She actually has 8.36, so I think it's not reasonable to say 8.50, much closer to 8....my opinion

To find out how much is on her gift card we take off the muffins from the 14.48 on her gift card.

5 * 1.02 = 5.10 she spent on the gift card

14.48 - 5.10 = 9.38 left on her gift card

8.50 is less than 9.38, but I don't think it is unreasonable since she knows she would have that amount on her gift card.  Though I would say 9 dollars would be more reasonable.

Use complete sentences to explain how you could use a number line to explain why 2 < 3 < 5. Please. :D
Svetach [21]
Two is less than three which is also less than 5.


When put into a number line from 0 to 10, it shows that 2 is closest to 0 while 5 is closest to 10 and three, will be in between 2 and 5. This shows that as you go from 2 to 3, the number increased and, it continues to increase when you go from 3 to 5. This shows that 2 is less than 3 and 3 is less than 5.

Solve by combining equations <br> PLS HELP!<br> 3x - 2y = 12<br> -3x+8y= -6
andreyandreev [35.5K]

3x−2y=12;−3x+8y=−6

Step: Solve3x−2y=12for x:

3x−2y=12

3x−2y+2y=12+2y(Add 2y to both sides)

3x=2y+12

3x

(Divide both sides by 3)
