Answer:
0=0
or as separate equations:
y=1/2
X=4y+2
Explanation:
If we solve your system by elimination:
x−4y=2;4x−16y=8 -->
Multiply the first equation by -4,and multiply the second equation by 1.
−4(x−4y=2)
1(4x−16y=8)
Becomes:
−4x+16y=−8
4x−16y=8
Add these equations to eliminate x:
0=0
1 inch for 40 inches. 7 inches would be 280 miles
Answer:
0.45
Step-by-step explanation:
Entertainment = 3/20

You can simplify this into a decimal, so 9 / 20 = 0.45
Answer:
10 miles
Step-by-step explanation:
