First answer: x = 3

How?

3x - 7 = 2

3x = 2 + 7

3x = 9

x = 9/3

x = 3

Second Answer:= x=5

How?

3 + 2x - (x + 1) = 3x - 6

-3x + 2x - x = -6 - 3 - 1

-2x = -10

x = 5

The Glitz Jewelry Kit contains round beads in 6 different colors plus 100 star-shaped beads.
Alinara [238K]

Answer:

False, it would actually be 106 beads. If this was a multiplication problem, that would also be false, because 6 times 100 is 600, not 350.

But let's attempt to make this statement true.

<u>First/Last step:</u><em> Find the missing beads.</em>

The missing beads are 144.

Why?

Because you must add 144 to reach 250, there is no other way but to multiply. In this case, because the key word is, "In all" we are adding.
