Answer:
55.25 = x
Step-by-step explanation:
3x - 161 = 7x - 382
Balance method:
7x- 3x = -161 + 382
4x = 221
Divide to find x:
221/4 = x
55.25 = x
1 inch is the same as 8/8
Use this to solve
8/8 - 3/8 = 5/8
The 1 inch button is 5/8 longer than the other button. Hope this helps!
Step-by-step explanation:
the option with the isoceles triangles can NOT be just of that proof, because nowhere is it defined or proven that there is or are isoceles triangles involved. even though the picture looks like it, but that does not mean anything for the formal proof.
actually, this proof is the same (and is also valid) for non-isoceles triangles.
Ok you would have to multiply the 11 by 3 then you should get your answer of 33m.
