Answer:
18
Step-by-step explanation:
3x + 2x = 90
5x = 90
5x/5 = 90/5
x = 18
You want to divide the cost of the books by the total costs.
308/2800 = 0.11
You then need to convert 0.11 to a percent: 0.11 = 11%
Therefore, 11% of her costs last semester were spent on books.
That’s too much!
8x-10=3x+90. 8x-3x=90-10. 5x=80. x=16. So angle B is 3*16+90=138° :)
