Estimate the sum or difference 3 2/5 - 5/8

3

Step-by-step explanation:

I would estimate 3 2/5 to 3 1/2 and 5/8 to 1/2.

Therefore, 3 1/2-1/2 would be 3

However there are many different ways to estimate.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
