Answer:
option b.)y=1/4x-7/2.....
Answer: F. is a linear relation.
Step-by-step explanation:
Answer:
The equations are:
10x + 9y = 122
x + y = 13
Step-by-step explanation:
Given Jose makes 10$ per hour washing cars and 9$ per hour walking dogs.
Also, it is given that he had worked for 13 hours total making 122$.
Let us assume the number of hours he spent on washing cars = 'x'.
Let us assume the number of hours he spent on walking dogs = 'y'.
Since, the total number of hours is 13, we can write:
x + y = 13 . . . eqn(1)
And since he has made 122$ in total, we will have:
10x + 9y = 122 . . .eqn(2)
'10x' represents the total money earned by washing cars and '9y' represents the total hours spent on walking dogs.
Hence, Eqn (1) and Eqn(2) is the answer.
Solving them will give: x = 5 and b = 8.
Answer:
Step-by-step explanation:
- Hoodies bought = x
- Shoes bought = y
- Sum = 250
- The cost difference 4 times
Let hoodies cost be k, then pit of shoes cost 4k
