Answer:
2x-15 < or = -23
Step-by-step explanation:
Let x be the number.
Twice that number is 2x. 15 less than that is -15.
2x-15 < or = -23
Your equation should be:
4 + 6x = 22
This is so because he only bought one movie, but he bought "some" video games. The variable x represents some in the problem.
Solve the equation.
4 + 6x = 22
Subtract 4 from both sides of the equation.
6x = 18
Divide both sides by 6.
x = 3
Marcus rented 3 video games.
Solution :
D. 4 + 6x = 22
B. 3 video games
Mean means average (no pun intended)
HOW TO FIND THE MEAN
so basically to find the mean let's say you have 4 terms x,y,z,t
to find the mean, add them and divide by the number of terms you have (4)
(x+y+z+t)/4=mean
so we have the numbers
46,38,53,34,27,54
6 numbers total
add then and divide by 6
(46+38+53+34+27+54)/6=252/6=42
answe ris 42
