Jamie's age is n. (given)

Brian's age is 2n. (given)

Half of Brian and Jamie's present age is (n +2n)/2 = 3n/2.

Let m represent Morgan's age now. Then

... m + 8 = 2 + 3n/2 . . . . . in 8 years, Morgan's age will be 2 more than ...

Subtract 8 to find Morgan's present age:

... m = 3n/2 - 6 . . . . Morgan's present age

Steps for solving 3x+18=54 are shown explain how step 1 helps solve the equation
Dennis_Churaev [7]

Answer:

The answer is x=12.

Step-by-step explanation:

First, to solve this equation you need to isolate the x variable. To isolate the variable, you must, subtract the other term from both sides. Subtracting 18 from both sides, you are left with 3x = 36. Since 3 times x = 36, dividing both sides by 3 gets you, x=12.

Write a linear equation that passes through the two points (-6, -7) and (3, -4).
Phantasy [73]

linear equation that passes through the two points (-6, -7) and (3, -4) is y=\frac{1}{3}x-5

Step-by-step explanation:

We need to write the equation that passes through the two points (-6, -7) and (3, -4).

The equation can be written is point slope form.

The standard form of point slope equation is:

y=mx+b

where m is the slope and b is the y-intercept

Finding slope m:

Slope can be found by using formula:

slope = \frac{y_{2}-y_{1}}{x{2}-x_{1}} \\Where\,\, y_{2}=-4,y_{1}=-7,x{2}=3,x_{1}=-6\\slope =\frac{-4-(-7)}{3-(-6)}\\slope=\frac{-4+7}{3+6}\\slope=\frac{3}{9}\\slope=\frac{1}{3}

So, slope is \frac{1}{3}

Now finding y-intercept b

Putting slope \frac{1}{3} and point(-6,-7)

y=mx+b\\x=-6,y=-7,m=\frac{1}{3} \\-7=\frac{1}{3}(-6)+b\\-7=-2+b\\b=-7+2\\b=-5

So, value of b is -5

Putting values to find the equation:

y=mx+b\\m=\frac{1}{3} and b=-5\\y=\frac{1}{3}x-5

So, linear equation that passes through the two points (-6, -7) and (3, -4) is y=\frac{1}{3}x-5

The triangles are similar. What is the value of x?
jok3333 [9.3K]
Given that the two triangles are similar:
\frac{7}{28} =  \frac{25}{6x + 28}
\frac{1}{4} = \frac{25}{6x + 28}
6x + 28 = 4 x 25
6x + 28 = 100
6x = 100 - 28
6x = 72
x = 12
