac{1}{3}$

= x + $\frac{1}{3}$

Pleaz Helpz!!! I needz this done before my final!!!

Marta_Voda [28]

the perimeter of the field is 442

width=w

the length of the field is 9 yards less than quadruple W

L=4x - 9

the perimeter is P=2L+2W

you can plug in the values

P= 2(4w-9) + 2W

plug in 442 for P

442= 2(4w- 9) + 2W

442= 8w - 36 + 2W

478 =8w + 2W

478= 10W

47.8 is your answer!!!
