Answer:
2/13 or 15.38%
Step-by-step explanation:
Number of Aces in a deck = 4
Number of 7s in a deck = 4
Number of cards in a deck = 52
Probability of A or 7 = (4 Aces + 4 Sevens) / 52 cards 8 cards / 52 cards
This simplifies to 2/13 or 15.38%
Children = .65 * people
people = 520 / .65
800 people were in attendance
Answer:
he didnt subtract each equations on both sides
5y-6=4y+1
-4 -4
y -6=1
+6=+6
y=7
Step-by-step explanation:
hope that wrk
Answer:
Step-by-step explanation:
(x - 2)/2 = 4
x - 2 = 8
x = 10
(y + 2)/2 = -3
y + 2 = -6
y = -8
(10, -8)
I'm going to assume you need this inequality solved.
First, write it as numbers, not words.
7/10n + 14 < 49
where "n" is the unknown number.
Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.
7/10 = 0.7
Now, solve it like you would any other equation.
0.7n + 14 < 49
0.7n +14 - 14 < 49 - 14
0.7n < 35
0.7n ÷ 0.7 < 35 ÷ 0.7
n < 50
The answer is n < 50
