500g = $0.95
100g = $0.95 ÷ 5 = $0.19
800g = $0.19 x 8 = $1.52

Here are some factors of 20!
1x20=20
2x10=20
4x5=20
5x4=20
Therefore there are 4 factors of 20.
Answer:
Step-by-step explanation:
Answer:
x = 20√2 and y = 20√3.
or x = 28.28 and y = 34.64 to the nearest hundredths.
Step-by-step explanation:
Take the 2 'inside' triangles. They are similar.
So we have x / (60-40) = 40 / x
x/ 20 = 40 /x
x^2 = 800
x = √800
x = 20√2
y = √(800 + 20^2)
= √(1200)
= 20√3.
X = unknown number
10x - 16 = 2x
Subtract 10x from both sides to isolate the variable on the right side of the equation.
-16 = -8x
Divide both sides by -8 to get x alone.
2 = x
