Answer:
Step-by-step explanation:
Check attachment for better understanding of the data given
Since the given data is a linear data,
Then we can use equation of a line to find the relationship between x and y
Let pick any tel point from the given data
P1 = (x1, y1) = (1, 80)
P2 = (x2, y2) = (2, 160)
Then, equation of alone given two points can be determine using
∆y/∆x = y-y1 / x-x1
y2 - y1 / x2 - x1 = y-y1 / x-x1
160 - 80 / 2 - 1 = y - 80 / x - 1
80 / 1 = y - 80 / x - 1
Cross multiply
80(x - 1) = 1(y - 80)
80x - 80 = y - 80
Add 80 to both sides
80x - 80 + 80 = y - 80 + 80
80x = y
Then,
y = 80x
Then, the mistake useful made is multiplying x by 8 instead of multiply it by 80
So, the correct option is
D. Yosef should have multiplied the x-values by 80 to get the y-values.

Answer:
100+130=3000
Step-by-step explanation:
<h2>Brainlest me please hehehe</h2>
1. find the LCD of 3 and 4 (12). so now your fractions are 5 4/12 and 3 9/12 perimeter is 2l + 2w so 2 (5 4/12) + 2( 3 9/12) = 10 4/12 + 7 6/12 = 17 10/12 or 17 5/6. this is reasonable because that the average perimeter of a sandbox.
2. LCD again is 12, so the fractions are 5 10/12 and 2 1/12. turn those into mixed fractions and get 70/12 and 25/12. 45/12 or 3 3/4. So she babysits 3 3/4 hours during the week.
3. The LCD for this is 8. now the fractions are 2/8 and 1 7/8 or 15/8. add 15/8 and 2/8 to get 17/8 or 2 1/8. He is using a total of 2 1/8 cups of flour.
