His error is he forgot the 2 in 2 3/4
Y = 2x - 1...slope here is 2 and y int is -1
2y - 4x = 7
2y = 4x + 7
y = (4/2)x + 7/2
y = 2x + 7/2...slope here is 2 and y int is 7/2
When the slopes of the lines are the same, and the y intercepts different...this means they are parallel lines
5/7 is a fraction in simplest form. To simplify a fraction, you always have to divide the numerator and denominator by the same number other than 1. Since 5 and 7 are only divisible by 1, 5/7 is the simplest form of the fraction.
Hope this helps.
The answer would be 3, to find this you would do .10 x 30 to get 3
Hello,
Your correct answer would be: 150, b/c .30 times 150 equal's 45.
Hope this helps 150 is your answer!
