Answer:
-50 2/5.
Step-by-step explanation:
First subtract the whole numbers:
12 - 22 - 40
= -50.
Next the fractions:
1/5 - 2/5 - 1/5
= -2/5
So the answer is -50 2/5.
Answer:
x= 1/12
Step-by-step explanation:
Hi there!
2x + 1/2= 2/3
You're trying to solve for x. In order to do that you need x by itself. You have to subtract 1/2 from both sides. When you do this you get 2/3 - 1/2. You can't just subtract them, remember, you have to find a common denominator.
2/3
1/2
The common denominator for these two fractions would be 6. to get 2/3 to a denominator of 6, you have to multiply it by 2/2. To get 1/2 to have a denominator of 6, you have to multiply it by 3/3. You then get...
4/6
3/6
Now you can subtract straight across. 4/6-3/6 is equal to 1/6. Ply it back into the equation and you have 2x=1/6. Now you have to divide 2 on both sides. To do this you divide 2x by 2 to get x. Then, you divide 1/6 by two.
Remember when dividing fractions you must flip the second fraction and multiply. What I mean is...
1/6 divided by 2 is the same thing as 1/6 x 1/2. We flipped 2 to get 1/2 and then we multiply straight across. When you do this you get an answer of 1/12.
x=1/12
I really hope this helps! :)
Answer:
c(x + y) = a^2 + b^2
Step-by-step explanation:
All you have to do is cross multiply.
cx = a^2
cy = b^2
Add the equations.
cx + cy = a^2 + b^2
c(x + y) = a^2 + b^2
