Answer:

-14k - 14

Step-by-step explanation:

1) Begin by distributing the 5, located outside of the parentheses.

2) Distributing is done by taking the number outside the parentheses and multiplying it with the numbers inside.

3) 5 * -3.4 5 * -7

4) After distributing, set up the numbers together so you are able to combine the like terms.

5) -17k -35 + 3k + 21

6) In this particular expression, the like terms are the integers and whole numbers, as well as the coefficients which contain the same variable.

7) -35 + 21 + -17k + 3k

8) In this step, combine the like terms from the expression above in step 7, use step 6 as a reference. -14 - 14k

9) Coefficents are always prioritized from a greatest to least order, therefore the simplified expression would be -14k - 14.

Which statement is true?

Lelu [443]

Answer:

The statement that is true is:

A debt of $17 is a larger value than a debt of $20.

Step-by-step explanation:

Let us look at the statements one after the other to determine if they are true or not:

1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$

2) One half an apple is equivalent to 8 fourths apples:

one half an apple = $\frac{1}{2}\ of\ an\ apple$

8 fourths of an apple = $\frac{8}{4} = \frac{2}{1}\ of\ and\ apple$ . Therefore, one half of an apple is not equivalent to 8 fourth of an apple.

3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:

8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009

4) $\frac{2}{3}\ below\ zero$ is a lower temperature than 6 below zero:
