Answer:
1. y = 30x
2. y = x+5
3. y = 2x
4. y = x+2
Step-by-step explanation:
1. The speed of a car is x miles per hour. The total distance the car covers is 30 minutes is y
Total Distance = y
Time = 30 minutes
Speed = x
So, equation will be y =30x
2. Tina's age y is 5 years more than her brother Tim's age x.
Tim's age = x
Tina's age y= x+5
So, y = x+5
3. The cost to produce a table y is two times the cost to produce a chair,x
Cost of chair = x
Cost of table = y = 2x
So, y = 2x
4. The time required to bake a chocolate muffin, y is 2 minutes more than the time required to bake a vanilla muffin x
Time to bake vanilla muffin = x
Time to bake chocolate muffin= y= x+2
so, y = x+2
