Simplify. 3/5+(-1/4)÷7/10

Answer:

1/10

Step-by-step explanation:

There are three simple fractions in this problem:  3/5, -1/4 and 7/10.  Rules of order require that the division (-1/4) divided by 7/10 be carried out first; the correct product is  -10/28, or -5/14.  Then we have 3/5 + (-5/14).

Here the LCD is 70.  Then 3/5 + (-5/14) becomes 42/70 - 35/70, which simplifies to 1/10.

What are both of the ranges
MArishka [77]

Answer:

0.8 < x < 16.8

Step-by-step explanation:

The third side of the triangle is always less than the other two sides combined. I think of it like if it was greater than the other two sides added, there would be no triangle- it'd be a line.

The other rule is that it has to be greater than the difference between the two lines.

I hope this helped!

Two numbers total 63 and have a difference of 31. Find the two numbers
Anastaziya [24]

Answer: 47 and 16

Step-by-step explanation:

- Make Two Equations

x + y = 63

x - y = 31

- Set one of the equations equal to one of the variables

x + y = 63

x = 31 + y

- Substitute the equation back into the other one

(31 + y) + y = 63

31 + 2y = 63

2y = 32

y = 16

- Substitute the answer back into the equation

x + y = 63

x + 16 = 63

x = 47
