Answer:
x = 7.2
Step-by-step explanation:
Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.
Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}
(Assuming x is greater than 1.7}
Given that, x + 3.8 = 2(x - 1.7)
⇒ x + 3.8 = 2x - 3.4
⇒ x = 7.2 (Answer)
The answer or result of multiplication is called the Product.
The function shows that the cost of hotdogs is 1.75 and the cost of hamburger is 1.5.
<h3>How to calculate the information?</h3>
Let hotdogs = h
Let hamburger = x
The expression will be:
h + x = 3.25
h + 7x = 12.25
Subtract the functions
6x = 9
x = 1.5
Therefore, hot dogs will be:
= 3.25 - 1.5
= 1.75
