What is the answer to 5(n-7)=2(n+14) work

Mathematics

aivan3 [116]3 years ago

Answer:

The answer is n=21.

Step-by-step explanation:

To solve the equation for (n), start by using the distributive property on both sides of the equation. The distributive property is multiplying the sum of two or more addends by a number which will give the same result as multiplying each addend individually by the number and then adding the products together.

The equation will look like 5n-35=2n+28 after using the distributive property. Next, add 35 to both sides of the equation, which will look like 5n=2n+63, and then subtract (2n) from both sides of the equation, which will look like 3n=63. The next step is to simplify the equation, which will look like n=21, and the final answer to the equation will be n=21.

Answer:

n = 21

Step-by-step explanation:

5(n-7)=2(n+14)

Distribute

5n -35 = 2n+28

Subtract 2n from each side

5n-2n -35 = 2n-2n +28

3n-35 =28

Add 35 to each side

3n-35+35 = 28+35

3n = 63

Divide by 3

3n/3 = 63/3

n =21

The exponential equation of the model is A(t) = 2583 * 0.88^t and the multiplier means that the number of new cases in a week is 88% of the previous week

<h3>The function that models the data</h3>

The given parameters are:

New, A(t) = 2000

Rate, r = 12%

The function is represented as:

A(t) = A * (1 - r)^t

So, we have:

2000 = A * (1 - 12%)^t

This gives

2000 = A * (0.88)^t

2 weeks ago implies that;

t = 2

So, we have:

2000 = A * 0.88^2

Evaluate

2000 = A * 0.7744

Divide by 0.7744

A = 2583

Substitute A = 2583 in A(t) = A * 0.88^t

A(t) = 2583 * 0.88^t

Hence, the exponential equation of the model is A(t) = 2583 * 0.88^t

<h3>The interpretation of the multiplier</h3>

In this case, the multiplier is 88% or 0.88

This means that the number of new cases in a week is 88% of the previous week

Amiraneli [1.4K]

Answer:

23 friends

Step-by-step explanation:

Let the number of friends she has = x

Total number of gum = 47 pieces

She gave 2 each to her friends, hence:

2x + 1 = 47

2x = 47 - 1

2x = 46

x = 46/2

x = 23

Therefore, the number of friends she has is 23
