Give an example of this when adding two rationalnumbers with different signs and provide the product.
kolezko [41]

ANSWER:

\begin{gathered} \frac{4}{5}+-\frac{8}{3}=-\frac{28}{15} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{32}{15} \end{gathered}

STEP-BY-STEP EXPLANATION:

Rational numbers are all numbers that can be expressed as a fraction, that is, as the quotient of two whole numbers.

Therefore, an example would be:

\begin{gathered} \frac{4}{5}\text{ and - }\frac{8}{3} \\ \text{adding} \\ \frac{4}{5}+-\frac{8}{3}=\frac{4}{5}-\frac{8}{3} \\ \frac{4}{5}-\frac{8}{3}=\frac{4\cdot3-5\cdot8}{5\cdot3}=\frac{12-40}{15}=-\frac{28}{15} \\ \text{ product} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{4\cdot8}{5\cdot3}=-\frac{32}{15} \end{gathered}

The model represents an equation. What value of x makes the equation true?
kirill [66]

Answer:

<h3>B. 9/4</h3>

Step-by-step explanation:

According to the diagram, there are 5 x's in and 8 of negative 1 in the left hand side of the equation. This is represented mathematically as;

= 5x+8(-1)

= 5x - 8 .............. 1

In the right hand side, there are 3 of -x's and 1 in 10 places. This is also expressed as;

= -3x+1(10)

=  -3x+10 ............ 2

Equate 1 and 2 and find x

5x-8 = -3x+10

add 7 to both sides

5x-8+8 = -3x+10+8

5x = -3x+18

add 3x from both sides

5x+3x = -3x+18+3x

8x = 18

x = 18/8

x = 9/4

Hence the value of x that makes the equation true is 9/4
