Answer:
a. 21/4, 11/2, 49/10, 5/1
b. James 5.5, Olivia 5 1/4, Feng 5, Carmela 4.9
Step-by-step explanation:
Okay so Omar had 2/15 of the votes and Scott had 3/5 which will go up to 9/15 before it was reduced down so 9 plus 2 is 11 so 15 minus 11 is 4 so Lindsey got 4/15 of the votes.
Answer:
Yes
Step-by-step explanation:
The negative sign was simply moved to either the numerator or denominator. Either way the number is still a negative one half.
Answer:
1) 5 ( 4h - 1 )
2) 5 ( 3r + 7 )
3) 2( -2p +5 )
Step-by-step explanation:
For no. 1 you have to find a <u>common factor (</u>a number that divides into both 20 and 5) which is 5 because 20 divided by 5 is 4 and 5 divided by 5 is 1. so you have to do 20h divided by 5 which is 4h (don't forget the h ! ) and you do -5 divided by 1 which is -1. Remember when you do any multiplying or dividing questions with negatives and positives :
minus + minus = minus (-5*-6 = -30)
positive + positive = positive (5*6 = 30) * equals multiplacation by the way
minus + positive = minus (-5*6 = -30)
positive + minus = minus (5*-6 = -30)

Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:
To solve the system, first we multiply by 2 both sides of the second equation, and we get:
So now the system is
Now we add the two equations, and we get:
So, we get
Now we can substitute this value of y into the eq.(2), and we get:
