11/26 chance that the student plays both instruments.
First, add the amount of students that just play flute or piano:
3 + 5 = 8
Then add 8 to the amount that does not play either instrument:
8 + 7 = 15
Then do:
26 - 15 = 11
Then place 11 over the amount of people:
11/26

Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find the value of f(-3)
we have

we know that
f(-3) is the value of the function f(x) for x=-3
so
substitute the value of x=-3 in the function to find f(-3)



Part 2) Find the value of g(3)
we have

we know that
g(3) is the value of the function g(x) for x=3
so
substitute the value of x=3 in the function to find g(3)


<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>1</u><u> </u><u>:</u>
replace x and y by their value 1 and 3
3 = 4(1) - 1 = 4-1 = 3
2(1) + 3 = 2 + 3 = 5
correct
<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>2</u><u> </u><u>:</u>
y = 4x - 1
2x + y = 5
y = 4x - 1
y = -2x + 5
y - y = 4x - 1 - ( -2x + 5 )
0 = 4x - 1 + 2x - 5
6x - 6 = 0
6x = 6
x = 6/6 = 1
y = 4x - 1
y = 4(1) - 1
y = 3
correct
Answer:

Step-by-step explanation:
use the comparison method
no. of copies. $
10 4
x. 34
4x = 34×10
x= 340/4
x= 85
the value of x is 85
