Answer:
x = 1
Step-by-step explanation:
5 x (2x - 8) + 15 = -15 Multiply 5 by 2x and -8
10x - 40 + 15 = -15 Add -40 and 15
10x - 25 = -15 Add 25 to both sides
10x = 10 Divide 10 by 10
x = 1
Answer: X=3
Step-by-step explanation:
This triangle has a centroid which means the line is 2/3 and 1/3.
3x+1= 2(2x-1)
3x+1= 4x-2
x=3
Lets x and y are the value of two numbers.
x + y = 16
x - y = 2.4
If x + y = 16 then x = 16 - y
Substitute x = 16 - y into x - y = 2.4
16 - y - y = 2.4
16 - 2y = 2.4
2y = 13.6
y = 6.8
x = 16 - y
x = 16 - 6.8
x = 9.2
Answer:
The value of two numbers are 9.2 and 6.8
Plug in numbers to make the equations work!
