C. 33.60
that would be because 25% of 56 is 14 so 56-14=42
and 20% of 42 is 8.40
so 42-8.4= 33.60
$33.60 is your answer
Answer:
y = 3/4x - 2
Step-by-step explanation:
slope intercept form: y = mx + b
y-intercept(when x= 0) is given by b
slope is given by m
lets find the slope using the two given points, (4,1) and (8,4)
m = y2-y1 / x2-x1
m = 4 - 1 / 8 - 4
m = 3/4
Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).
1 = 3/4(4) - b
1 = 3 - b
b = -2
now you have m and b so you can finish writing your equation.
y = mx + b
y = 3/4x - 2
Answer: 5
Step-by-step explanation:
AE is half of AC
2 (x + 2) = 5x - 11
2x + 4 = 5x - 11
+ 11 + 11
2x + 15 = 5x
- 2x - 2x
15 = 3x
/ 3 / 3
x = 5
Answer:
x = 72
Step-by-step explanation:
36 - x = -36
*subtract 36 from both sides*
-x = -72
*divide by -1*
x = 72
Answer:
Given:
n = 15
c = 95% = 0.95
