Answer:
16 cards in 1 hour
Step-by-step explanation:
8 cards, 1/2 hour
16 cards in 1 hour
Make a proportion.
8/30min= x/60min
Solve the proportion by cross- multiplying.
30x=480
3x=48
x=16
Answer:
B) -9(2 + 3)
Step-by-step explanation:
As the answer choices are showing the backward process of distribution process, just divide common factors and bring them outside.
In this case, the factors of the following numbers are:
18: 1 , 2 , 3 , 6 , 9 , 18
27: 1 , 3 , 9 , 27
The largest common factor is 9. Divide -9 from both sides (since both of them share a negative sign, also factor out the negative sign):
(-18 - 27)/-9 = 2 + 3
B) -9(2 + 3) is your answer.

sorry thats all i know:(
Step-by-step explanation:
Radius = 6 inches
Arc lenght = 11pi inches
Degrees ?
Arc lenght = radius x angle in radians
A = r * a
Solving for a:
a = A/r = 11pi/6 = 5.759586532 radians
5.759586532 to degrees ==> a = 330 degrees
Answer:
330 degrees
to solve this system I first multiplied the second equation by 2 to make the x coefficient equal. then I subtracted equation two from equation one. this eleminated the x. solving for y gave me y=0. then I put 0 back in the original equation and that gave me x=-4.
