Answer:
1 ton on wednesday!
Step-by-step explanation:
We need to go step by step for this one.
On monday the factory used 11/15 of a ton, while tuesday required 14/30 a ton more than that. To find tuesday's amount we must take 11/15 and add 14/30 to that.
11/15 + 14/30 = 1 1/5
Tuesday = 1 1/5 of a ton
On wednesday the factory uses 5/6 of the amount used on tuesday, which is 1 and 1/5 of a ton.
1 1/5 times 5/6 = 6/5 times 5/6
Anything multiplied by their reciprocal is 1, so the answer is 1. On wednesday 1 ton of grapes was used on wednesday!
I’m not sure if this may be to hard of a method for you depending on which grade you are in but I’ll try and explain the best I can.
Use the formula:
Y2 - Y1
————
X2 - X1
Take two points from the line: (10,30) and (40,50)
Only because they have exact values
(10,30) and (40,50)
The 10 is X1 because it’s the x of the first coordinate. 30 is Y1 for the same reason
The 40 is X2 because it’s the X of the second coordinate. 50 is the Y2 for the same reason
Substitute this into the formula
50-30
———-
40-10
= 20
—-
30
Which simplifies to 2
—
3
So the slope of the line is 2
—
3
I hope this helps.
Hello,
1) y-8=(8-2)/(4-2)(x-2) ==>y-8=3(x-2) (not in answer!)
2) y-2=3(x-2) ==> Answer A.
