The correct answer is C, 4:5 would be equivalent to 24/30, because 30 divided by 5 is equal to 6, so you would multiply the numerator and denominator by the same number.
If 1 gallon weighs 8.34 lbs.....then 6 gallons weighs (6 * 8.34) = 50.04 lbs
9.
9 squared is 81. 81+4=85. 85 is divisible by 5.
x+3(x-5)=9 Substitute y=x-5 into every y into the first equation and solve for x
x+3x-15=9
4x=24
x=6
Substitute x into any equation and then solve for y.
y=(6)-5=1
x=6, y=1
Hope that helps!
