[tex]3x + 2y + 2z = 19\\3x + y + z = 14\\[/tex]
If the equations above are true, which of the following is the value of y + z?
(A.) -5
(B.) -4
(C.) 0
(D.) 4
(E.) 5
Answer:
The answer is E
Explanation:
Before we find the value of 5, let's find x by using the elimination process for the two given equation.
2(3x + y + z = 14) → 6x + 2y + 2z = 28
3x + 2y + 2z = 19
-6x + 2y + 2z = 28
-3x = -9
x = 3
Now plug in 3 into both of the given equations, which will give you your new equation, then subtract them:
3(3) + 2y + 2z = 19 → 9 + 2y + 2z = 19
3(3) + y + z = 14 → - 9 + y + z = 14
Our answer is: y + z = 5
Our value is 5
Optional: If you want to make sure it's 5, plug-in any random numbers for y and z that equals 5. For example: 3 + 2, 1 + 4, 5 + 0, 6 + (-1), etc...
Once you choose the numbers you can plug them into the two new given equations. For me, I decided to let y = 1 and z = 4:
9 + 2(1) + 2(4) = 19 9 + (1) + (4) = 14
9 + 2 + 8 = 19 9 + 1 + 4 = 14
19 = 19 14 = 14

A reflective mirror surface
A waterproof compass
Extra clothes and towels
Working navigation lights
Answer:

Working navigation lights:
These lights are essential for maintaining visibility and complying with maritime regulations, especially during low-light conditions or at night.
While the other items you mentioned can be important for various reasons, they may not necessarily be required by law or specifically listed on a standard Pre-Departure Checklist.
However, it's always a good idea to have additional safety equipment and supplies on board, such as a reflective mirror surface for signaling, a waterproof compass for navigation, and extra clothes and towels for comfort and emergencies.
Hence the correct option is working navigation lights.

Word problem.
First statememt
n/2 - 4 = -6. ....... (1)
Second statement.
3n + 7 = x. ....... (2)
From (1)
n/2 - 4 = -6.
n/2 = -6 +4
n/2 = -2
n= -4
Put n into (2).
3n + 7 = x
3(-4) +7 = x
x= -12 +7 = -5
The answer is -5.
How many credits of Science is a student required to take in the Foundation Graduation Program?
Answer:
Students can earn a Distinguished Level of Achievement under the Foundation program by completing four credits in math (must include Algebra II) and four credits in science, and obtaining at least one endorsement.
Explanation:
In a certain Algebra 2 class of 21 students, 12 of them play basketball and 14 of them
play baseball. There are 5 students who play neither sport. What is the probability
that a student chosen randomly from the class plays basketball or baseball?
Answer:
Explanation:
We know there are 21 students in all, so that should be the denominator in this answer.
Then, to find the numerator, we need to find the number of students that play basketball and the number of students that play baseball, assuming that none of them play both sports. Just add those two numbers to get the numerator, and then put it on top of the 21.
You either typed this question incorrectly, or there is a mistake, because there are more kids that play basketball or baseball than there are students in the class.
