Let
x-------> bags of <span>popcorn
</span>y-------> bags of hotdogs
we know that
2.50x+3y=200-------> equation 1
x=2y--------> equation 2
substitute 2 in 1
2.50*[2y]+3y=200--------> 5y+3y=200------> 8y=200-----> y=200/8
y=25
x=2y-----> x=2*25-----> x=50
the answer is
50 bags of popcorn
25 bags of hotdogs<span />
Answer:
a
Step-by-step explanation:
I already answered this, but I guess it didn't go through
If angle AXB is complementary with angle CYD and FZE
then their sum leads to 90°
∠AXB+∠CYD=90
∠AXB+∠FZE=90
if ∠AXB=20 then both∠ CYD and∠FZE=70°
Answer: 1/4 or 25%
Step-by-step explanation:
The chance of flipping tails is 1/2, so you multiply 1/2*1/2 (for the 2 flips) to get 1/4 (1/2^2=1/4).
So you have to isolate the variable c
to do so multiply both sides by 2
2*(6/15) = c
you can do the rest
Hope this helps ;)
