Answer:
The value of x for the given expression is
Step-by-step explanation:
Given as :
<u>The expression is written </u>
3
- 1
× x = 1
Or, 1
× x = 3
- 1
Or,
× x =
- 1
Or,
× x =
- 1
Or,
× x = 
Or,
× x = 
∴ x = 
Or, x = 
I.e x = 
So, The value of x = 
Hence The value of x for the given expression is
Answer
Answer:
8 boxes approx
Step-by-step explanation:
Step one:
given data
One box contains 48 bars
Required
The number of boxes needed for a total of 338 students if each person is to get at least one bar.

this can be gotten by dividing 338 by the number of the bar in a box
= 338/48
=7.04
=8 boxes approx
He needs to purchase at least 8 box
Answer:
0.10x + 0.13y = 10780
x + y = 100000
x = 74000 --------------10%
y = 26000 --------------13% (more risky)
First let's define the variables of the problem:
t: Tip
b: dinner bill.
We write the inequality based on the following proposition:
"Maria would like to leave a tip (t) of at least 15% of her dinner bill (b)"
We have then that the inequation is:
t> = 0.15b
Answer:
An inequality best could be used to find the amount of the tip Maria would like to leave is:
t> = 0.15b
