It would come out to 3x = 3x so it would be infinitely many solutions
Answer:
The length of the first piece is 4 inches, that of the second is 8 inches and the third 19 inches.
Step-by-step explanation:
Total length of the steel = 31 inches
Let the length of the first piece = x
let the length of the second piece = y
Let the length of the third piece = z
So,
y = 2x
z = 4x + 3
x + 2x + 4x +3 = total length of the steel = 31
7x + 3 + 31
7x = 31 - 3
7x = 28
x= 4 inches
Thus; y = 2x = 2 × 4 = 8 inches
z = 4x +3 = 4×4 +3 =19 inches
∴The length of the first piece is 4 inches, that of the second is 8 inches and the third 19 inches.
Answer:
3 miles is greater than 5000 yards by 280 yards.
Step-by-step explanation:
There are 1760 yards in a mile.
3*1760=5280
That means there are 5280 yards in 3 miles.
5280 > 5000
This means that:
3 miles > 5000 yards
Now, we can find the difference.
5280-5000=280
3 miles is greater than 5000 yards by 280 yards.
