Draw lines to show the correct order of the steps that you could take to solve the equation 2/5(x+5/2) = 27 (the 2/5 and 5/2 are fractions)

x = 65

Step-by-step explanation:

Step 1

multiply both sides by 5 to eliminate the fraction

2(x + ) = 135

Step 2

Distribute the parenthesis

2x + 5 = 135

Step 3

Subtract 5 from both sides

2x = 130

Step 4

Divide both sides by 2

x = 65

These would be the steps I would take, however the steps indicated in the question would be

step 4 → step 1 → step 2 → step 3

at least two

step-by-step explanation:

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
