Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
Marcia says she can use rounding to find the exact product of 6x75.
From the data:
Find the product of 6 and 75:
= 6x75
= 450
Find the product of 6 and 70:
= 6x70
= 420
Find the product of 6 and 80:
= 6x80
= 480
= 420 + 30
=450
= 450 + 30
= 480
The expression can be defined as the combination of constants and variables with mathematical operators.
Thus, Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.

Answer: Our required answer is
Step-by-step explanation:
Since we have given that
22c + 33d.
We have to use "Distributive property" to factor out the greatest common factor.
Since we know that 11 is the greatest common factor of 22 and 33.
So, it becomes,
Hence, our required answer is
Answer:
11 (2c+3d)

Got answer from khan academy
A) 24° B) 31° C) 66° D) 90°
All angles of a rectangle is right angled or 90°.
C) 66°
Given:
∠KJN= 24°
Thus,
∠MJN+∠KJN=90°
∠MJN = (90-24)°
∠MJN = 66°
Therefore, correct option is C.

Step-by-step explanation:
all the angles of the rectangle are right angle
therefore, angle MJK=90°
∠MJN+∠KJN=90°
∠MJN = (90-24)° = 66°
