Adding fractions 1/6+2/3=

Mathematics
2 answers:

Answer:

\frac{5}{6}

\frac{1}{6} + \frac{2}{3} is equivalent to \frac{1}{6} + \frac{4}{6}.

This is because \frac{2}{3}=\frac{4}{6}

The rule is, in order to add fractions, your denominators must be equivalent. In other words, you must have the same denominator for both fractions.

<em>Now what do we do? We add!</em>

\frac{1}{6} + \frac{4}{6} =\frac{5}{6}

This is because 4 + 1 = 5.

Your answer is \frac{5}{6}.

I hope this helps!

Answer:

\frac{5}{6}

Step-by-step explanation:

First, we need to make our denominators match.

Since 3 is evenly divided by 6, we can multiply just one term to get a common denominator.

Multiply 2 by 2, and get 4, then we multiply 3 by 2 and get 6.

1.  \frac{2 × 2}{3 × 2} = \frac{4}{6}

\frac{1}{6} + \frac{4}{6}

---------------------------------------------------------------------------------------------

Since our denominators match, we can add the numerators.

1 + 4 = 5

Now we have an answer:

\frac{5}{6}

Pre Algebra

Answer:

A. 36

B. 3.5

Step-by-step explanation:

To solve for the first equation, we could represent the hot dogs as h(1.75-.50), since they are losing .50 cents for each hot dog, <em>h,</em> they make.

Since they want to know how many hot dogs they have to sell to equal the amount of money they spent, we can represent it as an equal sign.

Now all we have to do is add the constants. Add 12 to our overall equation and subtract 57, since the <u>received</u> $12 in donations and <u>lost</u> $57.

Our equation is 12+h1.75=57+.5h We can just put all of the negative numbers on one side and the positive numbers on the other to find out when they will be equal.

First, subtract 12 from 57.

h1.75=45+.5h

Now subtract .5h from both sides.

h1.25=45

Finally, divide both sides by 1.25.

h=36.

They will have to sell 36 hot dogs.

If they want to sell halve the hotdogs for the same price, simply multiply the current price by 2.

The hotdogs will have to cost $3.5.

Hope this helps!

In Exercise, find the derivative of the function.<br> y = 3ex - xex
nevsk [136]

Answer:

the question is incomplete, the complete question is "find the derivative of the function y=3e^{x}-xe^{x}"

answer: \frac{dy}{dx}=(2-x)e^{x}.

Step-by-step explanation:

From the equation,  y=3e^{x}-xe^{x}, we approach the question using the differentiation of a product and differentiation of a sum simultaneously,

the differentiation of a sum is express as

f(x)=u(x)+v(x)+.....w(x) then

\frac{df(x)}{dx}=\frac{du(x)}{dx}+\frac{dv(x)}{dx}+...\frac{dw(x)}{dx}.\\

For the differentiation of a product we have

 f(x)=u(x)v(x), then

\frac{df(x)}{dx}=\frac{dv(x)}{dx}u(x)+\frac{du(x)}{dx}v(x)

hence if we go by the formula we arrive at

for   y=3e^{x}

let u(x)=3 hence du/dx=0 and

v(x)=e^{x} and \frac{dv(x)}{dx}=e^{x}

hence \frac{dy}{dx}=3e^{x}+0e^{x}\\\frac{dy}{dx}=3e^{x}---equation 1\\

Also for y=-xe^{x}\\\frac{dy}{dx}=-e^{x}-xe^{x}---equation 2.

if we add equation 1 and equation 2 we arrive at

\frac{dy}{dx}=3e^{x}-e^{x}-xe^{x}\\\frac{dy}{dx}=(3-1-x)e^{x}\\\frac{dy}{dx}=(2-x)e^{x}.
