Question # 14
Given the numbers
10 11 12 13 14 15 16 17 18 19 20
Let 'x' be the number
The condition breakdown:
I am less than 20.
- So the number 'x' must be less than 20 i.e. x < 20
I am more than 13.
- So the number 'x' must be greater than 13 i.e. x > 13
I am less than 17.
- So the number 'x' must be less than 17 i.e. x < 17
Finally:
I am 4 more than 12
i.e. 12+4 = 16
Thus, the number is x = 16
Question # 15
Part a)
Given the numbers
10 11 12 13 14 15 16 17 18 19 20
Let 'x' be the number
The condition breakdown:
I am more than 10.
I am less than 20.
I am more than 12.
I am less than 15.
As the numbers left after all the conditions are fulfilled are 13 and 14.
- But the last condition is, of the numbers that left, the number is greater than all the remaining numbers.
So, from the remaining number 13 and 14;
14 > 13
Thus, the number x = 14
Part b)

Answer:
The Large Box Weighs 18 kg, and the small box weighs 6.5 kg
Step-by-step explanation:
Let a= the weight in kg of a large box
Let b= the weight in kg of a small box
Multiply both sides of (1) by 4 and subtract (2) from (1)
1. 20a+8b=412
2. -3a-8b= -106
17a=306
a=18
and
5*8+2b=103
90+2b=103
2b=13
b=6.5

The answer to the question
Answer:
All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.
Step-by-step explanation:
The old math saying: "Every square is a rectangle, but not all rectangles are squares."
What makes a rectangle a rectangle is that it has four right angles.
A square also has four right angles. Therefore, a square is a type of rectangle.
<h3>What makes the other answers wrong:</h3>
A rectangle does not have equal lengths on all four sides like a square does.
A square MUST have four right angles for it to be a square.
