Answer:
Value of stamp collection = (45b + 43) cents
Step-by-step explanation:
What we have here is as follows;
if there are x 3-cent stamps, then there are 4x 10-cent stamps
So the number of 2-cent stamps is 1 less than 3 cent stamps and that will be x-1 2 cent stamps
Number of 2 cents stamps = b
This means that x-1 = b
Thus, x = b + 1
So the value of the stamp collection is as follows;
x 3 cents stamps = 3(b+ 1) = 3b + 3 cents
4x 10 cents stamps = 10(4(b + 1)) = 10(4b + 4) = 40b + 40
value of the 2 cents stamp = 2b cents
Total value is thus;
2b + 40b + 40 + 3b + 3 = (45b + 43) cents
Answer:
77.7 miles.
Step-by-step explanation:
We have been given that Louis has already biked 17.7 miles this week. He can bike 6 miles in one hour. Let the total biked be represented by d and let the number of hours biking be represented by h. an equation that represents this scenario is:
.
To find total number of miles Louis biked in 10 hours we will substitute 10 in place of h in our given equation.



Therefore, number of total miles biked will be 77.7 miles if Louis bikes for 10 hours.
Answer:
you use slope formula m=y2-y1/x2-x1
m=21-11/5-3=15.8
Step-by-step explanation:
so the 3 points you have are (-1,-9) (3,11) (5,21)
so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1
5 is x2 11 is y2
m=y2-y1/x2-x1
m=21-11/5-3=15.8
good luck :)
hopefully, this helps
have a great day !!
