Answers

Answer 1

Answer:

Answer:

70 × 6000 = 420000

Step-by-step explanation:

In this question, we need to write the product of two numbers 70 × 6000 using associative and commutative properties.

Two numbers are commutative if,

a × b = b × a

Two numbers are associative if,

(a × b) × c = a × (b × c)

Here, $70* 6000=(7* 10)* (6* 1000)$

$70* 6000=7* 10* 6* 1000$

Using commutative property as,

$70* 6000=7* 6* 10* 1000$

Now using associative property as,

$70* 6000=42* (10* 1000)$

$70* 6000=42* (10000)$

$70* 6000=420000$

So, 70 × 6000 = 420000. Hence, this is the required solution.

Monica uses the distributive property to write and equivalent expression to 63+28. Which expression did Monica write?A. 9(7+3)
B. 3(21+25)
C. 7(9+4)
D. 3(60+25)

Answers

The correct option is c, which is 7(9+4).

The distributive property is a property that helps us to know that when a number is multiplied by the sum of two numbers, it is equal to the sum of products of these two numbersmultiplied by the third number individually.

For example,

a(b+c) = ab+ac,

Now, as given Monica uses the distributive property to write an equivalent expression to 63+28.

therefore, the common ratio is 63, and 28 is 7.

Thus, 63+28 = 7(9+4).

Thus, the correct option is c, which is 7(9+4).

Answer:

Step-by-step explanation:

The highest common factor of 63 and 28 is 7, thus taking out 7 gives

63 + 28 = 7(9 + 4) → C
