How to solve 3x/7 - 1/2 = 1/14

Answer: 4/3

Step-by-step explanation:

First off, we should all get the denominators to be the same.

14 is the LCM of each of the denominators, so:

3x / 7 times 2/2 = 6x/14

-1/2 times 7/7 = -7/14

and 1/14 is 1/14

So now we have

6x/7 + -7/14 = 1/14

We can multiply everything by 14 to get rid of the denominator completely, which leaves us with:

6x - 7 = 1

Then we just solve like a normal equation:

6x = 8

x = 8/6 , or 4/3

Find the value of x. A. 53–√ in B. 241−−√ in C. 55–√ in D. 9

castortr0y [4]

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

${a}^{2} = {b}^{2} + {c}^{2}$

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

${10}^{2} = {5}^{2} + {x}^{2}$

${x}^{2} = {10}^{2} - {5}^{2}$

${x}^{2} = 100 - 25$

${x}^{2} = 75$

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you

Find a5, when a1 =4, r=5

sasho [114]

Answer:

Answer: a5 = 2500

Step-by-step explanation:

For a geometric sequence:

First term = a0

Second term = a1 = a0*r

Third term = a2 = a0*r^2

Fourth term = a3 = a0*r^3

....

nth term = a(n-1) = a0*r^(n-1)

Given: a1 = 4 = a0*r

Also: r = 5

So, a0*5 = 4 => a0 = (4/5)

a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500

Hope this helps
