If the cost is per shirt it would be 1.50 plus 4.50 making it 6.
If the sin 90° = 1, the cos 0° = 1.
That is because sine and cosine of the complement angles are equal.
Hope tthis helps :)s
To cross out a variable (in this case, x) we can add both equations together to get -5y=10. Dividing both sides by -5, we get y=-2. Next, plugging it into -3y+5x=26, we get 6+5x=26. Subtracting 6 from both sides, we get 5x=20. Next, we can divide both sides by 5 to get x=4
Answer:
2-3 -7-4 is the answer I hope it helps
I think it is 18 because how I do it, 60 / 10=
6x3=18 I divide it into tenths and then I muliply by how much.
