O (3.-53

(3.)
no solution
infinitely many solutions
Answers
Answer:
X+2y=4
4+2y=x
2(2+y)=x
2x-2y=5
2(x-y)=5
x-y=5/2
Answer:
(x, y) = (3, 1/2)
Step-by-step explanation:
x + 2y = 4
2x - 2y = 5
There is more than one way to do this. I will do it by substitution.
From the first equation, x + 2y = 4, so x = (-2y) + 4
Now, in the second equation, I will replace x with (-2y + 4)
2(-2y + 4) - 2y = 5
-4y + 8 -2y = 5
-6y + 8 = 5
-6y = -3
6y = 3
y = 3/6
---------------------------------> y = 1/2, one part of the answer
Now I can go back to the first equation, and relpace 'y' with 1/2
x + 2(1/2) = 4
x + 1 = 4
-----------------------------------> x = 3, the other part of the answer
So now we believe the solution is (x, y) = (3, 1/2)
Now check the answer, back in the original equations!!
------> In the first equation, we would have 3 + 2(1/2) = 4.
3 + 1 = 4
That is true
-------> In the second equation, we would have 2(3) - 2(1/2) = 5
6 - 1 = 5
That is true
Our answer is found and checked.
(x, y) = (3, 1/2)
How do I find the value of y?
Answers
Answer:
y = 27
Step-by-step explanation:
line segment BA and CD are congruent, turn them into an equation
3y - 59 = y - 5
subtract 1y from both sides, you get 2y - 59 = -5
then, add 59 to both sides and the equation is now 2y = 54
divide each side by 2 and you get the value of y (y = 27)

Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?
Answers
Answer:
Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.
Step-by-step explanation:
18 ÷ 10 = 1.8 (Lisa's rate)
14 ÷ 8 = 1.75 (Marie's rate)
1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)
1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)
