X=3. 33x-21x equals 12x. 24+12=36. 12x divided by 36 equals 3
Answer:
x=130, x=-77.5, x=1/3
Step-by-step explanation:
1st equation:
1/5x + 24 = 50
1/5x = 26
x = 26(5)
x = 130
2nd equation:
0.4x + 18=-13
0.4x = -31
x=-77.5
3rd equation:
3x - 5/6 = 1/6
3x = 1
x=1/3
Answer:
15 months

330+120=450, and 450 divided by 30 equals 15. Therefore, Sophia has saved $30 to her savings account every month for 15 months.
Answer:
16. 20, 25
17. 3, 4
18. 5, 7
19. 6.5, 5, 3.5, 2, 0.5
Step-by-step explanation:
The way you would solve this is by replacing the variable with an x-value, the answer would be the y-value.
F(x)=2x+8
G(x)=x-4
Plug g(x) into f(x)
F(g(x))=2(x-4)+8
Distribute
F(g(x))=2x-8+8
Simplify
F(g(x))=2x
