280 adults were there in the train.
What is linear equation definition and example?
- The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
- An example of linear equation is y=mx + b. noun. 20.
- A polynomial equation of the first degree (such as x = 2y - 7)
Given,
Total children are in the train = 40
1/8 are children in train and no of children in train ,
∴ 1/8 × x = 40
x = 40 × 8 ⇒ 320
The no of passenger in train = 320
in total passenger, 40 are children .
So, rest adults passengers are = 320 - 40 ⇒ 280
There fore, 280 adults were there in the train.

Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1
_____
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
_____
Of course, it can be useful to understand how moving the decimal point changes the exponent:
9 = 0.9×10 = 0.9×10^1
Answer:
Step-by-step explanation:
This number is real, negative and rational.
Answer:
The correct answer is option B.
Step-by-step explanation:
The given rational expression is:
Factor the numerator and the denominator:
Factor the numerator using difference of two squares and the denominator using factorization by grouping.
This function is defined if and only if the denominator is not zero.
That is: (x+3)(x+2)≠0.
x≠-2,x≠-3
We simplify now to obtain:
The correct choice is the second option.
