The number is 28.
The equation would be:
237 + 6(x) = 405
The problem states that 6 times the opposite of a number, however, since the number sign was not given, we do not know whether it is in a positive or negative form. So we leave it as only x.
237 + 6x = 405
6x = 405 - 237
6x = 168
6x / 6 = 168 / 6
x = 28
To check:
237 + 6 (28) = 405
237 + 168 = 405
405 = 405
Answer:
10/7 is a simple fraction, and √2 cannot be written as a simple fraction. So, they are not the same.
Step-by-step explanation:
10/7 is a number that has a numerator and a denominator.
Suppose √2 = 10/7, then √2 can also be written as a number that has a numerator and a denominator.
Since this is not the case, 10/7 cannot be the same as √2.
We are given expression: 
.
Tyna simplified the given expression to 
.
Explanation: In order to simplify , Tyna need to simplify rational expression 
.
On dividing top and bottom by 3, we get 
.
Which Tyna got correct.
Now she need to simplify 
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be 
.
<h3>So, the final answer should be
.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
