So x is a variable which is just <span>character representing a number. We want to find x. To do this we want to get X by itself on one side of the equation. In this case/ we just need to divide both side by -4. Whatever you do to one side, you must do to the other. This gives us X = -12. To check yourself just plug your answer back into the equation to see if its right. -4(-12) = 48. You have successfully solved for X.</span>
Answer:
Max is currently 12 years old.
Step-by-step explanation:
Zeke's current age = 8 years
Lets take Max's current age as 
years.
Then Max's age 3 years ago = 
Double Max's age 3 years ago = 
Double Max's age 3 years ago + Zee's current age = 26
⇒ + 
= 
=
=
(Simplifying the brackets)
=
=
So Max's current age is 12 years.
Step-by-step explanation:
f(x) = 4x + 5, g(x) = 9x − 4
(f-g)(x) = f(x) -g(x)
=4x+5-9x+4
=-5x+9
=9-5x
Answer:
49.12 ft^2
Step-by-step explanation:
The triangle:
Area = 1/2 * base * height
= 1/2 * 6 * 8
= 24
The semicircle:
Area = 1/2 * 3.14 * 4^2
= 25 .12
Total area = 24 + 25.12
= 49.12 fT^2
