Answer:
I kinda did a lil of this in my head so i might not be 100% correct, but i would say the bigger group is 20 and the smaller group is 10
Step-by-step explanation:
x and y are roughly in a linear relationship.
when x increases by 2 units, then also y increases by more or less 2 units.
when x increases by 3 units, then also y increases by more or less 3 units.
it is not precise, but a good approximation model.
Answer:
When x = -2 or when x = 7
Step-by-step explanation:
x+2 is a factor in the denominator. If x = -2, the factor becomes zero.
x-7 is a factor in the denominator. If x = 7, the factor becomes zero.
We can't have zero as a factor in a denominator because division by zero is not defined. It doesn't have any meaning.
Answer: Total number of pairs =872
Step-by-step explanation:
Since we have given that
Number of pairs of skates during the month of April =218
Number of pairs of skates during the month of May =3 × 218=654
As we know that total means altogether in which we perform the additive operation.
Total pairs of skates the skating rent during April and May = 218+654=872
∴ Total number of pairs =872
