It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions<span> would mean that any value for the variable would make the </span>equation true. I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
The total 8 ft of fabric will cost $ 2.80416.
Step-by-step explanation:
The length of the cloth needed by Joy = 8 ft
Now, 1 ft = 0.305 m
⇒ 8 ft = (8 x 0.305 ) m
= 2.4384 meters
or, Joy needs 2.4384 meters of cloth for her project.
Now, the cost of 1 m cloth = $1.15
So, the cost of 2.4384 m cloth = $( 1.15 x 2.4384)
= $ 2.80416
or, the cost of 8 ft cloth is $ 2.80416 .
Hence, the total 8 ft of fabric will cost $ 2.80416.
Train A’s length is 1120 feet, and Train B’s length is 1020 feet. Therefore, only Train B meets the requirement.
Answer:
23 starfish, 7 octopi
Step-by-step explanation:
x=starfish
y=octopi
x+y=30
5x+8y=171
-5(x+y=30)
5x+8y=171
-5x-5y=-150
5x+8y=171
3y= 21
y=7
x+7=30
x=23
23 starfish, 7 octopi
