3.15. Just find the unit rate which is 1.5 and multiply that by 3
Answer:
C
Step-by-step explanation:
you add 15 and 10 witch gets you 25 and then you add 3 for the students that don't play either witch gets you 28 and then subtract 28 from 32, or just count up from 28 to 32 but you get the same answer.
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×

= 180° ×
∴ the size of the largest angle = 80°
Answer:
y= -x+10
Step-by-step explanation:
ok, so the basic formula is y=mx+b
m=slope and b= the intercept
the line crosses the y-axis at 10, so we know that 10=b. it is a downward going slope, so its negative. the formula for slope is rise/run, or in our case, fall/run. for every 2 it falls, it runs 2. that is -2/2, which can be simplified to -1. looking at the graph , it's hard to comprehend the question at first and it took me multiple times looking at the graph. I hope I helped some!
