12 boxes would be 22 pounds.
Answer:
%
Step-by-step explanation:
Probability is found by first forming a fraction where the numerator represents the number of desired outcomes and the denominator represents the total number of outcomes. In this case, the desired outcomes is the amount of times the coin lands on heads (9) and the total outcomes is the number of times the coin is tossed (20):

Divide numerator by denominator to get a decimal: 9÷20= 0.45
Multiply the decimal by 100 to get a percent: 0.45 x 100 = 45%
4(-5y) + 2y = 180
-20y + 2y = 180
-18y = 180
y = -10
x = 50
I think you have multiply 5x4 which equals 20 then 20 divided by 10 which equals 2 and that’s ur answer
