In a chemical process between 77g and 85g of carbon is added to a mixture let c be the amount of carbon write an absolute value inequality describing the amount of carbon added

Absolute value inequality is given as ... (1)

Opening the absolute sign, we get

or

Combining the inequalities we get -

Add, A on both sides.

It is given that, C is between 77 gm and 85 gm

Hence , ... (2)

.... (3)

solving equation (2) and (3)

A = 81 and B = 4

Plug the values of A and B in equation 1.

Absolute value equation is

no not all of them.

step-by-step explanation:

some of them have a square base.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
