Well, I Don't See The Answer Choices, But The Next Step Is Most Likely To Subtract 8 From Both Sides.
Answer:
The answer is complementary ⇒ last answer
Step-by-step explanation:
In any right triangle there are two acute angles sum of them is 90°
∵ The two angles will be complementary if there sum is 90°
∵ cosФ = sinβ
∵ cosФ = sin(90 - Ф)
∴ β = 90 - Ф
∴ β + Ф = 90
∴ β and Ф are complementary
Lets say each jersey cost x,
then 12 jerseys will cost 12x
Total costs will then be 12x + 3, 12x of costs plus $3 of shipping
We already know that the total cost is $99
so 12x + 3 = 99
Now isolate x by subtracting 3 from both sides
12x 3 - 3 = 99 - 3
12x = 96
Now divide both sides by 12 to find x
12/12x = 96/12
x = 8
Each jersey cost $8
Answer: You can use the equation 12x + 3 = 99 to find the cost of each jersey
