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

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

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

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.
