Pete and his sister, Sophie, play the game Space Mission Commander on their video game console. Pete has already completed 27 mi
kondor19780726 [428]

Step-by-step explanation:

Pete has already completed 27 missions. Pete plans to complete 3 missions per week

Let x represents weeks

Games completed = 3x + 27

Sophie has only completed 13 missions. Sophie plans to complete 5 missions per week.

Games completed = 5x + 13

3x + 27 = 5x + 13

27 - 13 = 5x - 3x

2x = 14

x = 7

By the seventh week, they would have completed equal number of games,

Felix wrote several equations and determined that only one of the equations has no solution. Which of these equations has no sol
lara [203]

Answer:

3(x-2)+x=4x+6

Step-by-step explanation:

case 1) we have

3(x-2)+x=4x-6

Solve for x

3x-6+x=4x-6

4x-6=4x-6

0=0 ----> is true for any value of x

therefore

The equation has infinite solutions

case 2) we have

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

3x-6+x=2x-6

4x-2x=-6+6

2x=0

x=0

case 3) we have

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

3x-6+x=3x-3

4x-3x=-3+6

x=3

case 4) we have

3(x-2)+x=4x+6

3x-6+x=4x+6

4x-4x=6+6

0=12 ------> is not true

therefore

The equation has no solution

Solve for x.<br><br> −4≤11−3x<br><br> x≥5<br><br> x≥−5<br><br><br> x≤5<br><br> x≤−5
Fofino [41]

Isolate the x. Do the opposite of PEMDAS.

−4 ≤ 11 −3x

First, subtract 11 from both sides

-4 (-11) ≤ 11 (-11) - 3x

-4 (-11) ≤ - 3x

-15 ≤ - 3x

Isolate the x. Divide -3 from both sides. Remember to flip the sign.

(-15)/-3 ≤ (-3x)/-3

-15/-3 ≤ x

5 ≥ x

x≤5 is your answer

hope this helps
