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.
I believe the only complex number that has the absolute value of 5 is

Answer:
906 inches³
Step-by-step explanation:
The volume of a triangular pyramid = 1/3 (area of base) × h
area of the base = 1/2 × 19 × 13 = 123.5 inches²
v = 1/3 × 123.5 × 22 = 905.666... ≈ 906 inches³
The volume of the triangular pyramid is 906 inches³
Hope this helps!
