The domain of a function is the set of values that can be used for x.
Here, x represents the number of tacos.
He can order no taco, so x = 0.
He can order 1 taco, where x = 1.
He can order 2 tacos, so x = 2.
He cannot order a fraction of a taco, so x cannot be a mixed numeral.
He can order as many tacos as he wants, so x can be any whole number, 0 to infinity.
The domain is all whole numbers.
x = 125
Multiply both sides by 5:
x/5 X 5 = x
and
25 X 5 = 125
so you're left with:
x = 125

You could try rounding up to 0.292 first and try guessing it it gets to 73/250 which you could guess into 70/240.
Since it is about only the outer part of the aquarium which is made of glasses we need to calculate the total surface area.
Surface area of the base = 4*3 = 12 square feet
Surface area of the shorter length of wall = 3*2 = 6 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
6*2 = 12 square feet
Surface area of the longer length of wall = 4*2 = 8 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
8*2 = 16 square feet
Therefore the total surface area that need to be covered with glasses
12+12+16 = 40 square feet
T + S + R = 180
R = 180 - (T + S)
T + S = 68 + 76 = 144
So R = 180 - 144 = 36
<R = 36
