Answer:
correct ans is option/graph Dbecoz 36/3 = 12
Answer:
636372
Step-by-step explanation:
the answer is 636372
We can simply set the two equations equal to each other:
60x+10=40x+70
We subtract 40x+10 from both sides to get:
20x=60
Divide by 20 to find that x=3. Substitute this back into either equation to find the amount of miles - using the first, 60*3+10=190, so the answer is D.
For lines a and b to be parallel, the sum of angle 1 and angle 2 must equal 180 degrees.
117 + 6x-12 = 180
Simplify the left side:
105 + 6x = 180
Subtract 105 from each side:
6x = 75
Divide both sides by 6:
x = 75/6
75/6 simplifies to 25/2
The answer would be B.
