Answer:
x = 2
y = 4
Step-by-step explanation:
y = 2x
x = -y + 6, y = 6 - x
substitute for y:
2x = 6 - x
3x = 6
x = 2
y = 4

120/1500=x/100, x=8
So, you make 8% commision, meaning you now have to do this:
x/1300=8/100, so x=$104

9. A bag of M&M's contains 4 red, 1 blue, 3 yellow, and 2 brown. What is the probability
of Maggie choosing a yellow M&M, eating it, and then choosing another yellow M&M?
Answer:
1/15
Step-by-step explanation:
Given that:
Total Number of M&M's = (4 + 1 + 3 + 2) = 10
Number of yellow M&M's = 3
Probability = required outcome / Total possible outcomes
First pick (choosing without replacement)
P(choosing a yellow M&M) = 3 / 10
Second pick :
P(choosing a yellow M&M) = 2 / 9
P(choosing 2 yellow M&M) = 3/10 * 2/9 = 6/90 = 1/15
What is:
1/4 (q-12) + 1/4 (q-4)
simplified??
Answer: -b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)
Hope this helps.

How many 12 Feet 2 x 4 would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
Your question has confusing details. So, I will rephrase as:
How many 2' x 4' would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
Answer:
12.5 plates
Step-by-step explanation:
Given
Building dimension:
[tex]Length = 25ft[/tex]
[tex]Width = 50ft[/tex]
Plates
[tex]Length = 2ft[/tex]
[tex]Width= 4ft[/tex]
To do this, we have to divide the dimension of the building by the dimension of the plates
So, we have:
[tex]n = \frac{Length\ of\ Building}{Length\ of\ Plates}[/tex]
and
[tex]n = \frac{Width\ of\ Building}{Width\ of\ Plates}[/tex]
For the length, we have:
[tex]n = \frac{25}{2}[/tex]
[tex]n = 12.5[/tex]
For the width, we have:
[tex]n = \frac{50}{4}[/tex]
[tex]n = 12.5[/tex]
So, 12.5 of the plates are needed
Every year, a car loses 15% of the value it had the year before. If the car's initial value is $ 24,000, then how long will it take for the car to be worth half of its value?
Answer:
4.62 years
Step-by-step explanation:
Half the car's value =>$24,000/2 = $12,000
The formula for exponential decrease =
y = a(1 - r)^t
y = Initial value = $24,000
a = Value after time t = $12,000
r = Decrease rate = 15% = 0.15
t = time in years =??
Hence,
24,000 = 12000 ( 1 - 0.15)^t
Divide both sides by 12000
24000/12000 = 12000 ( 0.85)^t/ 12000
2 = 0.85^t
We take the logarithm of both sides
log 2 = log (0.85)^t
log 2 = t log 0.85
Divide both sides by log 0.85
t = log 2/log 0.85
t = 4.62098120373 years
Approximately = 4.62 years
It would take 4.62 years to be worth half the initial price

Step-by-step explanation:
Sara puts $4,000 into an investment yielding 5% annual simple interest; she left the money in for five years and 6 months. How much interest does Sara get at the end of those five years and 6 months?
Answer: [tex]\$1100[/tex]
Step-by-step explanation:
Given
Principal amount is [tex]P=\$4000[/tex]
Rate of interest [tex]R=5\%[/tex]
Time period [tex]T=5\ yr\ \text{and}\ \text{6 months}\equiv 5.5\ yr[/tex]
We know, Simple interest is
[tex]\Rightarrow S.I.=\dfrac{P\times R\times T}{100}[/tex]
Putting values
[tex]\Rightarrow S.I.=\dfrac{4000\times 5\times 5.5}{100}=\$1100[/tex]
Sara gets [tex]\$1100[/tex] after 5 years and 6 months

EXERCÍCIOS 01) Resolva. A Lino tinha R$430,00 para pagar as seguintes contas R$ 119,00 de energia elétrica, R$65,00 de água e RS97,00 de telefone para fazer algumas compras. Quanto the restou para fazer as compras
Answer:
$149
Step-by-step explanation:
The computation of the amount left for the shopping is shown below;
= Amount have - Electricity bill - Water bill - telephone bill
= $430 - $119 - $65 - $97
= $149
We simply deduct all expenses from the amount available so the remaining amount i.e. left would be considered for shopping
