Answer:

(1) 820

(2) 1920

Step-by-step explanation:

(1) solving 20 x 41, using associative property.

20 * 41 = (2 x 10) x 41 = 2 x (10 x 41)

= 20 x 41 = 2 x 410

= 820 = 820

(2) distribute 32 as 30 + 2 and solve.

60 x 32

= 60 x (30 + 2) = 60(30) + 60(2)

= 1800 + 120

= 1920

5 hours long would it take the faster maid cleaning alone.

What is a linear equation in math?

A linear equation only has one or two variables.
No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.

Suppose, time taken by faster maid be x , hours.

So, time taken by slower maid ,

$x_{2} = 4x_{1}$ ( 4 time faster maid )
