That is 2 of the y^2
that means 2y^2 aka 2 times y^2
For number two you make four over five a decimal witch is zero point eight and then you multiply it by 7 and that will get you 5.6
<span> Final price=(Initial price)(100%-discount rate)
Final price=($415.80)(100%-20%)
Final price=($415.80)(80%)
Final price=($415.80)(0.8)
Answer:
Final price=$332.64 </span>
The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.
- <em>Let the current weight of Euclid = x</em>
- <em>Let the current weight of Pythagoras = T</em>
- <em>Let the January weight of Pythagoras = y</em>
The expression that represents the given scenario is written as;
- when Pythagoras lost 13 pounds: T = y - 13
- when Pythagoras gains 1.2 times Euclid's weight: = T + 1.2x
when Pythagoras weight is 1/4 pound less than weight in January:
T + 1.2x + 0.25 = y
y- 13 + 1.2x + 0.25 = y
1.2x - 12.75 = 0
Euclid's weight is calculated as follows;
1.2x = 12.75
The weight of Riemann is calculated as follows;
