Which equation shows y = 3/4x - 5/2 in standard form?

1 answer:

4 0

The format for a standard form is ax+by=c.
So, we need to get rid of fractions in the equation first.
To do this, multiply both sides by the "LCM" of the fraction denominators..
The LCM of 4 and 2 is 4. So, multiply both sides by 4:
4y = 3x - 10
Now, change it to standard form by subtracting 3x from both sides:
-3x + 4y = -10
This doesn't match any of the choices. Am I wrong or is the choices wrong? idk

Answer:

19.17 feet of lace will be leftover.

Step-by-step explanation:

Given:

Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.

Now, to find the feet of lace will be leftover.

Total feet of lace = 46.

Kaitlyn needs lace for the quilt = 322 inches.

So, by using conversion factor we change inches into feet:

12 inches = 1 foot.

322 inches = $\frac{322}{12} =26.83\ feet.$

Feet of lace she need for the quilt = 26.83.

Now, to get the feet of leftover lace:

Total feet of lace - feet of lace she need for the quilt

$=46-26.83$

$=19.17\ feet.$

Therefore, 19.17 feet of lace will be leftover.
