Answer:
2 over 5
Step-by-step explanation:
Common ratio =
7/ (35/2) = (14/2) / 7
Our answer became 2/5
Answer:
No solution
Step-by-step explanation:
The given equations are :
9x-3y=-6
3x-y=2.....(1)
5y=15x+10
5y-15x=10
or
y-3x=2 .....(2)
Equations (1) and (2) shows that the lines are parallel. We know that for parallel lines, there is no solution.
Answer:
x = 7.2
Step-by-step explanation:
5x - 36 - 11x = 3x + 36 + 3x
add like values together:
16x - 36 = 6x + 36
add 36 to each side:
10x = 72
divide by 10 to get x alone:
x = 7.2
Answer:
21
Step-by-step explanation:
If x was more than 1, then it would be impossible because fx would have to be even, but 4x+3 would be odd. Therefore, x must equal 1, and f must equal 7. This means that 3f=21
