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:
1414 cm³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
For a radius of 5 cm and a height of 8 cm, the volume is ...
V = π(5 cm)²(18 cm) = 450π cm³ ≈ 1414 cm³
The volume of Nadia's sugar container is about 1414 cm³.
_____
<em>Additional comment</em>
The value will be 1413 cm³ if you use 3.14 for π.
The area of the enlarged picture on the wall is gotten as; D: 486 in²

The formula for Linear scale factor is;
L.S = Image distance/object distance
Thus, from the attached image, we can find the Linear scale factor as;
L.S = OL'/OL
L.S = 54/ 12
L.S = 9/2
Area scale factor is equal to the square of linear scale factor. Thus;
Area scale factor = (9/2)²
Area scale factor = 81/4
Now,
81/4 = Area of larger rectangle/Area of smaller rectangle
Area of the smaller rectangle = 4 ×6 = 24 in²
Thus;
Area of enlarged picture on wall = (81/4) × 24
Area of enlarged picture on wall = 486 in²
