3 * 5 = 15 miles during weekdays
6.5*2 = 13 miles on weekends
13 +15 = 28 miles total
28 / 7 = 4 miles average per day
n(A-B) denotes elements which are in A but not in B
n(Au B) denotes elements in A and B
n(AnB) denotes elements that are common in A and B
Now I will add one more set
n(B-A) which denotes elements in B but not in A
So, n(AuB) = n(A-B) + n( B-A) +n(AnB)
70 = 18 +n(B-A) + 25
70 = 43 + n(B-A)
n(B-A) = 70-43
n(B-A) = 27
So, n(B) = n( B-A) + n( AnB)
= 27+25
= 52
6. the answer is 6. because 3x what she has is equal to 18 all u do is divide. u get six.
Answer:
2/9
Step-by-step explanation:
Find the slope of the line with x intercept 9 and y intercept of -2
Given that the equation of the line is y = mx+b
x intercept occurs when y = 0
The coordinate of x intercept is (9,0)
y intercept occurs at x = 0
The coordinate of y intercept is (0, -2)
Slope m = y2-y1/x2-x1
m = -2-0/0-9
m = -2/-9
m = 2/9
Hence the required slope is 2/9
The answer is 1because a number is multiple by 20 then 200 and multiple by 3 -7=1
