Answer:
y= -1/2
x=3/2
Step-by-step explanation:
first isolate x
2x+4y=1
2x=1-4y
x=(1-4y)/2
subsitute it in the second equation
look at the pic
Answer:
Im not a 100% sure but my best guess would be the 3rd equation:
f(x) = (x - 1) (x + 3)
Please let me know if I was wrong, but i hope this helped you!
Answer:
1/ 5 and 2/3
cross multiple
example
1 2 = 10
/ x / = /
5 3 3
= 10/3
so it's 3 1/3 + 10 Mm
so may guess is
13.3333 infinite or 13.34 M
Dont know if its right but good luck
Step-by-step explanation:
Turn the ratio into a fraction
2in /25 mi
You want to have miles so you can flip the fraction and mutiply to cancel out the inches
(25mi / 2in) x 5in = (25 mi x 5in) / 2in
