How to add two fractions?

Let we have to add two fractions as:

(a_1)/(b_1) + (a_2)/(b_2)

Then we will find LowestCommon Multiple (LCM) of b_1 and b_2. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the finalresult of addition.

So, we're specified that:

  • Ruby ate 1/3 of a pizza
  • Angie ate 1/5 of the pizza

These 1/3 and 1/5 are parts of pizza.

If  we add those parts which is eaten, we will get the total part of the pizza eaten.

Thus, we get:

Total part of the pizza eaten = (1/3 + 1/5) of a pizza.

The least common multiple of 3 and 5 is 15, because:

3,6,9,12,15\n5,10,15

(see the multiples of 3 and 5. The first common number as both's multiple is the least number which is multiple of both, and is 15).

Thus, we get:

(1)/(3) + (1)/(5) = (1 * 5 + 1 * 3)/(15) = (8)/(15)

Thus, the amount of pizza that Ruby and Angie ate in all for this considered situation is given by: Option A: 8/15

What is the slope of a line parallel to the line -3x+5y=-10

Answers

This looks familiar, right? Like slope-intercept.

y=mx+b, where m is the slope.

Let's right it like that.

5y=3x-10 (add 3x to both sides, since we want to isolate the y.)

Now divide by 5, since - again - we want to isolate the y.

y= 3/5x-10/5 >>>> y= 3/5x-2

I think the slope is 3/5.

If the line happens to be parallel, the slope is the same. If perpendicular, it is opposite reciprocal. So if it was perpendicular, the slope would be -5/3.

The slope can be found re-writting the function in the general format s y=mx+n where m is known as slope. For this case:

-3x+5y=-10, trasponding the x term

5y=3x-10, dividing by 5

y=3x/5-10/5, solving finally have the general format:

y=3/5x-2

Then the slope is the number that precede the x unknow.

Solution. The slope is 3/5.
