Answer: 146

Step-by-step explanation:

If he only gets 20 at the end of the night, and not 20 per hour, then you would take 14 times 9, plus 20.

This, put into equation form, would be 14x +20. Then you'd put 9 in for x.

You would then get 146. Hope this helps!

Answer:

146

Step-by-step explanation:

Since John works for 9 hours and makes 14 an hour. You multiply 14 by 9 which equals 126. You add 20 from the tips to 126. This makes 146.

Is it possible for a number to be a rational number that is not an interger but is a whole number. Explain
mylen [45]

Whole numbers are a subset of integers, which in turn are a subset of rational numbers.

So, every whole number is an integer, and every integer is a rational number.

So, it is possible for a rational number not to be an integer. Think of any decimal number: 1.356 is a rational number, but it's not an integer.

On the other hand, if a number is not an integer, it can't be a whole number, because all whole numbers are integers.

4. Add one set of parentheses to make the expression equal
Sauron [17]

The expression that is equal to 2022 by adding a set of parentheses is 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12).

<h3>How to solve a long-expression problem?</h3>

In mathematics, parentheses are used to group a set of mathematical terms. In  a long-expression, like the one presented, using parenthesis implies:

  • The terms in the parentheses are solved separately from those outside the parentheses.
  • The terms in the parentheses are solved before solving those outside.
  • Moving the parentheses will affect the result of the whole expression.

Based on this, the expression that equals 2022 is:

  • 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

<h3>Let's solve it to prove this result</h3><h3 />
  • 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

First, solve the parenthesis first by dividing and then by adding.

  • 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (1 + 1)12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / 2

Now, let's solve this expression, the first step is to solve the multiplications.

  • 1728 + 144 + 144 + 12/2

Now, solve the division.

  • 1728 + 144 + 144 + 6

Finally, add everything.

  • 1728 + 144 + 144 + 6 = 2022

Kira runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?
SashulF [63]

Answer: She runs about 4.2 miles.

Step-by-step explanation:

6/50 = x/35

6*35 = 50*x

210 = 50x

50x = 210

x = 210/50

x = 4.2
