Step-by-step explanation:

8x-3x = 18-3(like terms)

or,5x = 15

or,x=15/5

or,x=3

Answer:

x = 3

Step-by-step explanation:

in order to solve for the value of x in the expression

8x + 3 = 3x + 18

we are going to simply combine the like terms then later evaluate for the value of x

8x + 3 = 3x + 18

8x + 3 - 3x = 18

8x -3x = 18 -3

5x = 15

divide both sides by the coefficient of x

5x/5 = 15/5

x = 3

therefore the value of x in the expression

8x + 3 = 3x + 18 is equals to 3

Problem PageQuestion The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate paramet

asambeis [7]

Answer:

t = 1.51

Step-by-step explanation:

Exponential Model

The exponential model is often used to simulate the behavior of a magnitude that either grow or decay in proportion to the existing amount of that magnitude.

The model can be expressed as

$M=M_oe^{kt}$

In this case, Mo is the initial mass of the radioactive substance and k is a constant which value is positive if the mass is growing or negative if the mass is decaying.

The value of k is not precisely given in the question, we are assuming $k=-0.2$
