We must first solve the number of fiction and nonfiction books
if x is the number of fiction books and
y is the number of nonfinction books
Then,
x + y = 400
x = y + 40
Solving the system of equations:
x = 220
y = 180
Therefore, the probability that Audrey and Ryan will get both nonfiction books is
P = 180/400 + 179/399
P = 0.8986
Answer: -18, -17, -16
Step-by-step explanation:
What are consecutive integers? Consecutive integers are integers after one another without gaps.
Examples:
1, 2, 3
49, 50, 51
-22, -23, -24
They can be written as n, n + 1, n + 2, etc where n is the smallest value.
"Find three consecutive integers."
n, n + 1, n + 2
"The sum of the first and the third is -34"
(n) + (n + 2) = -34
2n + 2 = -34
2n = -36
n = -18
Answer;
-18, -17, -16
multiply 2x3xx3x4 and you get 72
so the answer would be :B
Answer:
2/12
Step-by-step explanation:
Because there are 6 tile total but he wants two put 2 numbers out of the bag twice..... you get the 12 because he pulls a number out twice and since he has 6 and then does it again it adds to 12 so the answer would be 2/12
Answer:
1:11=11:121
5:2:1=35:14:7
1.5:1.25:2.4=6:5:9.6
Step-by-step explanation:
x/11=11/121 so x equals 1
5/2=x/14 so x equals 35
1.5/x=6/5 so x equals 1.25
1.25:2.4=5/x so x equals 9.6
