Answer:
x=1
Step-by-step explanation:
f(x)=5x−4
f(x) = 1
1 = 5x - 4
Add 4
1+4 = 5x-4+4
5 = 5x
Divide by 5
5/5 = 5x/5
1 = x
Step-by-step explanation:
this is confusing.
first the description says "the internal dimensions".
and then it tells us the thickness of the tank walls (1cm).
so, I am not sure what the given numbers describe.
in any case, the volume is length × width × height.
so, either
48×38×32
or
46×36×31 (as for length and width we need to consider 2 walls, one on each end, for the height only one wall, as the tank is open and lidless.
whatever you choose, make sure to mark the result as cm³.
25(z + 2) = 125
apply distributive property
25z + 50 = 125
subtraction property of equality
25z = 75
division property of equality
z = 3
Answer is z = 3
I don't see any matching from the options.
