5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
Answer:
C. Because (-3)^2 is NOT equal to -9
Step-by-step explanation:
Let x be the number of people at University B
x + (x+3.5) = 9.5
2x +3.5 = 9.5
2x = 6
x = 3 million students at University B
x + 3.5 = 3 + 3.5 = 6.5 million students at University A
Simplify 1/9 y to y/9
y/9 = -2
then multiply 9 by both sides
y = -2 x 9
then simplify
y = -18
