|2x - 3| +4 = 17
Subtract 4
|2x - 3| = 13
Whatever is inside the Absolute must equal 13. Imagine it in our head, x = -5 is one solution, because it creates |-13| which becomes positive. Then we have x = 8, because that forms |16 - 3| = |13| = 13
The sales tax rate is 6.5%
Fourteen is 28% of B) 50
Why, you ask? Let's see -
Let the unknown number be n, for 'number'.
Let's put the unknown n next to 28%
.28n% = 14
(Think, what times .28 equals 14? Look below to find out! ↓ )
Let's now do the opposite of the actual equation - divide the two known numbers by each other -
.28 ÷ 14 = 50
When in doubt, check your answer:
To check this, we would do the opposite - Multiplication
Multiply .28 by 50 to get 14 (At least you should get 14)
.28 × 50 DOES EQUAL 14! We were right! :D

I do believe on the information given that this is the answer
Answer:
96:144
Step-by-step explanation:
Since there are 240 students and the known value is 96 students buying lunch, you simply subtract the two numbers.
240 - 96 = 144
There are 144 students bringing bag lunch.
The ratio is asking students purchasing lunch to students bringing a bag lunch, which would be 96:144
The simplified answer is 2:3
To get this, divide 144 by 96
This, in turn, would give you in answer of 3/2 which can be inversed to get the right answer
