1 1⁄8 miles = how many yards
Paul [167]

Answer:

1980 yards

Step-by-step explanation:

We need to convert 1 1/8 miles into yards. For doing so we can conclude the following and use the information gathered:

1 mile = 1760 yards.

1/8 mile = 220 yards

In that case, we will add the two shown above together to find the total as well as our answer.

1760 + 220 = 1980

Thusly, there are  \boxed{1980} yards in 1 1/8 miles.

Hope this helps!

Elimination Method<br> 2x-4y=12 -x+2y=-6
Readme [11.4K]

Answer:

The given system has INFINITE NUMBER OF SOLUTIONS.

Step-by-step explanation:

Here, the given system of equation is given as:

2 x - 4 y = 12   ...  (1)

- x + 2 y = -6   ......  (2)

Now, to use the ELIMINATION METHOD we either need to cancel out x coefficients or the y coefficient.

Now, to cancel out the x- coefficient in both the equations:

Multiply equation (2) with 2 and add with (1), we get:

2 x  - 2x + 4 y - 4 y = 12 - 12  

or, 0 = 0

Hence, the given system has INFINITE NUMBER OF SOLUTIONS.
