Answer:

4c + 4c + 16c + 90 = 360

Add the like terms

24c + 90 = 360

Subtract 90 when taking it to the other side of the equal

24c = 270

Divide 270 by 24 to get ur answer.

c = 11.25

Answer:

Yes, the answer is 11.25

Step-by-step explanation:

This sum involves solving for the unknown.

We will need to solve the algebraic equations first.

This in simple terms means collecting all like terms:ie

4c+4c+16c

&90 and 360

after collecting the like terms we should add or subtract them(based on the sign)

4c + 4c+ 16c= 24c

24c+90=360

We'll now remain with the number 90 which is odd one out. We'll need to collect it's like term which is 360. In Mathematics, if you move a number from it's original side to another side, the calculation sign will turn vice versa.

24c=360-90

Note that it was +90 and now it's -90

The sum will now be:

24c=270

Inorder to get the result we shall divide bith side by 24

24c/24c=270/24

24 divided by 24 is 1 Which leaves the sum270÷24

Which leads to the answer 11.25

X/4 - 12 = -18
x/4 -12 +12 = -18 + 12
x/4 = -6
x/4 times 4 = -6 times 4
x = -24

Check
-24 divided by 4 = -6 -12 = -18

100 points+Brainliest for correct answer

Answer:

The electron moved down to an energy level and has an energy of

$10.92 \times 10^{-19} \textsf{J}$

Step-by-step explanation:

$\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}$

$\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}$

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

$\triangle E=E_2-E_1$

$\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1$

$\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}$

$\implies E_1= 10.92 \times 10^{-19}$

Answer:

The electron moved down to an energy level and has an energy of

$10.92 \times 10^{-19} \textsf{J}$

I need help with number 17 please, and show work. I keep getting different answers. 1

Alecsey [184]

$\frac{(x+1)(x-1)}{(x+1)(x-1)(x+1)} - \frac{2(x-1)}{(x+1)(x-1)(x+1)} + \frac{3(x+1)}{(x+1)(x-1)(x+1)}$

= $\frac{x^2-2-2x+2+3x+3}{(x+1)(x-1)(x+1)}$
= $\frac{x^2+x+4}{(x+1)(x-1)(x+1)}$ is what I got.
