2/7 + 1/3 + Unlnown side= 1/1
1/1 simply represents the whole circle. We need to find common multiples of all the numbers and change the denominator while also doing the same mathematical steps to the numerator: for example if you divide the denominator by 2 you also need to divide the numerator by 2. We end up getting 6/21 + 7/21 + Unknown/21 = 21/21
We get 13/21 + unknown = 21/21. We can solve this and get Unknown number = 8/21

1+Sin/Cos + Cos/1+Sin = 2Sec

Bond [772]

Step-by-step explanation:

Consider the left-hand side:

$\dfrac{1+\sin{\theta}}{\cos{\theta}} + \dfrac{\cos{\theta}}{1+\sin{\theta}}$

$\:\:\:\:= \dfrac{(1+\sin{\theta})^2 + \cos^2{\theta}}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:=\dfrac{1+2\sin{\theta}+\sin^2{\theta} + \cos^2{\theta}}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:=\dfrac{2+2\sin{\theta}}{\cos{\theta}(1+\sin{\theta})} =\dfrac{2(1+\sin{\theta})}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:= \dfrac{2}{\cos{\theta}} = 2\sec{\theta}$

Which value of xx makes 7+5(x-3)=227+5(x−3)=22 a true statement

kari74 [83]

Answer:

x=6

Step-by-step explanation:

The given equation is

$7+5(x-3)=22$

We need to find the value of x for which the given statement is true.

Using distributive property we get

$7+5(x)+5(-3)=22$

$7+5x-15=22$

$5x-8=22$

Add 8 on both sides.

$5x=22+8$

$5x=30$

Divide both sides by 5.

$\dfrac{5x}{5}=\dfrac{30}{5}$

$x=6$

Therefore, the given statement is true form x=6.
