Step-by-step explanation:

4/3(6y+21)-17=43

move all terms to the left:

Help! What is the answer?
spayn [35]

Answer:

(10,0)

Step-by-step explanation:

4x - 5y = 40

To find the x intercept, set y =0 and solve for x

4x - 0 = 40

4x= 40

Divide by 4

4x/4 = 40/4

x = 10

The x intercept is 10

(10,0)

Sarah needs 10 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabri
Aleks [24]
<h2>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:

1ft=0.305m

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

We have that:

10*1ft=10*0.305m\\\\10ft=3.05m

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

\frac{1m}{1.50(dollars)}=\frac{3.05m}{cost}\\\\cost=\frac{3.05m*1.50(dollars)}{1m}=4.575(dollars)=4.58(dollars)

Hence, we have that the cost of the fabric will be $4.58.

The correct option is: D.$4.58​

Have a nice day!
