Evaluate the equation 2L+6=6L-10

Answers

Answer:

2

Step-by-step explanation:

2L + 6 = 6L - 10                      Add 10 to both sides

2L + 6 + 10 = 6L                     Combine the left.

2L + 16 = 6L                           Subtract 2L from both sides

16 = 6L + 2L                           Combine the right    

16 = 8L                                   Divide by 8

8L = 16

8L/8 = 16/8

L = 2

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$77. A season ski pass costs ​$450. The skier would have to rent skis with either pass for ​$20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily​ passes?

Answers

Answer:

5

Step-by-step explanation:

Given:

Daily pass = $77Season ski pass = $450Skis = 20

77 + 20 = 97

450 + 20 = 470

Keep multiplying 97 with random numbers until it passes 470.

97 × 4 = 388

97 × 5 = 485

So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.

Answers

Answer:

s=5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

s=5

Answer:

s = 5

Step-by-step explanation:

1.52(s + 3) − 2.61 = 9.55

solve the brackets first

1.52s + 4.56 − 2.61 = 9.55

1.52s + 1.95 = 9.55

1.52s = 9.55 -  1.95

1.52s = 7.6

s = 7.6 / 1.52

s = 5

Let's Cross-Check

1.52 (5 + 3) − 2.61

7.6 + 4.56  − 2.61

7.6  + 1.95

= 9.55

Step-by-step explanation:

[tex]here \: b \: is \: the \: mid \: point \\ so \: ab = bc \\ 10x - 17 = 6x + 11 \\ x \: terms \: togather \\ 10x - 6x = 11 + 17 \\ 4x = 28 \\ x = \frac{28}{4} \\ x = 7 \\ thank \: you[/tex]

So on this line we got points A, B ,and C. These points are all equally distanced from each other. So line AB would have to equal to line BC. And line AB plus line BC would equal line AC.
We are given that line AB is 10x-17, with x as the unknown variable. Line BC is 6x+11. Line AB is equal to Line BC. Now we need to use that information to find x, so we’ll set up the equation.
Line AB=Line BC
10x-17=6x+11
Minus 6x to both sides (like terms)
4x-17=11
Add 17 to both sides (like terms)
4x=28
Divide both sides by 4
x=7
