Greatest common factor=gcf
least common multule=lcm
with 12 and 16
factors of 12=2 times 2 times 3
factors of 16=2 times 2 times 2 times 2
greates common factor is 2 times 2=4
least common multiule means all factors combined minus repeats or 2 times 2 times 2 times 2 times 3=48
Answer:
x = 98°
Step-by-step explanation:
We know that in a heptagon, there are 900°. <em>So</em>,
900 - (146 + 122 + 142 + 140 + 110 + 142)
We plug that into the calc and we should get 98 as our final answer!
1 down, means minus 1 from whole equation
moving 1 to left means add 1 to every x
reflecting across x axis means multiply every x by -1

Found the problem:
Item Cost Sales Price
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.
