Answer:
The answer is 2:1 because ratio is just like simple division
Answer:
8
Step-by-step explanation:
140-122=18
18-10=8
Form an equation to describe the situation
x+y=10
Then use the other information they gave you and form another equation
x-y=2
You can add the two equations together, and you see that the y variables cancel out(elimination)
2x=12
Solve for one variable and then plug it back into the original equation
x=6
6+y=10
y=4
Answer:
Step-by-step explanation:
1.75x+1.25y=2 Multiply this equation by 4
7x + 5y = 8
7x+5y=9
As you can see, the xs and ys have the same coefficient. These lines are parallel. There are NO solutions. Just to show you that, here is a graph.
