Answer:

The answer is B. 0

Step-by-step explanation:

If the problem is d + (-d), then the answer is 0. Suppose that d = 7. Then it would be 7 + (-7), which is 0. You can't get any other number from that equation unless you do d + d or d - d.

Hope this helps.

2x - 3y &gt; -12.<br> Rewrite the inequality so that y is isolated
kifflom [539]

Answer:

y < 2/3x + 4

Step-by-step explanation:

Hi there! So first, we need to subtract 2x from both sides:

-3y > -2x - 12

Now, we need to divide both sides by -3 to isolate y. Since we are dividing by a negative value, <u>our</u><u> </u><u>inequality</u><u> </u><u>symbol</u><u> </u><u>will</u><u> </u><u>be</u><u> </u><u>flipped</u><u> </u><u>from</u><u> </u><u>></u><u> </u><u>to</u><u> </u><u><</u><u>.</u>

Your final answer is:

y < 2/3x + 4

ra1l [238]

Answer:

her profit is $25

Step-by-step explanation:

And, she can make 4 blankets from one piece of fabric

Now she sold the blankets for 10 each

So we need to find out the profit

As we know that

Profit = Selling cost - purchasing cost

= (4 × $10) - $15

= 40 - $$5

= $25

hence, her profit is $25
