You first multiply across
![\frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20)
and
![\frac{18}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%7D%7B1%7D%20)
=
![\frac{36}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B36%7D%7B3%7D%20)
. Then you divide the numerator(the top) by the denominator(the bottom) which is
![\frac{36}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B36%7D%7B3%7D%20)
=
![\frac{12}{1} or](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B1%7D%20or%20)
just 12
Answer:
2x - y - 7 = 0
Step-by-step explanation:
Since the slope of parallel line are same.
So, we can easily use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (8, 9)
and m is a slope of line passing through (x₁, y₁).
and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.
and, Slope = m = ![\dfrac{y_{b}-y_{a}}{x_{b}-x_{a}}](https://tex.z-dn.net/?f=%5Cdfrac%7By_%7Bb%7D-y_%7Ba%7D%7D%7Bx_%7Bb%7D-x_%7Ba%7D%7D)
here, (xₐ, yₐ) = (2, 7)
and, ![(y_{a},y_{b}) = (1, 5 )](https://tex.z-dn.net/?f=%28y_%7Ba%7D%2Cy_%7Bb%7D%29%20%3D%20%281%2C%205%20%29)
⇒ m = ![\dfrac{5-7}{1-2}](https://tex.z-dn.net/?f=%5Cdfrac%7B5-7%7D%7B1-2%7D)
⇒ m = 2
Putting all values above formula. We get,
y - 9 = 2 ( x ₋ 8)
⇒ y - 9 = 2x - 16
⇒ 2x - y - 7 = 0
which is required equation.
Answer:
I think it might be 78. I'm so sorry If I'm wrong I'm.not the bet at them but just try it
You count by 36 by adding at 36 every time u go up :
36, 72, 108,144 , 180 etc
Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!
