Answer:
The answer is x = 13.
Step-by-step explanation:
first, move the constant to the right and change its sign, (+15)
3.75 x = 63.75 -15
next, subtract the numbers, (65.75 -15)
3.75x = 48.75
then, divide both sides of the equation by 3.75,
final answer, x = 13
1
the only number it can be is 1 as 1 + 
( the reciprocal of 1 )
thus 1 + = 2
2x-6 (2) is your equation. follow these steps, and you have to distribute 6 into 2 like this: 2x-12. you get negative 12 because -6 x 2 =-12. now you divide -12 by 2 which is -6. So -6=x
First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.
Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.
So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.
=24.16
