Answer:

12

Step-by-step explanation:

assuming you wish to evaluate the expression.

substitute x = 5 into the expression

\frac{2(5+13)}{3}

= \frac{2(18)}{3}

= \frac{36}{3}

= 12

You have to use the distributive property, therefore you get 2x+13/3.

The next step is to do 2 x 5 because they gave us a number for the variable x. Then you have to do 2 x 13 which gives us 26.

10+26=36 and 36/3=12, hope I helped, Have a nice day! :)

Find the number to which the sequence {(3n+1)/(2n-1)} converges and prove that your answer is correct using the epsilon-N defini
Nat2105 [25]
By inspection, it's clear that the sequence must converge to \dfrac32 because

\dfrac{3n+1}{2n-1}=\dfrac{3+\frac1n}{2-\frac1n}\approx\dfrac32

when n is arbitrarily large.

Now, for the limit as n\to\infty to be equal to \dfrac32 is to say that for any \varepsilon>0, there exists some N such that whenever n>N, it follows that

\left|\dfrac{3n+1}{2n-1}-\dfrac32\right|

From this inequality, we get

\left|\dfrac{3n+1}{2n-1}-\dfrac32\right|=\left|\dfrac{(6n+2)-(6n-3)}{2(2n-1)}\right|=\dfrac52\dfrac1{|2n-1|}
\implies|2n-1|>\dfrac5{2\varepsilon}
\implies2n-1\dfrac5{2\varepsilon}
\implies n\dfrac12+\dfrac5{4\varepsilon}

As we're considering n\to\infty, we can omit the first inequality.

We can then see that choosing N=\left\lceil\dfrac12+\dfrac5{4\varepsilon}\right\rceil will guarantee the condition for the limit to exist. We take the ceiling (least integer larger than the given bound) just so that N\in\mathbb N.

Find the value of x.
koban [17]

Answer:

x = 110°

Step-by-step explanation:

The Outside Angle Theorem states that the measure of the angle formed by two secants or a secant and tangent from a point outside of a circle is half the difference between the two arcs.

This means that ½ (210 – x) = 50.

½ ( 210 – x ) × 2 = 50 × 2

210 – x = 100.

210 – x + x = 100 + x.

210 = 100 + x.

100 + x = 210.

100 + x – 100 = 210 – 100.

x = 110.

This value must be true because:

½ ( 210 – 110 ) = 50.

½ ( 100 ) = 50.

50 = 50.

1 7/8 divided by 2 8/11
Bingel [31]

Answer: 11/16

<u>Turn 1 7/8 into an Improper Fraction</u>

Multiply 1×8 and get 8. Now add 7 and get 15.

1 7/8 = 15/8

<u>Turn 2 8/11 into an Improper Fraction</u>

Multiply 2×11 and get 22. Now add 8 and get 30.

2 8/11 = 30/11

<u>Do Keep Change Flip</u>

Keep: 15/8

Change ÷ into ×

Flip: 30/11 into 11/30

Your New Problem: 15/8×11/30

<u>Multiply</u>

15/8×11/30=165/240

<u>Simplify</u>

165/240÷15/15=11/16
