Every counting number is a rational number true or false
ra1l [238]
<h3>Answer:  True</h3>

Reason:

The counting numbers, aka the set of natural numbers, is the set {1, 2, 3, 4, 5, ...} which is the set of positive integers

A value like 5 is the same as 5/1, which shows it is rational.

A rational number is any fraction of two whole numbers (eg: 2/3 and 4/7). The denominator cannot be zero.

Since we can rewrite the 5 as 5/1, it can be done with any counting number to show the natural numbers is a subset of the rational numbers.

Any counting number is rational, but not the other way around.

PLS HELP Anna buys bananas and apples. She buys 2 more apples than twice the number
Alecsey [184]

Answer:

You have to put this in a bar model yourself so convert it later

She bought 10 apples

Step-by-step explanation:

3x + 2 = 14

why i did this

because she bought 2 times the amount of bananas, it should be x + 2x = 3x

then i added two because she bought two extra apples

so 3x+2 = 14

subtract 2

3x = 12

x = 4

So now we substitute x in apples

2x +2 = # of apples

8 +2 = 10

check

10 - 2 = 8

8/2 = 4

4 = # of bananas
