Answer:
About 8 pounds and 8 ounces
Step-by-step explanation:
I'm not 100% sure but I'm pretty sure it's that.
X=2.5
Step-by-step explanation:
0.5=1/2
5/2 = 2.5
Yes, very fun, not
ok
one way is table or
solutions amount x and y
x+y=500
x=25%
y=50%
0.25x+0.5y=0.35(500)
we have
x+y=500
0.25x+0.5y=0.35(500)
0.25x+0.5y=175
solve
multiply second equation by 100
25x+50y=17500
divide everybody by 25
x+2y=700
now we have
x+y=500
x+2y=700
multiply first equation by -1 and add to second equaiton
-x-y=-500
<u>x+2y=700 +</u>
0x+1y=200
y=200
sub
x+y=500
x+200=500
x=300
300L of the 25% and 200L of the 50%
Did you figure this out ever because if not than i can help you
<span>3x + y= 17 (a)
4x + 2 y = 20 (b)
Multiply (a) by 2:
6x + 2y = 34 (a)
4x + 2y = 20 (b)
make: (a) - (b)
2x = 14 -----> x =7
-------------------------------
Replace the value of x = 7 in one of anterior equation:
</span>3x + y= 17
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4
