Answer:
Slope = 3
y-intercept: 0
Step-by-step explanation:
(1,3) and (2,6)
Slope: (6-3)/(2-1) = 3/1 = 3
y-intercept: 3 - (3)(1) = 3-3 = 0
y = 3x
Answer:
810
Step-by-step explanation:
3 x 3 x 9 x 10 = 810 [times means multiply]
Answer:
80 copies
Step-by-step explanation:
4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.
Answer:
20 ton
Step-by-step explanation:
We created a system of two separate equations to answer these questions.
"y" will be the total cost to transport the sugar
"x" will be the amount of sugar transported
Therefore, we have to:
y = 3995 + 225.50 * x
y = 6500 + 100.25 * x
We must establish these equations equal to each other because it asks how much of x is necessary to make the same amount of y, therefore:
3995 + 225.50 * x = 6500 + 100.25 * x
solved we have:
225.50 * x - 100.25 * x = 6500 - 3995
125.25 * x = 2505
x = 2505 / 125.25
x = 20
which means that when the amount of sugar transported is 20 tons, the price is the same
86/139*100%= 61.87%
The final answer is 61.87%~
