Substitute in (2)
Answer: y+x
Step-by-step explanation: The commutative property is like no matter how much you switch the numbers around you gonna get the same answer
Answer: Divide distance by speed to get time.
Speed and time are inversely proportional. As speed increases, time decreases.
Distance = speed × time So distance is the the constant of variation.
Step-by-step explanation: Divide distance by speed to get time.
180km÷50km/h = 3.6h by Car
180km÷45km/h = 4h by Bus
180km÷40km/h = 4.5h by Truck
180km÷25km/h = 7,2h by Bicycle

<u>Evaluating Algebraic Expressions</u>
Given an expression where variables (letters) are included, evaluate the expression at specific values of the variables means to substitute the values into the expression, operate, and give the final result.
The expression provided in the question is:
4m + 3
Evaluate at m=5
Substitute m for 5 recalling 4m really means 4*m, a product:
4*5 + 3 = 20 + 3 =23
