Answer:
The speed of a car is x miles per hour.
The total distance the car travels in
30 minutes is y. ....>>> y = 0.5x
The cost to produce a table, y, is two
times the cost to produce a chair, x. ..> y = 2x
The time required to bake a chocolate
muffin, y, is 2 minutes more than the
time required to bake a vanilla muffin, x.....>> y = x + 2
Tina’s age, y, is 5 years more than
her brother Tim’s age, x. .......>> y = x + 5
Step-by-step explanation: The only really tricky one is the "speed of the car ..." because the speed is given in miles per hour and the time is given in minutes so that is 0.5 hour times time
Otherwise, "times" means multiplication and "more than" means addition.
