0.25r-0.125+0.5r=0.5r
0.75r-0.125=0.5r
-0.125= -0.25r
r=0.5
This is the distributive property. You take what is outside of the parenthesis and DISTRIBUTE it inside the parenthesis.
Y^-5
x^-5
because you have to put together all the x and then put all the y's together
X = 4/15 or 0.26
First add the numbers on the left side of the equation.
0.72 = 0.8 - 0.3x
Then move the variable to the left as well.
0.3x + 0.72 = 0.8
Move the constant to the right by subtracting.
0.3x = 0.8 - 0.72
Subtract the numbers
0.3x = 0.08
Divide both sides by 0.3.
And that should yield your answer.
Hope this helps. ^^
Answer:
x+y-10 -1
Step-by-step explanation:
if x is 3 and y is 6 then 3+6= 9
9-10=-1
