Sue of estimates = 6200
Step-by-step explanation:
can be estimated as which is
Similarly can be estimated as which is
∴ Sum of estimates =
Answer:
It is an isosceles triangle so the 6 is not correct. We can use the Pythagorean Theorem and 64 does not equal 36+16.
Step-by-step explanation:
Answer: The answer is (22, 15).
Step-by-step explanation: Given that 'x' represents the number of cars Leonard has and 'y' represents the number of cars Liam has.
Then, according to the given information, we have
Multiplying the first equation by 2 and adding to the second equation, we have
So,
Therefore, Leonard has 22 cars and Liam has 15 cars.
Thus, (22, 15) is the solution to the given system.
I think in commutative properties of multiplication:
70 x 6000 = 70 x 6000
420,000 = 420,000
I don't know associative properties, only commutative properties. Sorry :(
