Step-by-step explanation:
8-4=4
Answer:
x = 8
Step-by-step explanation:
Part a: <1 and <2 are alternate exterior angles because line horizontal lines are parallel
Part b: the value of x can be calculated with the following equation
7x + 15 = 10x - 9 because alternate angles has same measure
15 + 9 = 10x - 7x
24 = 3x divide both sides by 3
8 = x
Let x represent the money he originally had
x = x + 5
x - x = 5
x - x = 5
x = 5
x = 30
Answer: $30
First, your whole number has to become a fraction. Whatever whole number you get or have to use, its denominator (the bottom number of a fraction) will always be 1. Then, you multiply across. You may have to simplify.
Ex:
2/5 x 2
2/5 x 2/1
= 4/5
Question:
In a neighbourhood pet show, each of the animals entered is equally likely to win. if there are 7 dogs, 6 cats, 3 birds, and 2 gerbils entered, what is the probability that a bird will win the top prize?
Answer:
Probability that a bird will win the top prize is 0.167
Step-by-step explanation:
Given:
The number of dogs = 7
The number of cats = 6
The number of birds = 3

To Find:
Probability that a bird will win the top prize = ?
Solution:
Let us first find the total number of pets .
The Total number of pets = 7 + 6 + 3 + 2 = 18
Now the probability of a bird will win the top prize is
