I need #7 done (show work) will give brainliest

Answer:

5(n+7)=40

Step-by-step explanation:

It's 5(n+7)=40 because 5 + 7n = 40 and 5n + 7 = 40 is addition not multiplication, and 5⋅7+n=40 is saying 5 times seven plus a number is 40, therefore 5(n+7)=40 is the correct answer because the parenthesis in (n+7) seperates it from 5 so that you have to get the sum of (n+7) before you can multiply it by 5.  

The required equation for the given case is 5(n + 7) = 40.

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The given word problem can be solved as follows,

Suppose the unknown number be n.

Then, 5 times the sum of the number and 7 can be written as an expression as,

5(n + 7)

Now, as per the question the following equation can be written,

5(n + 7) = 40

Hence, the equation for the given word problem is 5(n + 7) = 40.

The number is 3947

It should be noted that 36 hundreds will be equal to:

= 36 × 100

= 3600

It should be noted that 34 tens will be:

= 34 × 10

= 340

7 ones will be:

= 7 × 1

= 7.

Therefore, the sum will be:

= 3600 + 340 + 7 = 3947

Answer:

(3,5)

1/3

Step-by-step explanation:

The equation is already in point-slope form. Therefore, both the point and slope can easily be found in the equation. Point slope form looks like [tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]. In this the point is [tex](x_{1},y_{1})[/tex] and the slope is m. So, the x value is 3 and the y value is 5, making the coordinate (3,5). Finally, the slope is 1/3.

[tex]\\ \sf\longmapsto 9\dfrac{7}{11}-(5+1\dfrac{1}{2})[/tex]

Conservative. Replication produces one helix made entirely of old DNA and one helix made entirely of new DNA.

Semi-conservative. Replication produces two helices that contain one old and one new DNA strand.

Dispersive.

Answer:

Each pencil is $.50

Step-by-step explanation:

If the total amount she spends is 1.50 for 3 pencils, and each pencil costs the same. Then you have to divide the total amount by the variables. Leaving your equation to be:

1.50 ÷ 3

.50

Let cost of each pencil be x

Answer:

2 11/12

Step-by-step explanation:

This is what I got for the answer in the test.

The value of m in the given equation would be; m = 2.91

An equation is an expression that shows the relationship between two or more numbers and variables.

We need to find the value of m.

This equation could also be given by;

−2.4(m−5/6)=−5

Distribute the negative;

−2.4(m−5/6)=−5

- 2.4m + 2.4 x 5/6 = -5

Now we get;

- 2.4m = -5 - 2

- 2.4m = -7

m = 2.91

Hence, the value of m in the given equation would be; m = 2.91

Answer:

  see attached

Step-by-step explanation:

For each listed root x=p as signified by f(p) = 0, the function has a factor (x-p). The given roots and the given end behavior tell us the factored form is ...

  f(x) = -(x +3)(x +1)(x -1)(x -3)

__

The graph is attached. It shows the function increasing at extreme left, crossing the x-axis at x=-3, and again at x=-1, x=1 and x=3. Since it crosses an even number of times, the right-side end behavior is "decreasing" toward negative infinity.
