2x = 48, 3x = 72, 4x = 96, 6x = 144


2x + 3x + 4x + 6x = 360
15x = 360
x = 24

2x = 2(24) = 48
3x = 3(24) = 72
4x = 4(24) = 96
6x = 6(24) = 144

148=3x+3+4x+1 solve
Andreas93 [3]

Answer: 20.57142857

Step-by-step explanation:

148 = 3x + 3 + 4x + 1

Step one: combine like terms

148 = 7x + 4

Step 2: Subtract the 4 over to 148

144 = 7x

Step 3: Divide 7 on both sides

20.57142857 = x

Answer: 
Choice A
1/17; no, they are dependent events

============================================

Explanation:

There are 13 spades and 52 cards total. So 13/52 = 1/4 is the probability of drawing one spade

If we do not replace the card we pull out, then the probability of another spade is 12/51 since there are 12 spades left out of 51 total. 

Multiply the fractions 1/4 and 12/51 to get
(1/4)*(12/51) = (1*12)/(4*51) = 12/204 = 1/17

The two events are not independent because the second event (pulling out a second spade) depends entirely on what happens in the first event (pulling out a first spade). The fact that the probability is altered indicates we have dependent events.
