Answer:
A
Step-by-step explanation:
y= x+1 at the same time y=4x+5
x+1= 4x+5, so answer is A
Answer:
a - 30.2
b - 271.8
Step-by-step explanation:
60/4=15
60/3=20
9+6.45+2.4+8.15+4.2=30.2
30.2x9=271.8
Total money Marcus has = $28
Money spent to buy a notebook = $3.75
Money left now = 
Money needed to be saved = $11.25
So, the amount of money Marcus can spend = 
Cost of a packet of chips = $1.30
The inequality to determine the maximum number of chips he can buy is:
Let the number of chips Marcus can buy = x
As he cannot spend more than $13 to buy chips so equation becomes:

Solving this we get

Hence, Marcus can buy a maximum of 10 packs of chips and save $11.25
0 and 5 can be in the one's place of a number that has 5 as a factor.
Answer: just simplify condense it then your answer will be log(16)
