Answer:
$108
Step-by-step explanation:
From the above question, we have the proportion:
Company A/Company B
= $9/$2 = x/x24
The next step is : We Cross Multiply
2x = $24 × $9
x = $24 × $9/2
x = $108
Therefore, she will invest in $108 company A if she invests $24 in company B.
Answer:
k = 77/10
Step-by-step explanation:
The jar consist of blue, red and green marbles . The probability of each of them can be described as follows.
probability of blue marbles = 2/7
probability of red marbles = 3/k
probability of green marbles = 5/2k
The sum of the individual probability is equals to 1. Therefore,
2/7 + 3/k + 5/2k = 1
collect like terms
(6 + 5)/2k = 1 - 2/7
11/2k =(7 - 2) /7
11/2k = 5/7
cross multiply
10k = 77
divide both sides by 10
k = 77/10
