Marcia says she can use rounding to find the exact product of 6x75. She says that since 75 is halfway between 7 tens and 8 tens the exact product of 6x75 must be halfway between 6x70 and 6x80 is she correct

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.
What is an arithmetic operation?
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.

6x70=420
6x80=480
So 420+30=450
450+30=480

so first we find the difference and then subtract that from 70
use parenthases so
difference of 20 and 13 is equal to (20-13)
subtract that from 70
70-(20-13)
so you would do the pemdas and get 7 for the inside parethasees then do
70-7=63
equation is 70-(20-13)

Answer:
A. 1265 cm²
Step-by-step explanation:
You want the area in square centimeters of a 14-inch square tile.
Area
The area of a square is the square of the side length. The side length in cm is ...
(14 in)×(2.54 cm/in) = 35.56 cm
Then the area of the square is ...
A = (35.56 cm)² = 1264.5136 cm²
The area of the tile is about 1265 square centimeters, choice A.
