For this case we have the following expression:
 4x - 2x + 8 = 6 (x + 4)
 The first step is:
 4x - 2x + 8 = 6x + 24
 The first step is, correct.
 However, the justification "Combine like terms" is NOT correct.
 The correct justification is:
 Distributive property of multiplication.
 Answer:
 
A step that has an incorrect justification is:
 
Step 1

I theater sells tickets for a concert. Tickets for lower-level seats sell for $35 each and tickets for upper-level seats sell fo
lora16 [44]

Let X= the number of tickets sold at $35 each

Let 350 -X = the number of tickets sold at $25 each

The number of tickets sold for each type will be computed as follows:

X(35)+(350-X)25=10250

35X+8750-25X=10250

10X=10250-8750

X=1500/10

X=150 the number of tickets sold at $35 each

350-150 the number of tickets sold at $25 each

To recheck:

150(35)+200(25)

5250+5000

10250

How can you use similar triangles to find a missing measurement?
Vlad1618 [11]

Answer:

By comparison of the sides.

Step-by-step explanation:

If triangles are similar, that means their angles are equal and sides are proportional.

If you already have a proportion of two corresponding sides between triangles, then use that proportion and set it equal to a side you already know the measurement to. Hopefully that side is corresponding to your missing measurement, and you can then solve it.
