28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86 now we gonna find the value of x.
28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x.
28x≤114 divide 28 both of side to get value of x so it will be x≤4
Answer:
what are you talking about
Answer:
you got parallel. the one look like a x is insterseting
Step-by-step explanation:
60+40=100
Y=x^2-4x+8 and 4x+y=12 so y=12-4x, insert y in the quadratic to get
12-4x=x^2-4x+8
12=x^2+8
0=x^2-4=(x-2)(x+2)
So the solutions are x=2 and x=-2.
Answer:
I believe it is 120. Since you need 30 more feet to reach 50 feet below sea level, you divide by 30/2 because every 8 seconds it drops 2 feet and multiply 15 by 8 .
Not sure, but hope it helps! :)
