Required number is 17.
<h3>Justification:</h3>
<u>We need to find the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively</u>.
Hence, we need to find the HCF of 3 numbers (398-7), (436-11) and (542-15).
Hence,
- 398 - 7 = 391
- 436 - 11 = 425
- 542 - 15 = 527
Now, you can find the HCF(391, 425, 527) = 17
<u>Hence, the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively is 17</u>.
A. Each sector of a circle graph shows a category and the relative size of the category .
so you need to get "a" alone
a-2+3=-2
subtract 3 from both sides
a - 2 = -2-3
a - 2 = -5
then add two to both sides
a = -3
as your answer
