Answer:
The number of adults, a, is 300, and the number of kids, k, is 200
k + a = 500 (1)
3k + 10a = 3,600 (2)
Then Multiply both sides of equation (1) by -3
(k + a) • -3 = 500 • -3
-3k − 3a = -1,500
Now, add this equation to equation (2)!
3k + 10a = 3,600
+ -3k − 3a = -1,500
7a = 2,100
a = 300
And last Substitute the value of a into equation (1).
k + a = 500
k + 300 = 500
k = 500 – 300
k = 200

Answer:
24
Step-by-step explanation:
The LCM of 8 and 12 is 24. Find least common multiple (LCM) of: 16 & 24 4 & 6 24 & 36 40 & 60 56 & 84 16 & 12 8 & 24 24 & 12 8 & 36 40 & 12 8 & 60 56 & 12 8 & 84
Answer:
$43 million
Step-by-step explanation:
<h3>Step 1. Turn the sentence into an equation (total = T)</h3>
15.4 million = 0.36 (T)
<h3>Step 2. Solve for T </h3>
15,400,000 / 0.36 = T
42,777,777.78 = T
$42.8 million ≈ $43 million (rounded)
The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!
Hope this helps :)
Answer:
a(7) = -0.4
Step-by-step explanation:
The general formula for a geometric progression is a(n) = a(1)*r^(n - 1), where r is the common ratio. In this problem, a(1) = -6250. To find r, we divide 1250 (the 2nd term) by -6250 (the 1st term), obtaining r = -0.2.
Then the formula for THIS geometric progression is
a(n) = -6250*(-0.2)^(n - 1).
Thus, the 7th term of THIS progression is
a(7) = -6250*(-0.2)^(7 - 1), or -6250*(-0.2)^6, or -0.4
