The sum of two consecutive integers is 81. Determine the lesser of the two numbers.
Answers
Given that,
the two numbers are consecutive
The two numbers are
x and x + 1
Sum of the numbers = 81
x + (x + 1) = 81
x + x + 1 = 81
2x = 81 - 1
2x = 80
x = 80/2
x = 40
Therefore, the two numbers are x = 40 and x + 1 = 41

x + y + z = 180°
x + 50° + 65° = 180°
x + 115° = 180°
x = 65°

A bag contains 40 red and green marbles. The ratio of red marbles to
green marbles is 3 to 1. How many green marbles are in the bag?
A. 10
B. 15
C. 20
D. 30
Answers
Answer:
39/40
Step-by-step explanation:
Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.
However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)

Step-by-step explanation:
The formula to find slope from two points is (x₂ - x₁) / (y₂ - y₁).
Substituting the points in (2, 4 = x₁, y₁ and 5, -8 = x₂, y₂) we get (5 - 2) / (-8 - 4).
= 3 / -12
= - 1/4
