a) 24% said they wanted to learn french.
To find total number of students surveyed divide the number of students that want to learn French by the percentage:
12 / 0.24 = 50
There were 50 students surveyed.
b) 36% wanted to learn Spanish, multiply 50 by 36%
50 * 0.36 = 18
18 students wanted to learn Spanish.
Answer:
x = 
y = 
Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y =
x = 5y - 4
x = 5 ( ) - 4
x =
X - 10 = 25
add 10 to both sides
X = 35
Each must sell 35,678 dollars each year not counting commision to add 6 percent of that.
3x^3 x 4x^2 = 12x^5
3x^3 x 1 = 3x^3
2x^2 x 4x^2 = 8x^4
2x^2 x 1 = 2x^2
1x x 4x^2 = 4x^3
1x x 1 = 1x
12x^5 + 3x^3 + 8x^4 + 2x^2 + 4x^3 + 1x
Simplify
12x^5 + 7x^3 + 8x^4 + 2x^2 + 1x
Thus, answer is B
Hope this helps!
