Answer:

w=2

Step-by-step explanation:

3 + 4(w + 5) = 31

distribute 4(w + 5)

4 x w = 4w

4 x 5 = 20

rewrite your equation

3 + 4w + 20 = 31

add like terms

3 + 20 = 23

rewrite equation

4w + 23 = 31

subract 23 on both sides

4w + 23 = 31

-23 -23

4w = 8

divide by 4 on both sides to get w by itself

4w = 8

4      4

w = 2

Answer:

<h2>8/4</h2>

We have,

3+4(w+5)

=31 Or, 3+20+4w

=31 or, 4w

=31−23

w=8/4

Thus, w comes out to be 2 .

Rewrite and Order 6/7 and 9/11
Aleksandr-060686 [28]

Answer:

6/7 = 66/77

9/11 = 63/77

6/7 is greater than 9/11

Step-by-step explanation:

To give fractions a common denominator you must find the LCM(lowest common multiple) of this two denominators.

So, we have 7 and 11. You must find a multiple 7 and 11 share. This means that the number must be divisible by 7 and 11. The LCM for 7 and 11 is 77.

Now we make both the denominators 77.

Now look at the numerators. Look at 6/7. We multipled 7 by 11 to get 77. Therefore, we must also multiply 6 by 11.

Now we have, 66/77

Do the same with the other fraction but other way around:

11 x 7 so

9 x 7 = 63

So,

63/77

So 6/7 is now 66/77 and 9/11 is now 63/77

Now compare:

66 > 63

66 is bigger so 6/7 is greater.

6/7 is greater than 9/11

dexar [7]

Answer:

791.2 ft

Step-by-step explanation:

The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.

H=\sqrt {x^{2}+y^{2}}

where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then

H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft
