Question

Solve the equations:

19 = h/3 - 8

0.6 + 0.8 = 1.4

PLEASE JUST ANSWER WITH THE ANSWER AND AN EXPLANATION

Answer 1

The second equation has nothing to solve.

Answer 2

Apparently it does? The question says: Solve the equation. Explain each step and identify the property used to reach each step

Answer 3

Do you know anything about solving equations.

Answer 4

?

Answer 5

I really do not want to sound dumb but no I know nothing.

Answer 6

\[
19 = \frac h3 - 8
\]In this case we want to solve for \(h\). To do that we want to isolate it. That will leave us with: \[
h=\ldots
\]Where \(\ldots\) is the value for \(h\). We can isolate \(h\) by doing operations to both sides.

Answer 7

For example, the first thing we can try to get rid of is the \(8\).

Answer 8

The opposite of subtracting \(8\) is to add \(8\).

Answer 9

So we add \(8\) to both sides. \[
19+8=\frac h3 -8 + 8
\]This is called the additive property of equality. It says we can add things to both sides and they will still be equal.

Answer 10

Then we simplify:\[
27=\frac h3
\]We know we have made progress because the \(h\) is getting closer to being isolated.

Answer 11

We need to get rid of division by \(3\), and the opposite operation for this is to multiply by \(3\). \[
27\times 3=\frac h3\times 3
\]This is called the multiplicative property of equality

Answer 12

Again, we have to simplify: \[
81 = h
\]

Answer 13

Does this make sense?

Answer 14

Yeah kinda. i'm going to read over it a few times to make sure I can know it better. Thanks for the help. But what about the second one? My book says that it needs to be solved?

Answer 15

\[

0.6 + 0.8 = 1.4
\]For this one, you just do addition, to simplify:\[
1.4=1.4
\]And so the answer is \(\text{true}\). There is no variable to solve.

Answer 16

Okay thanks. Have a nice day =D
