1/2x + 42 = 4x
-1/2x -1/2x
------------------------
42 = 3.5x
/3.5 /3.5
------------------------
12 = x
the number is 12
explanation: 42 more than 1/2 of a number can be written as 1/2x + 42
four times a number can be written as 4x.
42 more than 1/2 of a number is equal to 4 times a number. So 1/2x + 42 = 4x.
Hope this helps :)
Answer:
B
Step-by-step explanation:
It's not going negative you can tell by the line it has y-intercept and the last on didn't the other ones have aa negative. If you have a problem with these kinds of equations just do process of elimination and you'll be fine also here's the answer to another question
Here the monthly payment is $1500.
Now 12% of this payment is interest.
Now 12% of 1500 = 0.12 ×1500 = $180
But this is the interest for one month.
As deductions are made in the financial year.
So the interest needs to be calculated for the whole year which is 12 months.
Now the interest for the whole year is 180 × 12 = $2160.
Option C) is the right answer.
