7x-29-21x=3-(12+2x)
-14x-29=3-12-2x
-14x-29=-9-2x
-12x-29=-9
-12x=20
x=-20/12
x=-5/3
Final answer: x= -5/3
The <em>correct answer</em> is:
7/29 = 0.24.
Explanation:
We can construct a two-way table from this information.
There are 40 total students. 10 of them are athletes; this means 40-10 = 30 are not athletes.
3 of the athletes are honors students. There are 10 athletes; this means there are 10-3 = 7 athletes that are not honors students.
There are 11 honors students. This means that there are 40-11 = 29 students that are not honors students.
For this probability, we only consider the number of athletes that are not honors students (7) and the total number of students that are not honors students (29). This makes the probability 7/29 = 0.24.
First, lets convert the 1/8 of a mile into decimal form. To convert 1/8 to a decimal, divide the denominator into the numerator. 1 divided by 8 = . 125.
For the first 0.125 miles, its $1.75. So remove that from the ride cost and keep track of the 0.125 miles elsewhere.
$7.75 - $1.75 = $6
Miles: 0.125
We’re left with $6. Let’s divide the $6 by $0.30 to figure out how many miles the $6 will buy us.
6 / 0.30 = 20
So 0.30 goes into 6 twenty times.
So our answer will be the sum of 20 and 0.125.
20 + 0.125 = 20.125 Miles
Answer: $7.75 will buy you a 20.125 mile ride.
Answer:
About 936 are girls
Step-by-step explanation:
Take the fraction 3/7, since that is the remaining proportion of students that are girls, and multiply it by 2184.
