On a game show, Celine is given the digits from 1 to 6 and has to use them to fill in a row with 2 spots. If the number formed is the correct price of the item displayed, she wins the item. Given that each digit can be used only once, how many 2-digit prices are possible?

30 Two digits prices are possible.

Step-by-step explanation:

Celine was given numbers from 1 to 6

so the possible numbers are 1, 2, 3, 4, 5, 6

And we need to make a two digit number using these digits by using them only once

Using the box method of permutation

So we will have total permutations = 6*5 = 30

Therefore 30 Two digits prices are possible.

a) 15/7

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
