Answer:
23
Step-by-step explanation:
Compatible numbers : numbers that are easy to add, subtract, multiply, or divide mentally. They are close in value to the actual numbers, although they do not necessary need to be rounded numbers.
-138 is close to -137.56
-6 is close to -6.12
Divide the top and bottom by -2:
Divide the top and bottom by 3
If this is too difficult to divide mentally, you could use -140 and -7:
As 2 x 7 = 14, then 20 x 7 = 140, so the answer is 20.

Answer:
x = 4
Step-by-step explanation:
The given equation is :
6 - x =2
Put x = 1 and see LHS is equal to RHS or not.
So,
6-1 ≠ 2
Put x = 2 and see LHS is equal to RHS or not.
So,
6-2 ≠ 2
Put x = 3 and see LHS is equal to RHS or not.
So,
6-3 ≠ 2
Put x = 4 and see LHS is equal to RHS or not.
So,
6-4=2
2 = 2
So, the solution of the given equation is x = 4.
Answer:
74 , 76 , 78
Step-by-step explanation:
Let the first of your number be x, As you are only looking at even integers, the next consecutive even integer would be x+2 and the consecutive even integer after that would be x+4. The sum of these three even integers results in 228 so we can say that:
so the first even number is 74 then the second consecutive even number is 76 then the third consecutive even number is 78
It’s 11 i think. i’m not positive but i think that’s it.
