The price of a sweatshirt at a local shop is twice the price of a pair of shorts. the price of a t-shirt at the shop is $4 less than the price of a pair of shorts. brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 t-shirts for a total cost of $136.

19let w represent the price of one sweatshirt, t represent the price of one t-shirt, and h represent the price of one pair of shorts. write a system of three equations that represents the prices of the clothing.

20= solve the system. find the cost of each item.

Price of sweatshirt = $24

Price of t-shirt=$8

Price of shorts= $12

Step-by-step explanation:

Let

w be the price of one sweat shirt

t be the price of t-shirt

h be the price of shorts

The first statement is:  

The price of a sweatshirt at a local shop is twice the price of a pair of shorts.

w=2h    Eqn 1

Then,

The price of a T-shirt at the shop is $4 less than the price of a pair of shorts.  

t=h-4    Eqn 2

And

Brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 T-shirts for a total cost of $136.

3w+2h+5t=136  Eqn 3

Putting the value of w and t in equation 3

3w+2h+5t=136

3(2h)+2h+5(h-4)=136

6h+2h+5h-20=136

13h=136+20

h=156/13

h=12

So the price of pair of shorts is $12.

Putting the value of h in equation 1

w=2(12)

w=24

Price of sweatshirt is: $24

Putting the value of h in eqn 2:

t=12-4

t=8

Price of T-shirt is $8 ..  

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
