4=2.25x add 2x on both sides
1.78=x subtract 2.25 on both sides
Answer:
To find volume of a tent this would be your formula:
start by taking the base of the triangle on your tent typically located in the front
1/2 (height) (width) to get your area (DONT SKIP THIS STEP)
Then take your area you just calculated and do
(area) (length)
Let me give you an example:
in the picture below
height: 3 cm
length: 8 cm
Width: 12 cm
Next do your first formula:
1/2 (3)(12)= 18 cm
(Calculation of one face)
then your second:
(18)(8)= 144 
Hopefully this guide helped you sorry i couldn't answer your question without a picture!

Simplifying
0.4x + -2.5 = 1.3x + 4.7
Reorder the terms:
-2.5 + 0.4x = 1.3x + 4.7
Reorder the terms:
-2.5 + 0.4x = 4.7 + 1.3x
Solving
-2.5 + 0.4x = 4.7 + 1.3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1.3x' to each side of the equation.
-2.5 + 0.4x + -1.3x = 4.7 + 1.3x + -1.3x
Combine like terms: 0.4x + -1.3x = -0.9x
-2.5 + -0.9x = 4.7 + 1.3x + -1.3x
Combine like terms: 1.3x + -1.3x = 0.0
-2.5 + -0.9x = 4.7 + 0.0
-2.5 + -0.9x = 4.7
Add '2.5' to each side of the equation.
-2.5 + 2.5 + -0.9x = 4.7 + 2.5
Combine like terms: -2.5 + 2.5 = 0.0
0.0 + -0.9x = 4.7 + 2.5
-0.9x = 4.7 + 2.5
Combine like terms: 4.7 + 2.5 = 7.2
-0.9x = 7.2
Divide each side by '-0.9'.
x = -8
Simplifying
x = -8
Answer:
Step-by-step explanation:
First write a point-slope equation y−y1=m(x−x1) , where (x1,y1) is the given point, (4,2) , and m is the slope, −3 . For graphing, you can convert to the slope-intercept form, y=mx+b , by solving for y , where m is the slope and b is the y-intercept.
