Show all of your steps and solve

0.25r - 0.125 + 0.5r = 0.5 + r

@texaschic101

Answer 1

Make sure you show all of the steps for my benefit

Answer 2

For your maximum benefit you should TRY to do it yourself.

Answer 3

first combine like terms

Answer 4

ok hold on

Answer 5

just on the left side of the equal sign, there are no like terms on the right side

Answer 6

do you know what like terms are ?

Answer 7

0.25r - 0.125 + 0.5r = 0.5 + r
-0.5r -0.5r

0.20r - 0.125 = 0.5 + r

Answer 8

let me show you....
.25r - .125 + .5r = .5 + r
on the right side of the equal sign, add your r terms. (.25r + .5r)

Answer 9

it should look like this after adding your r terms...
.30r - .125 = .5 + r
do you understand ?

Answer 10

yes

Answer 11

now you want to get your r terms on one side and everything else on the other side. So you want to move the r term on the right side to the left side. Do you know how to do that ?

Answer 12

no

Answer 13

ok.....to do that, you do the opposite of what the r says. I know that is confusing. I will try to explain. The r on the right side says + r so do the opposite and -r on both sides. This will cancel out the r on the right side. So subtract r from both sides

Answer 14

it should look like this....
.30r - .125 - r = .5 + r - r
as you can see the r on the right side cancels out
Does that make sense to you ?

Answer 15

yes

Answer 16

now to make things easier combine your like terms

Answer 17

but remember, the r is 1r. So when combining like terms on the right side, remember this

Answer 18

am I confusing you ? I am not the best at explaining things

Answer 19

yes lol Im kind of confused it would be easier if you stacked your steps it would make it easier on me

Step 1
step 2
step3

Answer 20

.30r - .125 - r = .5
combine like terms
do you know what .30r - 1r equals ?

Answer 21

no

Answer 22

ok .30r - 1r
subtract .30 from 1 and put a negative sign in front

Answer 23

.70

Answer 24

you forgot the negative but good job...you just combined like terms...
so now we have :
- .70r - .125 = .5
have I lost you, or do you understand ?

Answer 25

im understanding but at the end will you work it out without explaining it helps

Answer 26

at the end I will.
now we want the r on one side and everything else on the other side. So we have to move the .125 to the other side. So we will do the opposite. It says -.125 so we have to +.125 (add .125 to both sides).
Can you do that ?

Answer 27

.625

Answer 28

-.70r -.125 + .125 = .5 + .125......it is not 5, it is .5 do not forget your decimal. Combine like terms.

Answer 29

remember the .125's cancel each other out on the right side.

Answer 30

I didn't forget the decimal try adding .125+.5 on a calculator it adds up to .625

Answer 31

you right...my mistake.....
so what is your equation once you combine like terms

Answer 32

-70r = .625

Answer 33

correct. You are doing good. Now we want r by itself. It is saying multiply, so we do the opposite and divide.
-.70r/-.70 = .625/-.70
can you do this ?

Answer 34

.89

Answer 35

the -.70's on the right side, when divided = 1, so your left with 1r or just r.
so you have r = - .892 or -.89, it depends on how many decimal places you want to go to. Remember a positive divided by a negative equals a negative.

Answer 36

I will write the problem out for you now, give me a second

Answer 37

I think we messed up when we done .25+.5

Answer 38

gotta go walk my dog ill be back

Answer 39

.25r - .125 + .5r = .5 + r
.75r - .125 = .5 + r
.75r - r = .5 + .125
-.25r = .625
r = .625/-.25
r = - 2.5

Answer 40

let me check it....
.25r - .125 + .5r = .5 + r
.25(-2.5) - .125 + .5(-2.5) = .5 + (-2.5)
-.625 - .125 - 1.25 = .5 - 2.5
-2 = -2 (correct)

r = -2.5
sorry about the mistake earlier.
