Answer:
6/35
Step-by-step explanation:
change 2/5 to 14/35 so the denominators are even.
after that you get -8/35+14/35
then you get 6/35
7 1/4 + 5 3/5
First, you need a common denominator to add the two. 20 will work.
4x5=20, so we have to also multiply 1 by 5.
4x5=20, 1x5=5
5x4=20, so we have to also multiply 3 by 4.
5x4=20, 3x4=12
And now we put the fractions back in.
7 5/20 + 5 12/20
And add them.
7 5/20 + 5 12/20 = 12 17/20
Now, we're supposed to reduce it to its lowest form.
Unfortunately, the fraction cannot be reduced, because 17 is a prime number, meaning there are no factors to it except one and itself.
Therefore, the lowest form of 12 17/20 is 12 17/20
Your answer is B, 12 17/20
Using the slope-intercept form, the slope is
2

Answer:x=53/6 and y=-55/6
Step-by-step explanation:
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6
