Answer:
x = 9
Step-by-step explanation:
given f(x) = 3x and f(x) = 27, then equating f(x) gives
3x = 27 ( divide both sides by 3 )
x = 9
First one is 2 and the other is 4
Answer:
(121 - x2) / (11 - x)
Step-by-step explanation:
well, if the water is coming out at 0.44 ft³ per minute, and you take a shower for 8 mins, that simply means you used 8*0.44 ft³, or namely 3.52 ft³.
what if you instead fill the bathtub with 0.45 yd³? is that more or less than 3.52ft³?
so then, there are that many ft³ in a yd³, so how many will there be in 0.45yd³ anyway?
well, then you'd use more water with the 0.45yd³ and some soap btw, by how much more? 12.15 - 3.52 = 8.63 ft³.
