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
I believe the answer is c and have a very nice day
' x ÷ 3 ' is just another way to write ' 1/3 x ' ,
so your equation is y = 1/3 x .
The graph of that equation is a straight line,
going through the origin, with a slope of 1/3 .
Answer:
Approximately 7 cm
Step-by-step explanation:
Angle opposite to the required length:
180 - 90 - 43 = 47°
X/sin47 = 6.5/sin43
X = sin47 × 6.5/sin43
X = 6.970396615
