Each pair of pants cost $27. Set up a system of equations.
5t + 5p = 220
5t + p = 112
Subtracting the second equation from the first,
4p = 108
p =27
Answer:
x=1
Step-by-step explanation:
3/2+1/2x=2x
Multiply each side by 2 to get rid of the fractions
2(3/2+1/2x)=2x*2
3+x = 4x
Subtract x from each side
3+x-x = 4x-x
3 = 3x
Divide each side by 3
3/3 = 3x/3
1 =x
Given:
Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.
She has a total of 32 marbles.
To find:
The number of red marbles.
Solution:
Let number of blue marbles be x.
Then, number of red marbles = 2x
Number of yellow marbles = 8
Total number of marbles = 32




Now,
Number of red marbles 
Therefore, there are 16 red marbles.
Answer:
<u>Cost in US$ = 12 - 16 - 24 - 36 - 40</u>
<u>Number of tickets = 3 - 4 - 6 - 9 - 10</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
For a high school basketball game, it cost's US$ 12 for every 3 tickets.
It means that every ticket costs US$ 4 (12/3 = 4)
2. Let's complete the table below
<u>Cost in US$ = 12 - 16 - 24 - 36 - 40</u>
<u>Number of tickets = 3 - 4 - 6 - 9 - 10</u>
For US$ 16 = 4 * 4
For US$ 24 = 6 * 4
For US$ 36 = 9 * 4
For US$ 40 = 10 * 4
