Answer:
x=2
Step-by-step explanation:
If 3x + y = 7, then y= 7 - 3x.
Substitute in x - 2y = 0
So:
x - 2(7-3x)=0
x-14+6x=0
7x=14
x=2
Answer:
y = 2x + 5
Step-by-step explanation:
First find the slope:
5-7/0-1 --> -2/-1 --> (2)
Now use the point-slope form to find the slope-intercept form:
y-7 = 2 ( x - 1)
y - 7 = 2x - 2 add seven to both sides...
y = 2x + 5
The answer is 14 because 3 1/2 multiplied by 4 is 14. Hope this helps
To find out how many miles does each person run, we can divide the total miles by 4 as each part is equal:
14÷4
=3.5miles
Each of them have to run 3.5 miles.
To prove the answer, we can multiply it by 4 to see if it is the original distance:
3.5 x 4
=14miles
Therefore 3.5 is the answer.
Hope it helps!
