Step-by-step explanation:
One
Since you are asked to solve this using a graphing tool, here is the results as graphed by Desmos.
The point you want is (3,2)
The answer is 2.
Two
Multiply the second equation by 2
2[0.5x - y = 10]
x - 2y = 20 Add the first equation
<u>x + 2y = 16</u>
2x = 36 Divide by 2
x = 36/2
x = 18
Since this is all you are asked for, x = 18 is the answer.
Three
y is an exterior angle.
It is the sum of the two (given) remote interior angles.
y = 35 + 105
y = 140
x and y are supplementary (they add up to 180o
x + y = 180
x + 140 = 180
x = 180 - 140
x = 40
y - x = 140 - 40
y - x = 100

Given:
The gluten ratio is 13 mg per L of food.
Note that
1 L = 1000 mL (milliliter)
1 mg = 10⁻³ g
1 μg = 10⁻⁶ g
Therefore
1 mg = 1000 μg
The gluten ratio is
