$518.5 = $375 + $41x
Now that we have our equation, let's solve for the # of hours
Subtract $375 from both sides
$143.5 = $41x
Divide both sides by $41
3.5 = x
The number of labor hours was 3.5
11.94 = 6 pounds
11.94/6 = 1 pound
1 pound = 1.99
8 pounds = 1.99*8
8 pounds = $15.94
3.5 divided by 2.54=1.38 cm rounded to the nearest tenths place :)
Answer:
w= 7/4 +1/4 √89 OR w= 7/4 -1/4 √89
Step-by-step explanation:
2w^2-8w-1= (w-2)^2
Multiply (w-2)^2 by (-1)
2w^2-8w-1= -w+2^2
Add w to both sides
2w^2-7w-1= 4
Add 1 to both sides therefore that -1 cancels
2w^2-7w=5
Get the equation equal to 0 by subtracting 5 from both sides
2w^2-7w-5=0
Use the quadratic formula to solve
x= -(-7) plus or minus √(-7)-4(2)(-5)/2(2)
7 plus or minus √89/4
Answer:
The equation of the line is:

Hence, option C is correct.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
Given the table
Gallons Miles Driven
8 224
10 280
4 112
Finding the slope between any two points, let say (8, 224) and (10, 280)




now substituting (8, 224) and m = 28 in the slope-intercept form of line equation

224 = 28(8) + b
224 = 224 + b
b = 0
Thus, the y-intercept b = 0
now substituting b = 0 and m = 28 in the slope-intercept form of line equation



Therefore, the equation of the line is:

Hence, option C is correct.
