Answer:
Jersey cost $8 and pair of shorts $5
Step-by-step explanation:
There are several ways to solve this, but I will find the solution using the system of equations.
Let's mark price of jersey with x, and price of pair of shorts with y. That means:
12x + 12y = 156
4x + 6y = 62
Now, we can multiply the second equation with -2 to cancel out y:
12x + 12y = 156
-8x - 12y = -124
That only leaves us with:
12x - 8x = 156 - 124
4x = 32
x = $8
Now we plug the value for x into any equation to find y:
4x + 6y = 62
32 + 6y = 62
6y = 30
y = $5
Answer:
4
Step-by-step explanation:
the absolute value makes everything positive
Answer:
D
Step-by-step explanation:
h(x) = 6x + 1
y = 6x + 1
switch x and y
x = 6y + 1
solve for y
6y = x - 1
y = (x-1) / 6
