Answer:
100>=500-15x
Step-by-step explanation:
He needs at least 100, so it's greater than OR equal to 100. He starts with 500 and goes down 15 each week. The x stands for the amount of weeks that are in the school year. Sorry for the terrible formatting on the greater than or equal to.
216. All you have to do to find volume is to multiply the numbers. 12 x 18 = 216.
(-1/8 c+16)-(3/8+3c)=
= -1/8c + 16 - 3/8 - 3c
= (-1/8 c - 3c) + (16 - 3/8)
= (1/8 c - 24/8 c) + (128/8 - 3/8)
= - 23/8 c + 125/8
