what is X and Z?
Answers
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

The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?
₋₋₋₋₋₋₋₋ °F per hour
Answers
Answer:
-3.5
Step-by-step explanation:
As there was a total change of -21, that would be the first part of your equation:
-21
As 6 hours had passed and you are trying to find the mean, your equation would now be:
-21 ÷ 6 = ?
Now you can solve the equation, and the answer is -3.5°F per hour.
The mean change in temperature per hour is -3.5 °F.
what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total change in the outdoor temperature over 6 hours was -21°F
So, in one hour the mean change in temperature
= -21/6
= -3.5 °F
Hence, the mean change in temperature per hour is -3.5 °F.

What is 4 over 9(as a fraction) to the power of 2?
Answers
Answer:
16/81
Step-by-step explanation:
To square a fraction, you would have to square both the denominator and the numerator. You would have to do 4x4/9x9, which is 16/81.
Answer:
The answer is 16/81
Step-by-step explanation:
To evaluate this equation first find a understanding of what needs to be solved.
Here we see that we need to solve 4/9th to the power of 2.
to solve this we find what 4 to the power of 2 is and what 9 to the power of 2 is.
To use the power of 2 you multiply the number to itself that many times so if its 5 to the power of 3 you would right it as 5 x 5 x 5.
In this case we need to do 4 x 4 and 9 x 9.
4 x 4 = 16
9 x 9 = 81
The 4 x 4 solution remains as the numerator
The 9 x 9 solution remains as the denominator
After solving we get 16/81, due to the 81 not being even and 16 not being a multiple we can not simplify this fraction anymore.
The correct answer is 16/81 have a great day :)

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
Answers
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.

Answers
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.
