We have that
<span>y=−2x+5 --------> equation 1
3x−4y=2---------> equation 2
</span><span>substituting 1 in 2
</span>3x-4*(-2x+5)=2--------> 3x+8x-20=2--------> 11x=22-----> x=2
y=-2x+5-----> -2*2+5-----> y=1
the solution is
x=2
y=1
Answer:
4000 people id.k any other method
Step-by-step explanation:
55% = men
100-55=45
45% = 1800 (not men)
divide both by 45
1% = 40
times both by 55
55% = 2200 men
2200 + 1800 = 4000
24 and 42, I got this by multiplying 5 and 2 then doing the same thing to 7 and adding the sums. I used this method to find the perimeter of 10 and 12 as well.
