Okay so you would take 19.50 and add the 5 dollar insurance giving you 24.50. Then you’d take the 24.50 and multiply it by 12 giving you 294 dollars

The sum of 7 and three times a number is at least 13
Yuki888 [10]

Answer:

7 + 3x ≥ 13

Step-by-step explanation:

The best way to write this is to truly understand what each of the terms mean. The sum means that multiple terms are added together, which means that 7 and 3 times a number will be added together.

Next, the term three times a number just means 3x. So as of now, we have 7 and 3x being added together.

Finally, the term at least 13 means that the 7 + 3x is greater than or equal to 13. Once everything is put together, you get a final inequality of 7 + 3x ≥ 13.
