Answer:
The value of m in the expression is 5
Step-by-step explanation:
Given expression as :
3 + ( 4 + 5 ) = ( 3 + 4 ) + m
Or, 3 + ( 9 ) = ( 7 ) + m
Or, 12 = 7 + m
∴ m = 12 - 7 = 5
Hence The value of m in the expression is 5 Answer
Answer:
Andre's height: y < x < 164
Step-by-step explanation:
We will first of all convert each of the statements to mathematical inequalities, before we combine them.
Let Andre's height be = x
Lin's height be = y
The maths teacher's height = 164
Andre is a little taller than Lin:
x > y
Andre is shorter than their maths teacher, who is 164 centimetres
x<164
Combining the two inequalities, we have Andre's height as
y < x < 164
This means that Lin is shorter than Andre who is in turn shorter than the Maths Teacher.
