100-16=84
84÷7=12
there are 12 students in the class because first you subtract 16 from 100 so you have that left then you divide that by 7 to find out how many students get 7 markers.
5(x² + 6x + 10)
That's the best way to factor it
28 = w/4 + 16....subtract 16 from both sides
28 - 16 = w/4
12 = w/4....multiply both sides by 4
12 * 4 = w
48 = w <===
