One tenth of 200 is 1/10 x 200 = 200/10 = 20
20 is your answer.
Distribute first so
2x-x+2=2-x+1
Combine like terms so
x+2=3-x
Get terms on the same side so
2x+2=3
Subtract 2
2x=1
Divide
X=1/2 or .5
Answer:
The scale Factor is 1/3
Step-by-step explanation:
BTW Hi
Plugging directly into the combination formula, the answer is 
where we have cancelled out common factors.
Answer:
x = 1
y = 3
Step-by-step explanation:
We can solve this problem by inputting the second equation into the first equation by replacing the y variable with the second equation.
x + 3y = 10
y = x + 2
x + 3(x + 2) = 10
Now, distribute three with x and 2
3 * x = 3x
3 * 2 - 6
x + 3x + 6 = 10
4x + 6 = 10
Subtract 6 from both sides
4x = 4
So, x = 1
Solve for y by replacing x in the second equation with 1.
y = 1 + 2
y = 3
