1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====
multiplying by the common denominator will get rid of the fractions
Answer: 8:4:12 I believe...
Step-by-step explanation: If the order is 2-his brother 1-his friend- and 3- himself, then I believe his brother would get eight, his friend 4, and he would have twelve.
Let x be the total of students in their Junior Year.
So, 84% of x =378
84% = 0.84
0.84x=378 (divided by 0.84)
x= 450 students.
The ones that chose not to take spanish will be:
450-378=72
72 students chose not to take spanish in their junior year.
Question:
The admission fee at a carnival is $3.00 for children and $5.00 for adults. On the first day 1,500 people enter the fair and $5740 is collected. How many children and how many adults attended the carnival?
Answer:
Number of children and adults attended the carnival are 880 and 620 respectively
Step-by-step explanation:
Given:
The admission fee at a carnival for children = $3.00
The admission fee at a carnival for adults = $5.00
Number of people entered the fare on first day= 1500
Total amount collected on the first day = $5740
To Find:
Number of children and adults attended the carnival =?
Solution:
Let
The number of children be x
The number of adults be y
The we know that on the first day the total number children visited the fare was 1500
x + y = 1500
x = 1500 - y------------------------------(1)
Also the total fare collected was $5740
x(3) + y(5) = 5740
3x + 5y = 5740-------------------(2)
Substituting (1) in (2),
3 (1500 - y) + 5y = 5740
4500 -3y + 5y = 5740
-3y + 5y = 5740 - 4500
2y = 1240
y = 620 adults
From 1 ,
x = 1500 - 620
x =880
Answer:
25 students
Step-by-step explanation:
Let t= total students
Take the total number of students and multiply by the percent that are boys to get the number of boys
t * 40% = 10
Change to decimal form
t*.40 = 10
Divide by .4 on each side
.40t /.4 = 10/.4
t =25
There are 25 students
