Malik used these steps to solve the system of equations. 2 x + 4 y = 20. 5 x minus 3 y = 11.

Step 1 6 x + 12 y = 60. 20 x minus 12 y = 44.
Step 2
Step 3 x = 4
Step 4 2 (4) + 4 y = 20. 8 + 4 y = 20. 4 y = 12. y = 3.
Step 5 The solution is (4, 3).

What needs to be done in step 2?
Divide both sides of the equations in step 1 by the same number to eliminate one variable.
Multiply both sides of the equations in step 1 by the same number to eliminate one variable.
Add the equations in step 1 to eliminate one variable.
Subtract the equations in step 1 to eliminate one variable.

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

answer:

idk

step-by-step explanation:

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
