Answer:
101
Step-by-step explanation:
31+20+25+25=101
35 students would not know any of the three languages, because if 30 know French, 19 knew German, and 16 knew Russian, that must mean that 65 students know at least one of the three languages. So you subtract 65 from 100 and end up with 35
Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)
Answer:
you need to solve for x
Step-by-step explanation:
the ez way for me is by flipping it so now it is -(7-10)=x and 10 -7=3
