Six friends went to a basketball game. the price of admission per person was $x. four of the friends paid an extra $5 each for a souvenir t-shirt. write and simplify an expression that represents the total cost.

6x+20 or 2(3x+10)

Step-by-step explanation:

Six friends went to a basketball game and four people paid $5 extra for a t-shirt.  To find the total cost, multiply 6 by x and 4 by 5 this add them together:

6*x+4*5

6x+20, If needed you can factor this expression to:

2(3x+10)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
