The sum of three consecutive even numbers is 138. What is smallest of the three numbers ?

Let the three consecutive even numbers be: n

n + 2 and n + 4

Therefore: n + n + 2 + n + 4 = 138

Combine like terms: 3n + 6 = 138

3n + 6 - 6 = 138 - 6

6 - 6 = 0

138 - 6 = 132

3n = 132

Divide each side by 3

3n/3 = 132/3

n = 44

Therefore the three consecutive even numbers are: 44, 46 and 48

Check: 44 + 46 = 90 + 48 = 138

Answer: 44

Hope this helps!

Write an equation in point-slope form for the line.<br> (1,3) <br> (0,1)<br> m=4
Anna [14]

Given coordinates (1,3) and (0,1).

In order to find the equation of line, we need to find the slope between given coordinates.

We know slope formula,

m= \frac{y2-y1}{x2-x1}

We have (x1,y1) = (1,3) and (x2,y2) = (0,1).

Plugging values of x1,y1,x2 and y2 in slope formula, we get

m=\frac{1-3}{0-1}

Simplifying top and bottom of the fraction we got for slope

m=\frac{-2}{-1}=2

We got slope m=2.

We are given second point (0,1), where x-coordinate is 0 and y-coordinate is 1.

y-intercept is a point on y-axis, where x=0.

Therefore, y-intercept = 1.

Now, applying slope-intercept form of the linear equation

y=mx+b, where m is the slope and b is y-intercept.

m=2 and b=1.

Plugging values of m and b in slope-intercept form, we get

y=2x+1.

Therefore, point-slope form for the line is y=2x+1.

An edging was placed around a circular garden. How long was the edging if the radius of the garden was 3m. Use TT = 3.14
Tom [10]
Edging is 18.84m. to find the edging you  must do the radis times 2, then that answer by pi (3.14). So you do 3x2=6, then 6x3.14=18.84m
