x=17+4y

-6X-2y=2
-6(17+4y) - 2y=2
-102-24y-2y=2
-26y=2+102
-26y=104
y= -104/26
y= -4

x=17+4y
x=17+4•4
x=17+16
x=33

Which number satisfies the inequality 9h + 15 > 55?
zalisa [80]

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

                                            9h + 15 > 55

Subtract  15  from each side:          9h > 40

Divide each side by  9 :                  <em>  h > 40/9</em>

Any number greater than (4 and 4/9) satisfies the inequality.

AlekseyPX

Answer:

The pack of 12 pencils for 298 is better as it has a lower unit price.

Step-by-step explanation:

To be able to find the answer, you have to calculate the unit price for each brand by dividing the price of the pack by the number of pencils in the pack.

-298/12=24.83

-499/18=27.72

According to this, the answer is that the pack of 12 pencils for 298 is better as it has a lower unit price.
