Answer:
8/5
Step-by-step explanation:
w = k / √x
4 = k / √4
k = 8
w = 8 / √x
w = 8 / √25
w = 8/5
3000 tickets, 3 prizes
1/3000 * 35,000 = $11.67 gain
1/3000 * 900 = $0.30 gain
1/3000 * 600 = $0.20 gain
Cost $18
$11.67 + 0.30 + 0.2 - 18 = - 5.83
Loss of $5.83 per ticket
If one is positive we can conclude that the other is also positive
Positive*positive=positive(24)
The product of the two numbers is 24
And the smaller number is less than the greater number by 2
Factors of 24=1*24,2*12,3*8,4*6.
The only pair with the diffrence of two is 4*6
Therefore the two integers are 4 and 6
(3-i)2=3*2-2i=6-2i
HAVE A NICE DAY!! ^^
Combine like terms that share a common variable. If a scalar multiple is outside the parentheses, use the distributive property to expand the expression.
15) I cannot read the whole expression.
16) 4n - n = 3n
17) -3x - 9 + 15x = 12x - 9
18) -9k + 8k = -k
19) -16n - 14n = -30n
20) 15n - 19n = -4n
21) - 4 + 7(1 - 3m) = -4 + 7 - 21m = -21m + 3
22) -5n + 3(6 + 7n) = -5n + 18 + 21n = 16n + 18
23) -2n - (9 - 10n) = -2n - 9 +10n = 8n - 9
24) 10 - 5(9n - 9) = 10 - 45n + 45 = -45n + 55
25) 9a + 10(6a - 1) = 9a + 60a - 10 = 69a - 10
26) -9(6m - 3) + 6(1 + 4m) = -54m + 27 + 6 + 24m = -30m + 33
27) -10(1 - 9x) + 6(x - 10) = -10 + 90x + 6x - 60 = 96x - 70
28) 5(-2n + 4) + 2(n + 3) = -10n + 20 + 2n + 6 = -8n + 26
