Answer:
39-6a
Step-by-step explanation:
(4 - a) - 5(a - 7) Distribute the -5 throughout (a-7)
4 - a - 5a + 35 Combine like terms
4 + 35 - a - 5a
39 - 6a
The probability of the die rolling a 6 is '1 in 7' or 14% as there are 7 sides all with an equal chance of landing on that number.
Hope this helps!
Answer:
- 27
Step-by-step explanation:
Evaluate from the ' inside out ' , that is
Evaluate g(2) then use this value to evaluate f(x) then use this value to evaluate h(x)
g(2) = 4(2)² - 9 = 4(4) - 9 = 16 - 9 = 7, then
f(7) = 7 + 7 = 14 , then
h(14) = - 2(14) + 1 = - 28 + 1 = - 27
No the 8/12 is the bigger one
30 minutes: 72km
50 minutes: 120km
1 hour = 60 minutes: 144km
