To solve this problem you must apply the proccedure shown below:
1. You have that :
-The <span>estimate from the moving is $675 for 6 hours of packing and 5 hours of moving.
- </span>The cost will decrease to $425 for 4 hours of packing and 3 hours of moving.<span>
x: rate for packing.
y: rate for moving.
6x+5y=675
4x+3y=425
2. When you solve the system of equations shown above, you obtain:
x=50
y=75
Therefore, the answer is: $50 (Rate for packing) and $75 (Rate for moving).

To find the x-intercept, make y equal to 0. Then you get (7/2,0)
To find the y-intercept, make x equal to 0. Then you get (0,7)
Answer:
Step-by-step explanation:
Part A. John will not be painting the floor area of that of the door or window openings.
Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.
Part C.
We first need to find the area to be painted.
A=floor+2(wall1)+2(wall2)-window-door
A=14(7)+2(7)8+2(14)8-3(6)-3(7)
A=98+112+224-18-21
A=395 ft^2
Since a gallon of paint will cover 350 ft^2
395ft^2(gal/350ft^2)=1.13 gal
John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)
Answer:
8.55 inches tall
Step-by-step explanation:
equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.
Now plug in 4.6 for t you get:
h = -0.75t + 12
h = -0.75(4.6) + 12
h = -3.45 +12
h = 8.55 inches tall
