Answer:
y=1
x=7/4
Step-by-step explanation:
4x + 5y = 12
3x + 4y = 9.25
4x + 5y = 12
12x + 16y =37
-12x -15 y =-36
12x + 16y =37
y=1
x=7/4
Answer:
0.84
Step-by-step explanation:
Use a calculator. That would be 0.84.
3*21
Note that 63/75 = ---------- = 21/25. Multiplying top and bottom by 4 results
3/25 in 0.84 (so this answer checks out ok)

Hello!</h2>
The answer is:
The fabric will cost $4.58
D.$4.58
<h2>Why?</h2>
Since it's a conversion exercise, we need to pay special attention to the conversion procedure.
From the statement we know that:

So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.
We have that:

Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:

Hence, we have that the cost of the fabric will be $4.58.
The correct option is: D.$4.58
