I would say that the answer is true
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:
17.) 12
18.) 1/15
Step-by-step explanation:
2 ÷ 
This problem is asking how many 's can go into 2 blocks. If you divide one box into 6 parts, each tiny box will be of the whole. Divide the other box into 6 parts as well, and you will get 12 of these parts. Check your answer by multiplying 12 by . The answer is 
which is also equal to 2.
÷ 5
For this one, think of it as we have one big box divided into thirds. We want to divide each portion by 5. So you should have 5 tiny boxes in each which gives you a total of 15 boxes. But if we look at it as one big box divided into 15 parts, we know that each of those is 
. Check your answer by multiplying by 5 and you get 
which is equal to .
Let me know if you have any questions, and good luck!
Answer:
5x-6
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x - 9
f(x) + g(x) = 2x + 3 + 3x-9
= 5x-6
Answer:
-8+5√2 and -8-5√2
Step-by-step explanation:
Given the expression x² + 16x + 14 = 0
USing the general formulas
x = -16±√16²-4(14)/2
x = -16±√256-56/2
x = -16±√200/2
x = -16±10√2/2
x = -8±5√2
Hence the required solutions are -8+5√2 and -8-5√2
