Step-by-step explanation:
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
17+(10X)= 21+(5x) is the equation
17 +(10x1)= 21+(5x1)
17+10=21+5
27=27
So your answer is it takes 1 mile per day
Hope its right lol
Answer:
less
Step-by-step explanation:
4x+5 = 8x - 11
4x - 8x = -11 - 5
-4x = -16
x = 4
4x+5 = 4(4) +5 = 21
8x - 11 = 8(4) - 11 = 21
<RST = 21 + 21 = 42
answer
<RST = 42 degrees
