Y = 7x + 12.....x = number of tickets and y = total cost
and there are 4 tickets ordered (Frank and 3 friends)...so x = 4
y = 7(4) + 12
y = 28 + 12
y = 40 <=== so he paid 40 bucks for them
4 is not a factor of 30 because the factor of 30 is:
2*15
6*5
3*10
1*30
Answer:
125°
Step-by-step explanation:
The angle marked f° is called an "external angle" of the triangle. Relative to that external angle, the two internal angles marked 44° and 81° are called "remote internal angles." Because f° and the adjacent internal angle are supplementary (add to 180°), and because all of the internal angles of the triangle add to 180°, the measure of f is equal to the sum of the remote interior angles:
f° = 44° + 81°
f° = 125°
Answer:
a) The mass of a box of bolts is greater.
b) 3/20 kg
Step-by-step explanation:
a) Firstly, you have to make the denominators of the two fractions the same (by finding the LCM of the denominators).
The LCM of 4 and 5 is 20.
Converting 3/4 into denominator 20:

= 15/20
Converting 3/5 into denominator 20:

= 12/20
Now comparing the numerators:
15 > 12
Hence,
3/4 > 3/5
b) Difference of the boxes can be done by subtracting the numbers with the same denominator:
15/20 - 12/20
= 3/20 kg
