Answer:
How long will it take a plane to fly 310 miles at 124 miles per hour?
A.) 1.5h
B.) 2h
<u>C.) 2.5h
</u>
D.) 3h
Step-by-step explanation:
Let width be x,
Length: 3+x
P=2(l+w)
54=2(x+(x+3))
54/2=2x+3
27=2x+3
27-3=2x
24=2x
24/2=x
12=x
Therefore, the width is 12 inches and the length is (12+3)=15 inches
Hope I helped :)
Assuming you want to solve for x:
Make 15x and 15 add up to 180 in an equation since they form a straight line. A straight line is 180 degrees.
15x + 15 = 180
- Subtract 15 from both sides.
15x = 165
x = 11
After working it I got x = 2
