Answer:
A = 744 meters B = 489 meters
Step-by-step explanation:
A = B + 255
2B - A = 234
-2B -2B Subract the -2B from both sides
-A = -2B + 234
A = 2B - 234 Divide by -1 to get A alone
B + 255 = 2B - 234 Set both equations equal to each other
- B -B
255 = B - 234
+234 +234
489 = B
Plug 234 in for B in the original equations
A = 489 + 255
A = 744
Answer:
11 tickets
Step-by-step explanation:
1. write an equation:
First, variable x symbolizes the number of adults who bought tickets. And variable y symbolizes the number of students.
If each adult paid $6, and each student paid $4, and the total dollars you've collected is 104, this is how we'll write our equation:
6x + 4y = 104
2. we can write another equation based on this information: "You sold 21 tickets". Which concludes that the number of tickets adults and students had paid for equals the number of tickets you've sold:
x + y = 21
3. now, we've got two equations. Let's compensate:
x + y = 21
x = 21 - y
6x + 4y = 104
6 (21 - y) + 4y = 104
126 - 6y + 4y = 104
-6y + 4y = -22
-2y = -22
y = -22 / -2
<u>y = 11</u>
So the number of student tickets is <u>11</u>.
Before you start the job, gather up your tools.
You need three tools for this job. Let's make sure
you remember how to use them:
#1). 3 is the same thing as 3/1
#2). When you need to divide fractions, turn the
second one upside down, and then multiply them.
#3). When you're multiplying fractions, multiply the numerators
to get the numerator of the answer, and multiply the denominators
to get the denominator of the answer.
Those are the tools you need to solve this problem.
1). 3/4 divided by 3 is the same as 3/4 divided by 3/1 .
2). To divide by 3/1, multiply by 1/3 .
Now you have 3/4 times 1/3 .
3). That's the same as (3 x 1) / (4 x 3) = 3/12 =<em> 1/4</em>
