There are 50 equally sized regular apartments in a housing estate and one which is half the size of regular apartment, each apartment is occupied by 4 tenants depending on the size, hence the half sized apartment will have only two occupants. 50 1/2 × 4/1 = 202

50 refers to the number of regular sized apartment ; 1/2 means the apartment after 59 is half the size of the regular ones.

4 refers to the number of occupants in each apartment depending on size.

step-by-step explanation:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
