Answer:

A.)  x=4,y=11

Step-by-step explanation:

Given Equations:

y = -2x + 19     Equation:1

y = x + 7         Equation:2

Solving Equation:2 for 'x'

x=y-7             Equation:3

Using Substitution method, Putting 'x' in Equation:1

                        y = -2(y-7) + 19\\y=-2y+14+19\\y=-2y+33\\y+2y=33\\3y=33\\\\y=\frac{33}{3}\\\\ y=11

Putting value of 'y' in Equation:3

                       x=y-7

                       x=11-7

                       x=4

x=4,y=11

State the rational number represented by each letter on the number line as a decimal.
Phoenix [80]

The rational number represented by the letter D is -43/100 and by the letter R is -46/100.

What is rational number?

A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

Here the number line is divided into 10 division with equal distance.

Each division is of the distance 0.01

So, the decimal number represented by letter D is -0.43 and by the letter R is -0.46.

To convert decimal number into rational number,

-0.43 = -43/100

-0.46 = -46/100

Therefore, the rational number represented by each letter on the number line as a decimal are D = -43/100 and R = -46/100.

Which equation is true? Explain your answer.
Liula [17]

Answer:

<h2>12/36</h2>

Step-by-step explanation:

1. Find if all of the fractions are equal to the other fraction next to them.

First, let's go with the denominator of all.

6/8 = 4/3

First of all, we can easily say that this is not right, since the fact that, 6 is less than 8, and 4 is greater than 3. That's just signaling that this can't be the answer.

3/5 = 8/10

10/5=2

8/3=??? (doesn't go into 8)

So, this one is also wrong

12/16 = 36/48

48/16=3

36/12=3

<h2>So hence, the last one or 12/16=36/48 is RIGHT.</h2>
