Given:
The number is -6.
To find:
The inverse with respect to addition of the given number.
Solution:
We need to find the additive inverse of -6, to get the inverse with respect to addition of -6.
We know that, the sum of a number and its additive inverse is 0.
Let the additive inverse of -6 be x. Then,
Adding 6 on both sides, we get
Therefore, the inverse with respect to addition of -6 is 6.
Point D is located between 35 and 40 so the possible answers are 36, 37, 38, and 39.
Point D is closer to 40 than 35, so we narrow down the option to 38 or 39.
39 would have been really close to 40, so Lara's statement is reasonable to say 38 is point D.
If Joe collected 94 stamps which are in April May and June, we could make an equation like this: A + M + J = All stamps
Plug in the values:
Isolate J:
Combine like terms:
He collected 33 stamps in June.
