Answer:
<h2>350 children</h2>
Step-by-step explanation:
x = Number of adults
x + x + 68 = 632
2x = 632 - 68
2x = 564
x = 282
282 + 68 = 350
350 children.
We can always check.
282 + 350 =
It equals 632, so we know our answer is correct.
Tan socks = 4
Grey socks = 7
Total number of socks = 4+7 = 11 socks
Probability of picking a tan sock then grey sock:
P(T)*P(G) = (4/11)*(7/10) = 14/54
Probability of picking a Grey sock then Tan sock
P(G)*P(T) = (7/11)*(4/10) = 14/55
Probability of two different colored socks
P(T&G)+P(G&T) = (14/55)+(14/55) = 28/55
6x² + 2x - 20 = 0
3(2x² + x - 10) = 0
3[(2x² - 4x + 5x - 10)] = 0
3[2x(x - 2) + 5(x - 2)] = 0
3(2x + 5)(x - 2) = 0
3=0, 2x + 5 = 0, x - 2 = 0 (Note: 3=0 is false so disregard that equation)
x =
, x = 2
Answer: x = {
, 2}
Answer:
132
Step-by-step explanation:
Answer: x = 7, x = -15
Step-by-step explanation:
This is an absolute value equation, so it has to be simplified first
|x+4|+10=21
|x+4|=11
Then you set it equal to the two values it can be, getting rid of the absolute value sign.
x+4=11
x+4=-11
x = 7
x = -15
Voila!
