Answer:
$12.50
Step-by-step explanation:
Let x = the cost of the food without the delivery fee.
The delivery fee can be represented as 0.10x.
Keep in mind that the cost of the food plus the delivery fee equals $13.75.
Therefore, your equation will look like: 13.75 = x + 0.10x
x + 0.1x = 1.10x
So, 13.75 = 1.10x
This means that x = 13.75/1.10
x = 12.5 = $12.50
Answer:
so this is a pretty simple question 559x15=x
Step-by-step explanation:
what we can do to make this equation more easy is do 559x10= 5590
and then just multiply 559x5=2795
2795+5590=8385
so in conclusion he needs $8385

Answer:
41. <u>(2) x² - 3x - 4 =0</u>
Step-by-step explanation:
<u>Question 41</u>
<u>Standard form of polynomial</u>
- x² - (sum of roots) + product of roots = 0
- <u>(2) x² - 3x - 4 =0</u>
The inequality you require is
The number of bottles left at the end of each day is 48 - 3x. So it is:-
48 - 3x < 10
Solving the inequality to find the last part of question:-
-3x < 10 - 48
-3x < -38
x > 38/3 = 12 2/3
So answer is 13 days.
