It is B because an equilateral triangle has all 3 sides that are equal
Answer: 8 -4/3 = 20/3
Step-by-step explanation:
3a + 2c = 275 .... t-shirt costs $3 per adult and $2 per child and <span>total money collected was $275
</span>
a + c = 100 ... the total number of adults (a) and children (c) who bought shirts was 100
so
3a + 2c = 275
a + c = 100 so a = 100 - c
substitute a = 100 - c into 3a + 2c = 275
3a + 2c = 275
3(100 - c) + 2c = 275
300 - 3c + 2c = 275
-c = - 25
c = 25
a = 100 -c = 100 - 25 = 75
so a = 75 (adults) and c = 25 (children)
answer
<span>Equation 1: a + c = 100
Equation 2: 3a + 2c = 275
25 children and 75 adults</span>
Midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(-5,5)....x1 = -5 and y1 = 5
(1,9).....x2 = 1 and y2 = 9
now we sub
m = (-5 + 1) / 2, (5 + 9) / 2
m = -4/2, 14/2
m = (-2,7) <=== ur midpoint of HI
