Answer:
Infinite Solutions
Step-by-step explanation:
x + 2y = 10
6y = 3x - 30
To solve for x and y we use substitution method
Let's solve the first equation for x
x + 2y = 10
Subtract 2y on both sides
x = 10 - 2y
Now plug in x in second equation
6y = -3x + -30
6y = -3 (10-2y) - 30
6y = -30 + 6y - 30
6y = 6y
Both sides are the same, so both x and y have infinite solutions.
Answer:
140
Step-by-step explanation:
Because the lines are parallel:
Hope this helps!
The correct answer is B. 72 because you can multiply 3*6*4 to represent every combination possible.
180-106=74
X is congruent to 2y
x=74
74/2= 37
y=37
(4z+6) is congruent to 106
106-6= 100
100/4 = 25
z=25
