Point B is the midpoint of line segment AC
so 2 * (AB) = AC
2(3x) = 5x + 21
6x = 5x + 21
x = 21
Answer: x= 26/3
Step-by-step explanation: Solve the rational equation by combining expressions and isolating the variable x.
Let's solve your equation!
4 + 2x
/6x = 12/5x
2x + 4/6x= 12/5x + 2/15
Multiply all terms by x and cancel:
- 2x + 4/6= 12/5
- 1/3x + 2/3 = 2/15x = 2/15x + 12/5 - 2/15x (Subtract 2/15x from both sides)
- 1/5x + 2/3 = 12/5
- 1/5x + 2/3 -2/3 = 12/5- 2/3 (subtract 2/3 from both sides)
- 1/5x = 12/5
- Multiply both sides by 5
- Check all your answers,
- x= 26/3
It can be 9/2 or it can be 4½
Answer:
A. 4 1/2
Step-by-step explanation:
To solve this, let's isolate x
6 + (2/3)x = 9 1. Subtract by 6 on both sides
(2/3)x = 3 2. When dividing fractions, think of it as multiplying both sides by the reciprocal of the given fraction
x = (3/2)(3/1)
x = 9/2
x = 4.5
Answer:1/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
=(9-3)/(7-(-5))
=6/12
= 1/2
