Question

8/5 +30/7 solve these problem step by step explanation​

Answer 1

ANSWER

$\bf\red{ \huge \frac{206}{35} }$

Step-by-step explanation:

$\bf\red{ \frac{8}{5} + \frac{30}{7} } \\ \\ \bf\red{ \implies \: \frac{56 + 150}{35} } \\ \\ \bf\red{ \implies \frac{206}{35} }$

Answer 2

Step-by-step explanation:

$If, 8=56, 7=42, 6=30, 5=20, what \: is \: 3=x?$

The pattern, as almost everyone here pointed out, is obvious.

I am a bit concerned that this began as nonsense and then ended up being validated by all the other “correct answers”.

To put it simply, 8 is not equal to 56 and 7 is not equal to 42 and 6 is not equal to 30 and 5 is not equal to 20. If you think otherwise, then I will give you $8 and you give me back $56 and we will call it even.

In mathematics, symbols are important. Some symbols are allowed to do double duty; but they don’t do so arbitrarily.

The

$8 => 56, 7 => 42, 6 => 30, 5 => 20. If 3 => x$

simplest way to state what you seem to wish to convey would be:

If there is one symbol central to the core of mathematics, it is probably the equal sign. Give it the value it is worth; and don’t tamper with its proper usages.
