-40 +2n= 4n -8(n+8)

-40 +2n= 4n -8n -64
-40 + 2n = -4n -64
2n = -4n -64 +40
2n=-4n-24
2n+4n=-24
8n=-24
N= -3

Answer is n equals -3

Answer: n = 6

Step-by-step explanation:

The given equation is expressed as

-40+2n = 4n-8(n+8)

We would open the parenthesis on the right hand side of the equation by multiplying each term inside the parenthesis by the term outside. It becomes

- 40 + 2n = - 4n - 64

We would make all terms containing n to be on the left hand side of the equation and the constant terms to be on the right side of the equation. It becomes

2n - 6n = - 64 + 40

- 4n = - 24

Dividing the left hand side and the right hand side of the equation by

- 4, it becomes

- 4n/-4 = - 24/-4

n = 6

When will the equation p(b)=520(0.88)^b have a value less than 100?
yulyashka [42]

Answer:

The given equation will have value less than 100 whenever the value of b is greater than 12.89

Step-by-step explanation:

For the given equation, p(b) = 520 × 0.88^{b} to have a value less than 100 we can establish inequality as:

                     p(b) < 100

         or,  520 × 0.88^{b} < 100

         or, \frac{520}{520} × 0.88^{b} < \frac{100}{520}

         or, 0.88^{b} < \frac{1}{5.2}

         or, ㏒ ( 0.88^{b} ) < ㏒  (\frac{1}{5.2})

         or, b× ㏒ 0.88 < ㏒  (\frac{1}{5.2})

         or,  \frac{log (\frac{1}{5.2}) }{log (0.88)}   <  b

         or, 12.89 < b

Hence for the equation to have value less than 100, b must be greater than 12.89.

Eduardo spent $34 on a magazine and some candy bars if the magazine cost $6 and each candy bar cost $4 then how many candy bars
tatiyna

Answer: 7 candy bars

Step-by-step explanation:

First we need to subtract the cost of the magazine from the total cost

$34-$6=$28

Now the $28 that remains is the cost of all the candy bars, so if we divide by the price, we will get  the amount.

$28/$4=7 candy bars
