A summer camp cookout is planned for the campers and their families. There is room for 200 people. Each adult costs $4, and each camper costs $3. There is a maximum budget of $750. Write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers. x + y ≤ 200 4x + 3y ≤ 750 x + y ≤ 750 4x + 3y ≤ 200 x + y ≤ 200 3x + 4y ≤ 750 x + y ≤ 750 3x + 4y ≤ 200
Answer:
I think its A
Step-by-step explanation:
The required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.
What is inequality?Inequality is a non-equal relation between two expressions involving variables and constants.
The sign of the inequality can be, less than (<), greater than (>), less than or equal to (≤), or greater than or equal to (≥).
How to solve the question?In the question, we are asked to write the system of inequalities to represent the given scenario, where x is the number of adults and y is the number of campers.
We are informed that there is a room for 200 people.
Thus, the total number of people, that is, the number of adults + the number of campers, or, x + y should be less than or equal to 200.
This gives us an inequality:
x + y ≤ 200.
We are informed that the cost of an adult is $4 and the cost for a camper is $3, and the total budget is $750.
Thus, the total cost, that is, the cost of all adults + the cost of all campers, or, 4x + 3y should be less than or equal to 750.
This gives us an inequality:
4x + 3y ≤ 750.
Thus, the required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.

What is 4 3/10 plus (-6.2) in decimal form
Answer:
Step-by-step explanation:
First change 4 3/10 to 4.3. Then you change 4.3 + -6.2 to 4.3 - 6.2.
Then you do 4.3 - 6.2 and you should get - 1.9.
Answer:
The answer is (-1.9)
Step-by-step explanation:
4 3/10 = 4 × 10 + 3/10 = 43/10 = 4.3
Now,
4.3 - 6.2 = -1.9
Thus, The answer is (-1.9)

19= X+5*Z-12
what is X and Z?
Answer:
X = -5Z + 31
Step-by-step explanation:
Subtract 5Z5Z from both sides.
19 - 5Z = X - 12
19 − 5Z = X − 12
2 Add 1212 to both sides.
19 - 5Z + 12= X
19 − 5Z + 12= X
3 Simplify 19-5Z+1219−5Z+12 to -5Z+31−5Z+31.
-5Z + 31 = X
−5Z + 31 = X
4 Switch sides.
X = -5Z + 31
X = −5Z + 31
Answer:
19=x+5*z-12
19+12=x+5*z
31=x+5*z
then x=26 z=1

Step-by-step explanation:
The mass of 1 L of water is 1 kg. The mass of gasoline is 0.68 times the mass of water. What is the mass of the gasoline in a full tank that holds 75 L.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.
What is the mass?
Mass refers to the quantity of matter in an object. Mass is generally measured by how much something weighs. The more matter something has, the more it will weigh.
Here given that,
The mass of [tex]1[/tex] L of water is [tex]1[/tex] kg. The mass of gasoline is [tex]0.68[/tex] times the mass of water.
As we know,
[tex]1L=1000ml[/tex]
So, [tex]0.68[/tex]×[tex]1000=680grams[/tex]
As per this the mass of water is greater than the mass of gasoline.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.

Answer:
Melinda saves 2 less dollars than Marcus each week.
Step-by-step explanation:
Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.
14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.
Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.
