Coach smith is buying equipment for his soccer team. he has 11 players and each player needs three uniforms, two shin guards, one ball, and two pairs of cleats write an algebraic expression to represent this situation.

The algebraic expression to represent this situation is :

Explanation

Suppose, the cost of a uniform is , cost of a shin guard is , cost of a ball is and cost of a pair of cleat is

Each player needs three uniforms,two shin guards,one ball,and two pairs of cleats. So, the total cost for one player

Thus, the total cost for 11 players will be:

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
