Answer:
250
Step-by-step explanation:
To find the mean of the data set you would add all the number of the data set (2,2,2,3,4,4,4,4,6,6,7,7,7,8 )-data set based on dot plot then add all number together which would give you 75 then you would divide by the amount of numbers (15) and 75/15=5 so your mean would be 5
<h3><u>The value of a is equal to 0.93.</u></h3>
-6(7a - 4) = 3(a - 7) + 3
Distributive property.
-42a + 24 = 3a - 21 + 3
Add 42a to both sides.
24 = 45a - 21 + 3
Combine like terms.
24 = 45a - 18
Add 18 to both sides.
42 = 45a
a = 0.93
Given:
Bus fare = 1.50
coupon book = 24
bus fare w/ coupon book = 0.50
let x be the number of bus rides.
1.50x = 0.50x + 24
1.50x - 0.50x = 24
1x = 24
x = 24
24 bus rides for both to have the same cost.
1.50x = 0.50x + 24
1.50(24) = 0.50(24) + 24
36 = 12 + 24
36 = 36
The answer would be (4,2) I’m pretty sure I may be wrong tho
