Answer:
45 points
Step-by-step explanation:
You could do it with proportions. Start with 18/x=40/100. then, cross multiply and you should get x=45.
Twice a number decreased by 11 is -23
Let the number be x
So we get the equation
2x -11 = -23
Add 11 to both sides
2x = -12
Divide both sides by 2
x = -6
So the number is -6
Negative 6

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.
