15=pants
d less than pants means
15-d
5 of them
5(15-d)=cost of shirts
so total cost=15+5(15-d)
Answer:
x = 50°
Step-by-step explanation:
180° - 80° = 100°
100° ÷ 2 = 50°
50° + 50° + 80° = 180°
Answer:
You can put this solution on YOUR website! 5X - 20 = 10 * X 5X - 20 = 10X Subtract 5x from each side-20 = 5X Divide each side by 5-4 = X. Let's make sure it works... 20 less than five times a number (-20-20) is equal to the product of ten and that number (10 * -4)
Step-by-step explanation:
I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.
Answer:
<h3>-cos10°</h3>
Step-by-step explanation:
cos is positive at first and fourth quadrant
so, cos (-x) = cos (x)
also, cos(180-x) = -cos x
cos (180+x) = -cos x
cos (-170°) = cos (170°)
cos(170°) = cos (180° - 10°)
= - cos 10°
