For the given statements we need to match the given equations.
What is an equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Statement 1: An adults and 5 children rent skates. It costs $4 per adult for stakes and a total of $16.
Let the cost of 5 children rent skates be 5x.
Now, 4+5x=16
Statement 2: It costs Mikael $4 to make a bike bag, and he sells each for $5. He has made a profit of $16 so far.
Profit=Selling Price-Cost Price
⇒Profit=5-4
⇒(5-4)x=16
Statement 3: It was 16° C. It began falling 4° C per hour until it reached 5° C.
It began falling 4° C per hour, which can be written as 4x.
Now, 16-4x=5
Therefore, the equation for Statement 1 is 4+5x=16, the equation for Statement 2 is (5-4)x=16 and the equation for Statement 3 is 16-4x=5.
