First you would distribute the -3
-3x+1+7x=27
Combine like terms
4x+1= 27
Minus 1 on both sides
4x= 26
Divide by 4
X= 6.5
The two rectangles are similar and the scale factor is 3:4
Hope this helps, the y intercept is 3 ans the x intercepts are +1.3 and -1.3
21 divide by 4 is 5.25. She travels 5.25 miles per hour. 42 divide by 5.25 is 8. It would take 8 hours for Shelly to bike 42 miles.
