Solve for n:
6n − 2(4n + 7) + 4 = -2
A:-6
B:-4
C:4
D:6

Answers

Answer 1

Answer:

B: -4

Step-by-step explanation:

In this type of situation, you should distribute -2 into the parentheses to get to this equation which is 6n - 8n - 14 + 4 = -2.  Combine the two variable numbers together to get -2n and add 4 from -14 to get -10.  To clean up this equation, your equation should be -2n - 10 = -2.  Add 10 on both sides to get 8 on the right side and then divide -2 on both sides to get your final answer which is -4.

Answer 2
O believe it’s B:-4

Answer:

the answer is the second one, 55x-17

Step-by-step explanation:

a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?

Answers

There are 12 Nickels, 9 Quarters, and 15 Dimes.

Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.

Creating a system of equations thus :

n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)

Substitute for n and q

(q+3) + (q+6) + q = 36

3q + 9 = 36

3q = 36 - 9

q = 27 ÷ 3

q = 9 quarters

n = 9 + 3 = 12 nickels

d = 9 + 6 = 15 dimes

Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.

write an equation in slope-intercept form when given the information:
slope = 0, goes through the point (-3 , 3)

Answers

Answer:

[tex]y=3[/tex]

Step-by-step explanation:

We are given the slope of the line and a point on the line.

So, we can utilize the point-slope form, given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

We know that the slope is 0. So, m = 0.

And we will let (-3, 3) be (x₁, y₁). Hence, by subsitution:

[tex]y-(3)=0(x-(-3))[/tex]

Simplify:

[tex]y-3=0[/tex]

We can add 3 to both sides. Hence, our equation is:

[tex]y=3[/tex]

As you would've expect, since it had a slope of 0, it is a horizontal line.

The answer to the question is y=3

Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.
