Answer:

Step-by-step explanation:

no. this is not true as if you simply plug it in it would not come out as the same answer. multiplying something by 0.01 and dividing it by 100 is the game but 174.3 is 10 times larger than 17.48

Answer:

The Proof for $5^{7}+5^{6}\ is\ divisible\ by\ 6$ is below.

Step-by-step explanation:

To Prove:

$5^{7}+5^{6}\ is\ divisible\ by\ 6$

Proof:

We know law of indices

$a^{m}.a^{n}=a^{m+n}$

Therefore,

Step 1: Applying law of indices

$\dfrac{5^{7}+5^{6}}{6}=\dfrac{5^{6}.5^{1}+5^{6}}{6}$

Step 2: Taking common $5^{6}$ we get

$\dfrac{5^{7}+5^{6}}{6}=5^{6}\times (\dfrac{5^{1}+1}{6})$

Step 3: $5^{1} = 5$ so add 5 + 1 we get

$\dfrac{5^{7}+5^{6}}{6}=5^{6}\times \dfrac{6}{6}$

Step 4: Cancel 6 from both denominator and numerator we get

$\dfrac{5^{7}+5^{6}}{6}=5^{6}\times 1=5^{6}$ ...That is Divisible by 6 Proved

Answer:

The answer is 147 degrees.

Step-by-step explanation:

There are 180 degrees in a triangle. All you have to do is add the angles together that you have then subtract that from 180. 10 + 23 = 33. 180 - 33 = 147.
