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.
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. 8x + 16 = 6x - 12
x=
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
Hope this helps you!!!

2.(5,3) & (5,-9) 3.(2,1) & (8,9)
4.(14,-8) & (7,-6). 5.(4,-3) & (8,3)
Step-by-step explanation:
1.(4,9) & (1,6)
m=y²-y¹/x²-x¹
m=6-9/1-4
m=-3/-3
m= 1
2.(5,3) & (5,-9)
m=y²-y¹/x²-x¹
m=(-9)-3/5-5
m=-12/0
3.(2,1) & (8,9)
m=y²-y¹/x²-x¹
m=9-1/8-2
m=8/6
m= 4/3
4.(14,-8) & (7,-6)
m=y²-y¹/x²-x¹
m=(-6)-(-8)/7-14
m=2/-7
m= -2/7
5.(4,-3) & (8,-3)
m=y²-y¹/x²-x¹
m=(-3)-(-3)/8-4
m=0/4
m=0

Another geometry problem
Answer:
70 degrees
Step-by-step explanation:
2x+15=4x-5
subtract 2x from both sides
15=2x-5
add 5 to both sides
2x=20
divide both sides by 2 to get x by itself
x=10
You now have to add the equations together and plug in the x
(2(10)+15) + (4(10)-5)
(20+15) + (40-5)
35+35= 70
70 degrees

5. What three consecutive integers have a sum of 21?
help me please !!!!!!!!!!!!!!!!!!!!!!!!!
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. :)

Maria and Franco are mixing sports drinks for a track meet. Maria uses 23 cup of powdered mix for every 2 gallons of water. Franco uses 114 cups of powdered mix for every 5 gallons of water.
Answer:
Maria
Step-by-step explanation:
Find the ratio of powdered mix to water for each drink.
For Maria:
(2/3 cup) / (2 gallon)
= 1/3 cup per gallon
For Franco:
(1 1/4 cup) / (5 gallon)
= (5/4 cup) / (5 gallon)
= 1/4 cup per gallon
Since 1/3 is bigger than 1/4, Maria's sports drink is stronger.

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

This is a special cube, which has numbers from 1 to 6 marked on its six faces. (Each number is marked on exactly one face.) Also, the sum of each pair of opposite faces is the same
Answer:
This is a die used to play games. Well we generally use more than one, so we use dice. The addition of each pair of opposite sides always yields 7:
1 + 6 = 72 + 5 = 73 + 4 = 7Dice games are very popular and they can also help understand how math and probability work. As with all games, probability always favors the house, but the risk of loss is part of the entertainment.

Determine the pattern rule for the table and write it as an equation.
Answer:
The rule is: y = -10x+85
Step-by-step explanation:
The rule is given by:
[tex]y = mx+b[/tex]
Here m is the gradient and b is the y-intercept.
We have to take two pairs of input-output to find the rule
Let the two pairs be:
(x1,y1) = (1,75)
(x2,y2) = (2,65)
Slope is found using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Putting the values
[tex]m = \frac{65-75}{2-1}\\m = -10[/tex]
Putting the value of slope
[tex]y = -10x+b[/tex]
Putting a pair of input-output in the equation (1,75)
[tex]75 = -10(1) +b\\75 = -10+b\\b = 75+10\\b = 85[/tex]
Putting the value of b
[tex]y = -10x+85[/tex]
Hence,
The rule is: y = -10x+85
