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.

Answer:
16/21
Step-by-step explanation: 4 x 3 = 12, 3 x 7 = 21, 13/3 - 25/7 raise to the first common denominator, 91/21 - 75/21 = 16/21
Answer:
1) P(tacos)= 10/30= 1/3
2) P(Pizzas)=18/30 =3/5
3) P(T AND P)= 5/30= 1/6
4) P(T OR P)= P(T) +P(P) - P(T AND P)
= 10/30 +18/30 -5/30
= 23/30
The measure of angle 2 is 
Explanation:
Given that 
and 
are complementary angles.
Also, the measure of angle 1 is 
We need to determine the measure of
Since, we know that the complementary angles add up to 90°, then the angles and add up to 90°.
Thus, we have,
Substituting the value of in the above expression, we have,
Subtracting both sides by 76°, we get,
Simplifying, we have,
Thus, the measure of angle 2 is
