16/20 = 100/x
1.) 4/5 = 100/x
Simplify the fraction so it’s easier!
2.) 4x = 500
Cross multiply.
3.) x = 125
Divide both sides by 4 to keep it even.

Answer:
a) $4.86
b) $57.39
Step-by-step explanation:
a) To find how much sales tax Allison paid, find the sale price. The price of the game was 12% off. This means Allison paid 88% of the new price. COnevrt 88% to 0.88. The multiply it with the price.
0.88*59.69 = 52.53
The sale price was $52.53. She will pay 9.25% or 0.0925 of the sale price.
0.0925 (52.53) = 4.86
b) She pays in total $52.53 + 4.86 = 57.39
Answer:
x =8
y = 4sqrt(2)
z = 4sqrt(2)
Step-by-step explanation:
The easiest one to calculate is x
If it is a 45 -45-90 degree triangle then AB = BC=x
Since AB =8 then BC =8 and x=8
The next easiest to calculate is z
If it is a 45 -45-90 degree triangle then AD = BD=z
Using the Pythagorean theorem
z^2 +z^2 = 8^2
2z^2 =64
Divide by 2
x^2 = 32
Taking the square root of each side
z = sqrt(16)sqrt(2)
z=4sqrt(2)
Finally, we can find y
If it is a 45 -45-90 degree triangle then BD = DC
BD =z =4 sqrt(2) = DC = y
Therefore y =4 sqrt(2)
