Ron has 20 apples. he used 2/5 of the apples to make pies. how many apples did ron use for pies? explain .

20/5=4 (to find a fifth of 20 apples)
4x2=8 (to find what 2 fifths is)

He used 8 apples

The best way to do this one is by multiplication. If you have two dozens of eggs, you multiply two by a dozen to find out how many eggs you have: 2*12=24. Similarly, if you have two fifths of 20 apples, you multiply 2/5 by 20 to find out how many apples you have: (2/5)*20 = 8.

B.

Step-by-step explanation:

Well, we can use the following formula to find the x coordianate of the vertex  -b / 2a.

So let’s start with a)

-6 / 6

-1

A. is wrong because its vertex starts with -1.

b)

6 / 6

1

now that we have our x coordinate we can plug it into the equation to get our y.

3 - 6 - 3

So the y coordinate is -6.

Hence, the answer choice B.
