Answer:
The system of equations is the option A
Step-by-step explanation:
Let
x ------> the number of tickets for the roller-coaster
y ------> the number of tickets for the bumper
z ------> the number of tickets for the Ferris wheel
we know that
The system of equations is equal to
<em>John</em>
2x+3y+z=42
<em>Darren</em>
3x+y+2z=36
<em>Shelley</em>
x+2y+3z=32
therefore
The system of equations is the option A
Answer: C (18)
Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.
Hello! :)
What is the probability of choosing a pen from the first box? It is 5/10 = 1/2.
What is the probability of selecting a crayon from the second box? It is 5/8.
The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/2 = 5/16.
Hope this helped and I hope I answered in time!
Good luck!

Answer:
Step-by-step explanation:
A rectangular gate has a diagonal bar running across it.The gate is 80cm high and 2m wide.Work out the length of the bar.Give your answer in surd form..
1. vertex is -4 because:
x^2-8x-20,
a=1, b=-8 , c=-20
use vertex form! -b/2a = -8/2(1) = -8/2 = -4.
2. axis of symmatry is the x which is also -4. The same steps go for the second one.
3. y intercept, I think the answer is -20. Im not sure for this one.
