Answer:
D.
Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
3/12 simplified is 1/4 because both the numerator and the denominator are divisible by 3. After dividing the numerator and denominator by 3, you get 1/4.
Answer:
B
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
35 divided by 12 is 2
So D is the answer
2x+1 = -3
2x + 1 -1 =-3
2x = -4
2x/2 = -4/2
x= -2
