This game isn't too bad.
We have a proportion which represents another number.
Basically the problem states that the ratio:
22/40 is applicable to the ratio of:
# Wins / # Games
I'll represent the # Wins with the letter W.
and I'll represent the # of Games with the letter G.
So we simply set them equal to each other.
22/44 = W / G
They gave us G = 162 games
22 / 44 = W / 162
Cross multiply. So, the denominator on the left side of the equation will multiply with the numerator on the right. While the denominator on the right multiplies with the numerator on the left.
44*W = 22*162
You'll probably need a calculator for 22*162, but you can use long multiplication if it isn't allowed.
44W = 3564
Divide 44 on both sides.
W = 3564 / 44
W = 81
C. 81 is our answer!
1. Average Speed is distance divided by time. So 363 divided by 165 is 2.2
2. For number 2 I am not sure if there is a missing piece to your question but the car has travelled 72 miles in 220 minutes
X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0
so either x^2 - 2 = 0 or x^2 - 1 = 0
so x^2 = 2 or x^2 = 1
so x = sqrt 2 , - sqrt2, 1 , -1 Answer
all the roots are real
