Answer:

Robert is 17 years old

Kent is 13 years old

Step-by-step explanation:

Alright, let's say that Robert is X years old, and Kent is X - 5 Years old, since he is 5 years younger. Since their ages together add up 39 years old, set these values next to one another.

x + x + 5 = 39

Add Like Terms

2x + 5 = 39

Cancel out the 5

2x = 34

Divide by 2

x = 17

With this, x is 17. This means that Robert is 17 years old since his age was x. With Kent he is 13 years old since 17 - 5 = 13.

Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2
nlexa [21]

Answer:

Yes!

The solution to the equation is n = 2

Step-by-step explanation:

Given the equation

4\left(n\right)-3=-2\left(n\right)+9

remove the parentheses

4n-3=-2n+9

Add 3 to both sides

4n-3+3=-2n+9+3

Simplify

4n=-2n+12

Add 2n to both sides

4n+2n=-2n+12+2n

Simplify

6n=12

Divide both sides by 6

\frac{6n}{6}=\frac{12}{6}

Simplify

n=2

Therefore, the value of n = 2.

Hence,

Yes!

The solution to the equation is n = 2

Through (2,0) slope = -5/3 write the slope intercept of the equation
babunello [35]

For this case we have that the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

In this case we have the following data:

m = - \frac {5} {3}\\(x, y) :( 2,0)

Then, the equation is of the form:

y = - \frac {5} {3} x + b

We find "b" replacing the point:

0 = - \frac {5} {3} (2) + b\\0 = - \frac {10} {3}\\b = \frac {10} {3}

Thus, the equation is:

y = - \frac {5} {3} x + \frac {10} {3}

Answer:

y = - \frac {5} {3} x + \frac {10} {3}
