Marianne sold 3 times as many T-shirts as Brayan. Marianne sold 36 T-shirts. Write and solve an equation to find how many T-shirts Brayan sold.​

x = 12

Step-by-step explanation:

Let Number of Shirts sold by Marianne be equal to = 3x = 36

Let Number of Shirts sold by Brayan be equal to = x = ?

Solving the simple equation,

3x = 36

x = 36/3

x = 12

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
