.
B) 20 Multiplied by 15 multiplied by 9 is equal to 2,700cm cubed
The question lacks the total number of socks and belts altogether. Thsi value is necessary so that we can create another equation to solve the unknowns.
if assumed that a = b, the answer, a = b = 2.43 will not make sense since you cannot buy 43% of a pair of socks. Completely define the conditions so that the answer can be obtained.
by trial and error, 3 pair of socks and 2 belts would be a sensible answer
Answer:
401 r 20
Step-by-step explanation:
Hello :
<span>x²- y = 3 ...(1)
x - y = -3 ...(2)
by (2) : y = x+3
subqct in (1) : x²-x-3 = 3
x²-x-6 =0
(x+2)(x-3) = 0
x+2 =0 or x-3 =0
x=-2 or x=3
if x = -2 y = -2+3 = 1
if x=3 y =3+3 = 6
two solutions : ( -2, 1) , (3,6)</span>
