Reduce to simplest form. - 3/5 + 1/3
Pani-rosa [81]

Answer: -4/15

Step-by-step explanation: To add these two fractions together,

we start by finding their <em>Least Common Denominator</em> (LCD).

Since our denominators of 5 and 3 have no factors in common,

our least common denominator is 5 · 3 or 15.

In order to get a denominator of 15 in each fraction,

we multiply top and bottom of the first fraction by 3

and top and bottom of the second fraction by 5.

That gives us -9/15 + 5/15 which simplifies to -4/15.

As your last step, make sure that the fraction

that you end up with doesn't reduce.

In this case, -4/15 does not reduce but watch out for this last step.

Which polygon is a concave octagon?
Bezzdna [24]

The polygon in option 3 is not octagon at all, it is heptagon (or 7-sided polygon).

A convex octagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°.

When some internal angle is greater than 180°, it is concave.

In option 2 you can see that one angle is pointing inward, then this octagon is concave.

Answer: correct choice is B.

green pepper, onion, tomato

= 2x, 5x, 9x

Number of cups = 96

therefore 2x + 5x + 9x = 96

16x=96

x= 96÷16 = 6

Onion = 5x

therefore answer = 6 x 5 = 30

C. 30 is the correct answer :)
