Question

2 = (2/5 + 2/6)t

Answer 1

Reverse the equality in \(2 = \frac{11 t}{15}\) in order to isolate t to the left hand side.

Answer 2

So what's equivalent to \(2=\frac{11t}{15}\)?

Answer 3

Seems like this fine young lady is helping you, cooperate with her.

Answer 4

sorry

Answer 5

new to this website and learning the ropes

Answer 6

im sorry i dont understand how you simplified it

Answer 7

I didn't, I'm helping you isolate the variable first :) What's the equivalent of \(\large 2=\frac{11t}{15}\)

Answer 8

ok i got a little lost

Answer 9

it started with 2=2/5t+2/6t

Answer 10

and i understand we were trying to simplify/isolate the variable

Answer 11

Teach her about common denominators first.

Answer 12

1. there is no need to be rude

Answer 13

pfffffffft

Answer 14

calling me a nerd

Answer 15

saying i need education

Answer 16

and yes i do

Answer 17

Oh, that's just the way for you to find a common denominator for the two fractions.. He never called you a nerd..?

Answer 18

He called me a nerd in the mathematics chat box

Answer 19

You don't know what a 'nerd' is do you? Its not something you call a stubborn person. If it were- your username would be nerd.

Answer 20

Much insult

Answer 21

Such wow

Answer 22

(nice one regrets opening this website)
(mean one does not)

Answer 23

i just wanted some help... :(

Answer 24

(And there are two people right now sharing the same laptop, so when we say nice one or mean one, we are talking about the person who is typing. As you can tell, the mean one is hecka sarcastic and has no regrets.)

Answer 25

ok so in all this i got 2=22/30t

Answer 26

is that right?

Answer 27

Hm.
Simplify the following:
(2/5+2/6) t
Reduce 2/6 to lowest terms. Start by finding the GCD of 2 and 6.
The gcd of 2 and 6 is 2, so 2/6 = (2×1)/(2×3) = 2/2×1/3 = 1/3:
(2/5+1/3) t
Put the fractions in 2/5+1/3 over a common denominator.
Put 2/5+1/3 over the common denominator 15. \(\frac{2}{5}+\frac{1}{3} = \frac{3×2}{15}+\frac{5}{15}:\)
\(\frac{3×2}{15}+\frac{5}{15 t}\)
Multiply 3 and 2 together.
\(3×2 = 6:\)
\((\frac{6}{15}+\frac{5}{15}) t\)
Add the fractions over a common denominator to a single fraction.
\[\frac{6}{15}+\frac{5}{15} = \frac{6+5}{15}:\]\(\frac{6+5}{15 t}\)
Evaluate \(6+5\).
\(6+5 = 11:\)
Sorry for being sporadic with the equations, I get lazy.

Answer 28

And that leaves you with the simplified \(\frac{11t}{15}\)

Answer 29

the lesson didnt say anything about GCD

Answer 30

ill send the whole thing

Answer 31

Shannon and Macie are raking leaves to earn some money. Shannon can rake 2 lawns that are about the same size in 5 hours. Macie can rake 2 lawns that are about the same size in 6 hours. How long would it take both girls to work together to rake 2 lawns? Write and solve an equation for this situation. Explain how to set up the equation, using w = rt.

Answer 32

I know :) To find \(t\), the easiest thing to do is to simplify the fraction :)

Answer 33

okay

Answer 34

So, can you tell me what's equivalent to \(2=\frac{11t}{15}\)?

Answer 35

would you multiply 15 then cancel out?

Answer 36

GCD=Greatest Common Denominator. Thanks for helping by the way jess.

Answer 37

I know what GCD is, but the question said nothing about it; if you read it that is.

Answer 38

No, you just switch out 2 and \(\frac{11t}{15}\). So the equivaent equation is \(\frac{11t}{15}=2\) No prob, Bob.

Answer 39

Now, just multiply both sides by a constant. What do you think the constant would be?
