help me please !!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

I believe it would be 3n^2 (last option)

Step-by-step explanation:

By definition;

monomial- one term

coefficient- the number in front of a variable

(in this case, without the squared power, it would look something along the lines of "3n", where the 3 is the coefficient and the "n" is the variable.)

sooooooo,

even without the "2nd degree" we can just use the system of elimination and cross out the answers that don't consist of one number, and that don't have a coefficient of 3.

I hope this answer was helpful, please let me know if you got it correct. :)

1. Solve for x. 5% + 15 = 28 (5 points)

Answers

Answer:x=2.6

Step-by-step explanation:

Simplifying (5x + 15) = 28 Reorder the terms: (15 + 5x) = 28 Remove parenthesis around (15 + 5x) 15 + 5x = 28 Solving 15 + 5x = 28 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + 5x = 28 + -15 Combine like terms: 15 + -15 = 0    0 + 5x = 28 + -15 5x = 28 + -15 Combine like terms: 28 + -15 = 13 5x = 13 Divide each side by '5'. x = 2.6 Simplifying x = 2.6

1. 8x + 16 = 6x - 12
x=

Answers

Answer:

x = − 14

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Hope this helps :)

Answer:

x= -14

Step-by-step explanation:

Isolate x to one side of the equation so subtract the 6x from 8x to get 2x

New equation

2x+16= -12

Now subtract 16 from both sides, so 16 minus 16 cancels out and then -12 - 16 equals -28

Newest equation

2x= -28

divide by 2 to isolate the x

So the answer is -14

x= -14

Fast food hamburgers have high amounts of cholesterol. Two McDonald’s Quarter Pounders and three Burger King Whoppers contain a total of 395 mg of cholesterol. Three Quarter Pounders and one Whopper contain a total of 288 mg of cholesterol. Determine the cholesterol content in each hamburger.

Answers

Answer:

McDonald’s Quarter Pounders = 67 mg of cholesterol

Burger King Whoppers = 87 of cholesterol

Step-by-step explanation:

McDonald’s Quarter Pounders = m

Burger King Whoppers = b

2m + 3b = 395

3m + 1b = 288

3m + b = 288

b = -3m + 288

2m + 3b = 395

2m + 3(-3m + 288) = 395

2m - 9m + 864 = 395

- 7m + 864 = 395

- 7m/7 = -469/7

-m = -67

-m/-1 = -67/-1

m = 67

2m + 3b = 395

2(67) + 3b = 395

134 + 3b = 395

3b = 395 - 134

3b = 261

3b/3 = 261/3

b = 87

Check: m = 67; b = 87

2m + 3b = 395

3m + 1b = 288

2m + 3b = 395

2(67) + 3(87) = 395

134 + 261 = 395

395 = 395

3m + 1b = 288

3(67) + 1(87) = 288

201 + 87 = 288

288 = 288
