Answer:
a) the slope is 2/-1 or just -2
b) the slope is 1/1 or just 1
Step-by-step explanation:
You can find slope (rise/run) by picking a point on the graph. For example on question a I chose the point (-2, 1) i then counted how far my run was, which is 2, and my rise (or how far down it went) was -1. Therefore my slope was 2/-1 or just -2.
X/3=x+2/5
5x = 3(x+2)
5x = 3x + 6
2x = 6
x = 3
answer
D.3
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:
4 12
3 18
5 20
7 42
5 15
Step-by-step explanation:
all of the above form a proportion
Answer:
x = 11.
Step-by-step explanation:
We have 2 lines crossing 3 parallel lines so:
5/6 = x-1 / 12
6(x-1) = 5*12
6x - 6 = 60
6x = 66
x = 11.
