Answer 8

104

Answer 9

Right. so the right side of the equation will be 104.

Left side:\[2x+36+40-36-40\]What does that equal?

Answer 10

72?

Answer 11

That's just 2x, right?

We had \[2x+36+40 = 180\]We subtracted 36 and 40 from both sides:
\[2x+36+40-36-40 = 180-36-40\]
\[2x+\cancel{36}+\cancel{40}-\cancel{36}-\cancel{40} = 104\]\[2x=104\]Can you solve that for \(x\)?

Answer 12

no

Answer 13

No? What number, doubled, gives you 104?

Answer 14

i dont know

Answer 15

What number is half of 104?

Answer 16

i dont know omg

Answer 17

Can you divide 104 by 2?

Answer 18

If you had 4 quarters and 2 pennies, you would have 102 cents. How much would half of that be?

Answer 19

52

Answer 20

Right.

\[2x = 104\]Divide both sides by 2
\[\frac{2x}{2} = \frac{104}{2}\]\[\frac{\cancel{2}x}{\cancel{2}} = 52\]\[x=52\]

Answer 21

so the answee is 52

Answer 22

Yes. Even though I gave you the wrong coin problem :-)

Answer 23

(should have been 4 quarters and 4 pennies = 104, 2 quarters and 2 pennies = 52, but you got the answer we needed)

Answer 24
