Answer:
(2w-1)/5+w+2=2w
We simplify the equation to the form, which is simple to understand
(2w-1)/5+w+2=2w
Reorder the terms in parentheses
( + 0.4w-0.2)+w+2=2w
Remove unnecessary parentheses
+ 0.4w-0.2+w+2=2w
We move all terms containing w to the left and all other terms to the right.
+ 0.4w+1w-2w=0.2-2
We simplify left and right side of the equation.
-0.6w=-1.8
We divide both sides of the equation by -0.6 to get w.
w=3

Answer:
7 hr * 12 days = 84 hours
10*84 = 840 man-hrs to build the wall
----
14 men * 8 hr = 112 man-hrs/day
840/112 = 7.5 days

Answer:
y = 3/2x - 4
Step-by-step explanation:
y = mx + b
*plugging in slope*
y = 3/2x + b
*finding b (aka y-intercept, starting value, when x=0) by plugging in x and y values from point (2, -1) )*
-1 = 3/2 * 2 + b
-1 = 3 + b
b = -4
so: y = 3/2x - 4
Answer:
y=9
Step-by-step explanation:
6y=79-25
= 6y= 54
= y=54/6
= y= 9
