Equations with variables. explain it to me.

Equation: 10x-12=6x-6

X: 3/2 or .5

Perimeter of square and triangle are both 3.

Step-by-step explanation:

Square:

4(2.5x-3) {The four represents the amount of sides}=

10x-12

Triangle:

3(2x-2)=

6x-6

Since they have the same perimeter the equation is

10x-12=6x-6

10x-6x=12-6

4x=6

x=1.5

Square pt 2:

4(2.5(3/2)-3)=

4(3.75-3)=

4(0.75)=

3

Triangle pt 2:

3(2(3/2)-2)=

3(3-2)=

3(1)=

3

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000
