-12=-6(-8n+6) + 8(-4+n)

Answers

Answer 1

Answer:

n = 1

Step-by-step explanation:

-12 = -6(-8n + 6) + 8(-4 + n)

multiply our right side:

-12 = 48n - 36 -32 + 8n

combine n terms on right side:

-12 = 56n - 36 -32

combine numbers on right side:

-12 = 56n - 68

add 68 to both sides:

-12 + 68 = 56n - 68 + 68

56 = 56n

divide both sides by 56:

56/56 = 56n/56

n = 1

check:

-12 = -6(-8(1) + 6) + 8(-4 + (1))

-12 = -6(-8 + 6) + 8(-3)

-12 = -6(-2) + 8(-3)

-12 = 12 - 24

-12 = -12

1. Jasmine is 5 years younger than twice her sister's age. If Jasmine is 39 years old, how old is her sister?

Answers

Let J be Jasmine age and S the sister's age. Then, we have

[tex]2S-5=J[/tex]

this equality means Jasmine is 5 years younger than twice her sister's age. Now, we also know that J=39 years then by substituying this value into the last equality, we have

[tex]2S-5=39[/tex]

and now, we can solve this equation for S. First, we must move -5 to the right hand side as 5. It reads

[tex]\begin{gathered} 2S=39+5 \\ 2S=44 \end{gathered}[/tex]

and finally, we obtain

[tex]\begin{gathered} S=\frac{44}{2} \\ S=22 \end{gathered}[/tex]

therefore, Jasmine's sister has 22 years old.

Dominique paid $15.50 to join an online music service. She purchases 10 songs each month at a cost of $0.99 per song. Dominique thinks that after 8 months, she will have spent around $75.00 total. Is Dominique's estimate reasonable?

Answers

If she thinks that after 8 months, she will have spent around $75.00 total.  Dominique's estimate is not reasonable?

Determining whether the estimated amount is reasonable

We have to make use of the given data to find whether amount of $75 which she estimated that she will spent after 8 months is reasonable

Total cost:

Total cost =$15.50  + 10 × $0.99 × 8

Total cost = $15.50 + 9.9 × 8

Total cost = $15.50 +$79.2

Total cost = $94.7

Hence,

$94.70 ≥ $75.00

Based on the above calculation the amount she estimated is not a reasonable amount because the total cost is greater that the estimated amount.

Therefore we can conclude that the estimate is unreasonable.

The estimate of the Dominique's is not reasonable.

Given that,
Dominique paid $15.50 to join an online music service. She purchases 10 songs each month at a cost of $0.99 per song. Dominique thinks that after 8 months, she will have spent around $75.00 total. Is Dominique's estimate reasonably is to be justified.

Here,
According to the question,
The total cost of the song for 8 months = 8 (0.99 x 10)
                                                            = $ 79.2
Total cost  = 15.50 + 79.2 = $94.7
Since the total cost exceeds Dominique's estimate so her estimate is not reasonable.

Thus, the estimate of the Dominique's is not reasonable.

A new minivan costs $24,897. About how much would 4 minivans cost?

Answers

Answer: about $100,000.

Step-by-step explanation: i gave an estimate because your answer calls for an estimate, not an exact answer. $100,000 is correct because 24,897*4 = 99,588.

99,588 because you would just multiply 24,897 times 4, then if u have to add tax you would multiply that by 99,588, tax is different in every state so you have to look up what ur tax rate is. Then once u have the tax add that to 99,588

The probability that your raffle ticket is not a winner is 0.9998. What is probability that your raffle ticket is a winner?

Answers

The probability of raffle ticket is a winner is 0.0002.

What is probability?

The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

Given:

probability that your raffle ticket is not a winner = 0.9998.

Now, we know if we have to find the complement probability we can use

P(E) = 1 - P(not E)

where E is any event.

Here, E = not winner

So, P( raffle ticket is a winner)

= 1- 0. 9998                                                  

= 0.0002

Hence, the probability of raffle ticket is a winner is 0.0002.

A supermarket sells 500g pots of yoghourt. There is a special offer on yoghourt:

A week later, the price of a single pot of yoghourt is still the same, but the offer changes to:
Buy 1 pot and get a second one half price!
Is the second offer better than the first? Show working to justify your answer.​

Answers

The first offer is better from the perspective of a customer but the second one is better from the perspective of a seller.

Here we have different 2 cases, and to find the answer we have to follow a few steps.

First of all, we should simplify these two cases and will try to give them a proper equation format.

Let's assume the price of each yogurt is $x.

Therefore the total price of 2 pots is (2× x) = $2x.

But the condition is if we buy 2 pots, get the 3rd one for free. So, we can purchase a total of 3 pots at the same cost.

∵ If 3 pots cost $2x, then the average cost for each pot is 2x/3 =$0.67x

( average value of each unit = Total value / total unit )

In the second case, if we buy 1 pot we can get the second one at half price.

Therefore, the total price of two pots is, ( x + 0.5x ) = $1.50x

∵ If 2 pots cost $1.50x, then the average cost for each pot is 1.50x/2 = $0.75x

( average value of each unit = Total value / total unit ).

The price of yogurt per pot in the first case <  The price of yogurt per pot in the second case.

As $0.67 <  $0.75.

x1 = 2

y1 = 11.9

Here,

x2 = 4

y2 = 13

Formula : -

Rise over run = ( y2 - y1 )/( x2 - x1 )

A farmer needs to enclose three sides of a garden with a fence (the fourth side is a river). The farmer has

garden be? (For the purpose of this problem, the width will be the smaller dimension (needing two sides);
the length with be the longer dimežision (needing one side). Additionally, the length should be as long as
possible.)

Answers

length×width = 108

length + 2×width = 30

length = 30 - 2×width

using that in the first equation

(30 - 2×width)×width = 108

-2×width² + 30×width - 108 = 0

the general solution to such a quadratic equation like

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

so,

width = (-30 ± sqrt(30² - 4×-2×-108))/(2×-2) =

= (-30 ± sqrt(900 - 864))/-4 =

= (-30 ± sqrt(36))/-4 = (-30 ± 6)/-4

width1 = (-30 + 6)/-4 = -24/-4 = 6 ft

width2 = (-30 - 6)/-4 = -36/-4 = 9 ft

for width = 6 ft

length = 30 - 2×width = 30 - 12 = 18 ft.

for width = 9 ft

length = 30 - 2×width = 30 - 18 = 12 ft

given the request that the length sound be as long as possible,

width = 6 ft

length = 18 ft

is our solution.

Answers

The ratio of the number of history majors to the number of mathematics majors is 3 to 2.

When two objects are related using numbers or amounts, the relationship is known as a ratio.

Let E be the number of English majors, H be the number of history majors, and M is the number of math majors.

Now,

There are twice as many English majors as history majors.

E = 2 × H

There are three times as many English majors as mathematics majors.

E = 3 × M

Now, let's assume E = 6.

Then,

6 = 2 × H

H = 3 and,

6 = 3 × M

M = 2

Therefore, the ratio of the number of history majors to the number of mathematics majors will be:
