Well 24=4*6, and 35=7*5 not 6, so 4/7 doesn't = 24/35, so no
Set up a proportion: 25/100 = 50/n where n = # of teens surveyed
Simplify fraction: 1/4 = 50/n
Cross multiply: n = 200
So 200 teens were surveyed.
A: 0 3 4 5 5 6 7 9 9 20
3 3 5 5 6 8 8 9 9
B: No, they are not symmetric
Answer:
40x = 1800 +25x
Step-by-step explanation:
So all angles within a triangle should add up to 180, 102+31= 133 then subtract. 180-133=47
X-47
