3 is on quadrant 1 on the x axis. And 1 is on quadrant 1 on the y axis
3/4 bc 1 1/4 divided by 20 is 1/16. 1/16 times 12 is 3/4
Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+x+3=18
(4x+x)+(3)=18(Combine Like Terms)
5x+3=18
5x+3=18
Step 2: Subtract 3 from both sides.
5x+3−3=18−3
5x=15
Step 3: Divide both sides by 5.
5x/5 = 15/5
x=3
Answer:
C. 2,150
Step-by-step explanation:
We know that out of 120 passengers, 86 were satisfied with the service.
To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%).
Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150.
