Define x and y
---------------------------------------------
Let x be the amount of the cream (which has 2.5% of hydrocortisone)
Let y be the amount of the water-washable base. (which has 0% of hydrocortisone)
---------------------------------------------
Construct the 2 equations:
---------------------------------------------
Both x and y must add up to 120g
⇒ x + y = 120
Both x and y must add up to only 1% of hydrocortisone.
⇒0.025x + 0.0y = 0.01 x 120
⇒0.025x = 1.2
---------------------------------------------
Solve x and y:
---------------------------------------------
x + y = 120 ----------------- (equation 1)
0.025x = 1.2 ----------------- (equation 2)
---------------------------------------------
From equation 2:
---------------------------------------------
0.025x = 1.2
x = 1.2 ÷ 0.025
x = 48
---------------------------------------------
Substitute x = 48 into equation 1:
---------------------------------------------
x + y = 120
48 + y = 120
y = 120 - 48
y = 72
-------------------------------------------------------------------------------------------------------
Answer: 48g of 2.5% of the cream and 72g of the water washable base are needed to make 120g of the prescription.

Determine if the relation is a function.
The relation is a function.
Answer:
x = -8°
Step-by-step explanation:
Angle 2
Since the triangle is isosceles, Angle 2 is the same as the missing angle
So angle 2 would be:
180 - 34 = 2(angle 2)
So 146 = 2(x + 81)
146 = 2x + 162
146 - 2x = 162
-2x = 16
x = -8
Check
146 = 2(-8+81)
146 = 2(73)
146 = 146
Correct!

Answer:
12.2
Step-by-step explanation
The triangles are congruent, so the sides are as well. Add 6.1 and 6.1 and you will get 12.2
The midline would be horizontal.
The top of the line is at 12, the bottom is at 6
The midline would be at 9
The answer is b.9
