D= difference in height
A= Alex's height (1.6m) N= Noah's height (1.5A)
Step 1:
D=N-A
substitute N= 1.5 A in for N
D= 1.5(1.6) - 1.6
D= 2.4 - 1.6
D= 0.8 m difference in height
Step 2:
Convert meters to centimeters 1 m = 100 centimeters
0.8 x 100-80cm
Noah is 80cm taller than Alex.
Hope this helps! :)

False.
Here is a counterexample.
3/4= 0.75
3 and 4 are both integers but the quotient is 0.75 which is not an integer. 0.75 is a rational number.
Step-by-step explanation:
∠4 = ∠1 & ∠2 = ∠3
360 - 2(98) = ∠2 + ∠3
∠3 = 164/2
∠3 = 82°
Answer: -6 -2
