Answer:
48 burpees & 80 squats
Step-by-step explanation:
Let burpees= x
Let squat = y
For every 12 burpees Melinda did, she did 20 squats.
X/y =12/20
20x= 12y
X= 0.6y
Melinda did a total of 128 squats and burpees
X+y= 128
But x= 0.6y
0.6y +y= 128
1.6y= 128
Y= 128/1.6
Y= 80
X+y= 128
X+80= 128
X=128-80
X= 48
Answer:
ok so lets make this into a algrebra equation
22.2(mil)=0.34x
divide by 0.34
65294117.6471=x
x=65294118

I think y=2 there both on the 2 y intercept straight from each Other
Hi,
Let assume a the west side,
b the length of the north wall (i suppose the answer is smaller then the barn.
Cost of the fence= a*6+a*12+b*12=3000 $.
So 3a+2b=500==>b=(500-3a)/2
Area =a*b=a(500-3a)/2= 250a-3/2a²
Derivate the area ==> 250-3a=0
==> a=250/3 and b=(500-3*250/3)/2=125
Width=125 (feet)
Length=250/3=83.333 (feet)
The value should be -49. Hope this helps.
