Step-by-step explanation:

-7Q + 6 + 5Q = 15 - 7

Q=-1

3 (P+5) + P = 3(2+P)

P=-3

2(A+4) + 6A = 2(2 + 3A)

A=-2

Answer:

11/18.

Dan is 8.

Step-by-step explanation:

The initial fraction is

x / 2x-4

Adding 3/3 we have

x+3 / 2x-1 = 2/3

Cross multiply:

3(x+3) = 2(2x-1)

3x + 9 = 4x - 2

9 + 2 = 4x - 3x

11 = x,

So the original fraction was 11 / 2(11) - 4

= 11/18.

If Dans age is d then Lois's age = 4d.

So 4d + d = 40

5d = 40

d = 8.

So Dan is 8 years old.

What is an equation of the line that passes through the points (6, 8) and (−3,2)?

ycow [4]

<h3><u>Explanation</u></h3>

Calculate the slope by using rise over run with two given coordinate points.

$m = \frac{8 - 2}{6 - ( - 3)} \\ m = \frac{6}{6 + 3} \\ m = \frac{6}{9} \\ m = \frac{2}{3}$

The slope is 2/3.

Slope-intercept form

$y = mx + b$

where m = slope and b = y-intercept. Substitute the value of m in slope-intercept form.

$y = \frac{2}{3} x + b$

Substitute one of two coordinate points in the slope-intercept form.

I will use (-3,2) instead.

$2 = \frac{2}{3} ( - 3) + b \\ 2 = - 2 + b \\ 2 + 2 = b \\ 4 = b$

The y-intercept is (0,4). Then rewrite the equation by substituting the b-value and slope in slope-intercept form.

$y = \frac{2}{3} x + 4$

<h3><u>Answer</u></h3>

<u> $\large \boxed{y = \frac{2}{3} x + 4}$ </u>
