7n+2 = 4n+17 solve the equation

Answers

Answer 1

Answer:

n = -5

Step-by-step explanation:

Solve for n:

n + 2 = 4 n + 17

Hint: | Move terms with n to the left hand side.

Subtract 4 n from both sides:

(n - 4 n) + 2 = (4 n - 4 n) + 17

Hint: | Combine like terms in n - 4 n.

n - 4 n = -3 n:

-3 n + 2 = (4 n - 4 n) + 17

Hint: | Look for the difference of two identical terms.

4 n - 4 n = 0:

2 - 3 n = 17

Hint: | Isolate terms with n to the left hand side.

Subtract 2 from both sides:

(2 - 2) - 3 n = 17 - 2

Hint: | Look for the difference of two identical terms.

2 - 2 = 0:

-3 n = 17 - 2

Hint: | Evaluate 17 - 2.

17 - 2 = 15:

-3 n = 15

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 15 by -3:

(-3 n)/(-3) = 15/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 15/(-3)

Hint: | Reduce 15/(-3) to lowest terms. Start by finding the GCD of 15 and -3.

The gcd of 15 and -3 is 3, so 15/(-3) = (3×5)/(3 (-1)) = 3/3×5/(-1) = 5/(-1):

n = 5/(-1)

Hint: | Simplify the sign of 5/(-1).

Multiply numerator and denominator of 5/(-1) by -1:

Answer: n = -5

Answer 2

Answer:

n = 5

Step-by-step explanation:

[tex]7n + 2 = 4n + 17[/tex]

➡️ [tex]7n - 4n = 17 - 2[/tex]

➡️ [tex]3n = 15[/tex]

➡️ [tex]n = 5[/tex] ✅

Step-by-step explanation:

Pete has 3 dollars less than what Linda has. If together has 81 dollars how much does each person have?

Answers

Answer:

Pete: 39, Linda: 42

Step-by-step explanation:

Suppose Pete has x dollars. If he has 3 dollars less than Linda, then Linda has 3+x dollars. Together, they have 81 dollars:

x+3+x=81

2x+3=81

2x=78

x=39

Since Pete has x dollars, and x=39, he has $39.

Linda has 3+x, which is 39+3 = $42

Explanation:

For the question on the left:

The number line counts by 0.3 every time. For each value in front of -0.5, just add 0.3 and that will be the next value.

For the question on the right:

-1/3 > -5.4 , because negative numbers closer to zero are bigger.

i need to reduce the radical 252

Answers

6x the square root of 7

Answer:

√252 = 6√7

Step-by-step explanation:

Double Prime Factor Method

The Double Prime Factor Method uses the prime factors of 252 to simplify the square root of 252 to its simplest form possible. This is how to calculate A and B using this method:

A = Multiply all the double prime factors (pairs) of 252 and then take the square root of that product. The prime factors that multiply together to make 252 are 2 x 2 x 3 x 3 x 7. When we strip out the pairs only, we get 2 x 2 x 3 x 3 = 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Divide 252 by the number (A) squared. 6 squared is 36 and 252 divided by 36 is 7. Therefore, B equals 7.

Once again we have A and B and can get our answer to 252 in its simplest radical form as follows:

√252 = A√B

√252 = 6√7

how many solutions does the system of equations have?(1 point)
3x=-12y+15 and x+4y=5
A-one
B-two
C-infinitely many
D-none

Answers

Answer:

c

Step-by-step explanation:

First, I'll isolate the x in x+4y=5 to match with the other equation.

The new equation would be x= -4y+5

Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.

-1(-12y + 15 = 3x )

3(-4y + 5 = x)

The new equations would be :

12y - 15 = -3x

-12y + 15 = 3x

Add the equations and you get

0 = 0

The equation has an infinite amount of solutions
