<u>ANSWER:</u>
The solution set for the inequality 7x < 7(x - 2) is null set 
<u>SOLUTION:</u>
Given, inequality expression is 7x < 7 × (x – 2)
We have to give the solution set for above inequality expression in the interval notation form.
Now, let us solve the inequality expression for x.
Then, 7x < 7 × (x – 2)
7x < 7 × x – 2 × 7
7x < 7x – 14
7x – (7x – 14) < 0
7x – 7x + 14 < 0
0 + 14 < 0
14 < 0
Which is false, so there exists no solution for x which can satisfy the given equation.
So, the interval solution for given inequality will be null set
Hence, the solution set is
Answer:
(c) 10 phones
Step-by-step explanation:
The mean is the sum divided by the number of contributors:
(12 +10 +9 +5 +14 +10 +10)/7 = 70/7 = 10
The mean number of phones sold for the week was 10 phones.
Answer:
(6x-12)+(8x-4)=180
14x-16=180
14x=196
x=14
Step-by-step explanation:
<h3>
<u>Explanation</u></h3>
- Convert the equation into slope-intercept form.
where m = slope and b = y-intercept.
What we have to do is to make the y-term as the subject of equation.
From y = mx+b, the slope is 3.

<u>Answer</u></h3>
Answer:
80%
Step-by-step explanation:
Original price =$75.00
Sale price =$60.00
The percentage discount can be calculated by dividing the sale price by the original price multiplied by 100%.
So % discount = $60.00/$75.00 x 100%
0.8 x 100%
80%
Janelle got the dress on a discount of 80%.
This is so because she got the dress for a price less than the original price
