Answer:
C
Step-by-step explanation:
use a proportion
( 3/4 ) / 1 1/8 = ( 4/4) / x teaspoons
x = 1.5
L= length
W= width= 9 yards
Perimeter= 72 yards
Plug in the numbers you know and solve for L.
Perimeter= 2L + 2W
72= 2L + 2(9)
72= 2L + 18
subtract 18 from both sides
54= 2L
divide both sides by 2
27= L
CHECK:
72= 2(27) + 2(9)
72= 54 + 18
72= 72
ANSWER: The length is 27 yards

A. M=16x
B. T=20x+480
C. 580=20x+480
100=20x
x=5
<span>We will call A to the number of hours traveled by Annie and B the number of hours travelled by Brian. Then Annie traveled 5 times plus 2 hours than Brian, that is
A = 5 * B + 2. And the total number traveled by both of them was 20, so: A + B = 20
Next step is solve both equations putting value of A in the second equation:
5 * B + 2 + B = 20 that is the same than:
6 * B = 18 and:
B = 3 then:
A = 5 * 3 +2
A = 17
The solution is Annie traveled 17 hours and Brian only traveled 3 hours.</span>
