Answer:
26/52 50%
Step-by-step explanation:
52 cards in a deck, 26 are black and 26 are white.
Answer:
24 and 48
Today, the son is 24 years old, and the father is 48 years old.
Step-by-step explanation:
(x - 10) + (2x - 10) = 52
3x + 20 = 52
3x = 72
x = 24
The father is 2 times his son's age.
2x
= 2(24)
= 48
So, the son is 24 and the father is 48.
10 years ago, son was 14 and father was 38, if added, this adds up to 52, so we know our calculations are correct.

Colin spends 1/8 of an hour practicing each song
Answer:
The coefficient 6 in 6x means 6(x) or 6 multiplied by x 6 times.
Step-by-step explanation:
X could be anything, it is only holding the place of a number. The coefficient 6 before the x is a number being multiplied by the unknown variable, x. For example if x = 2 the expression would turn into 6(2) which equals 12.
