The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2
Hope this helps :)
X + y = 27
x = y + 3
y + 3 + y = 27
2y + 3 = 27
2y = 27 - 3
2y = 24
y = 24/2
y = 12
x = y + 3
x = 12 + 3
x = 15
ur numbers are 12 and 15
A = 5/6(B + C)
multiply 6 on both sides
6A = 5(B + C)
divide 5 from both sides
6A/5 = B + C
subtract B from both sides
6A/5 - B = C
Answer:
10) 9*9*9*9 = 6561
11) 2*2*2 = 8
12) 3*3*3*3*3 = 243
13) 4*4*4 = 64
14) 6*6*6*6*6 = 7776
15) 5*5*5*5 = 625
16) 8.5*8.5*8.5 = 614.125
17) 1.3*1.3 = 1.69

Answer:
a) 62
b) 31/45
Step-by-step explanation:
a) The table tells you there are 42 males, and 20 more females that study biology.
42 +20 = 62 . . . are male or study biology or both
__
b) Of the total of 90 people, 62 are male or study biology (or both). The probability that any person is in that category is ...
62/90 = 31/45 = P(male or biology)
