T-shirt 6 10
hats 4 7
Let x = t-shirts, y = hats
6x + 4y = 2,000
10x + 7y = 3,375
4y = 2000 - 6x
y = 2000/4 - 6x/4
y = 500 - 3x/2
10x + 7y = 3,375
10x + 7(500 - 3x/2) = 3,375
10x + 3500 - 21x/2 = 3,375
10x - 10.5x = 3,375 - 3500
-0.5x = -125
-0.5x / -0.5 = -125/-0.5
x = 250 shirts
They will need 250 shirts.
DVD weighs 6lbs and game machine weighs 14lbs, so in this case A
in my mind this is what i did...
3(gameMachines) + 5(DVD) = 72lbs
3(gameMachine) + 1 (DVD) = 48lbs
when you subtract, since there is the same number of game machines, they cancel out and your left with
4(DVD) = 24
1 DVD = 6
then just fill in DVD in one of the equations to get the weight of gameMachine
3(gameMachines) + 5(6) = 72lbs
3(gameMachines) = 42
gameMachine = 14

Answer:
(a) m<3 = 103 degrees
(b) m<4 = 77 degrees.
Step-by-step explanation:
A: The sum of the measures of all three interior angles in a triangle always is 180 degrees. Knowing this, we add the two known interior angles, 20 and 57, then subtract that from 180 to get 103 degrees.
B: The measure of an exterior angle is the sum of the two opposite interior angles. So, we add 57 and 20 to get the m<4 = 77 degrees.
