Ksju [112]
Jason is buying 2 hats and 3 scarves for each of his 4 children

so he is actually buying 8 hats and 12 scarves.

a hat costs 8.50 and a scarf costs 5.50

so you put it into a equation

8.50(h)+5.50(s) = P     h = hat, s = scarf, P = pay

8.50(8)+5.50(12) = P

68 + 66 = P

P = 134

hope this helps

I need the answer for this please
Jlenok [28]

Since T is the midpoint of PQ, this means that PT and TQ must be equal to each other. Make them equal to each other in an equation.

PT = TQ

4x + 2 = 7x - 7

  • Subtract 2 from both sides.

4x = 7x - 9

  • Subtract 7x from both sides.

-3x = -9

  • Divide both sides by -3.

<u>x = 3</u>

  • Now substitute 3 for x into PT.

PT = 4(3) + 2

  • PT = 12 + 2
<h3>PT = 14</h3>
