Answer:
X=-1
Step-by-step explanation:
-5x+1=6

5x-1=-6
add 1 to - 6
5x = -5
divide both sides by 5
X=-1
To find the width, divide the area by the length.
Width = 9/10 / 2/5
When dividing fractions flip the second one over and multiply:
Width = 9/10 x 5/2 = (9 x5) / (10 x 2) = 45/20 = 2 and 1/4 miles.
Answer:
A
Step-by-step explanation:
y= x+1 at the same time y=4x+5
x+1= 4x+5, so answer is A
Ten times two point five plus thirteen point five
10 x (2.5 + 13.5) = 160
