Answer:
5 per noun, 8 per verb
Step-by-step explanation:
start by defining what each variable is
v = n+3
v = 2n-2
substitute v for one of the equations above
n+3 = 2n-2
subtract n from both sides
3 = n-2
add 2 to each side
5 = n
so there are 5 flashcards per noun
substitute 5 in for n in both equations
v = 5+3
and
v = 2(5)-2
solve both equations
v = 8 and v = 8
so there are 8 flashcards per verb
A circle is 360 degrees, and there are 12 sections on a clock. Divide 360 by 12, which will get you 30. The hand moves 4 hours, so you would multiply 30 times 4 and get 120 degrees. I hope I helped!
