Mother hung the clothes that have been washed. There were 27 different coloured T-shirts and school uniforms that were washed. Mark wore a set of white polo shirt and plain white undershirt.on each school day for 5 days. Anna wore a pair of blouse and skirt on each school day for 5 days. Three of each kind of clothes quickly dried under the sun and were removed from the clothesline. How many shirts are still on the clothesline? Write the mathematical expression that represents the number of shirts that still hang on the clothesline and solve the expression.
Oh, it sounds like the clothesline has turned into quite the fashion show! Let's see if we can figure out how many shirts are still hanging there.
We know that there were 27 different colored T-shirts and school uniforms in total. Mark wore a set of white polo shirt and plain white undershirt for 5 days, and Anna wore a pair of blouse and skirt for 5 days as well.
So in total, there were 5 sets of Mark's shirts (1 white polo shirt + 1 plain white undershirt) and 5 sets of Anna's shirts (1 blouse + 1 skirt), which give us a total of 10 shirts worn by Mark and Anna each day.
Now, three of each kind of clothes quickly dried and were removed from the clothesline. For Mark, this means 3 sets of shirts (with a polo shirt and undershirt) were taken off, and for Anna, this means 3 sets of clothes (with a blouse and skirt) were also removed.
To find out how many shirts are still on the clothesline, we need to subtract the shirts that were taken off from the total number of shirts.
The expression that represents the number of shirts still hanging is:
27 - (3 + 3)
And when we solve this expression, we get:
27 - 6 = 21
So, there are still 21 shirts hanging on the clothesline. Looks like there's still a lot of fashion to enjoy!
To find the number of shirts that still hang on the clothesline, we need to calculate the total number of shirts that were initially hung and subtract the shirts that have been removed.
Let's break down the given information:
- There were 27 different colored T-shirts and school uniforms.
- Mark wore a set of white polo shirt and plain white undershirt on each school day for 5 days. So, Mark wore 5 sets of shirts.
- Anna wore a pair of blouse and skirt on each school day for 5 days. So, Anna wore 5 sets of shirts.
- Three of each kind of clothes quickly dried under the sun and were removed from the clothesline.
Now let's calculate the number of shirts that still hang on the clothesline:
Initial number of shirts = 27
Number of shirts worn by Mark = 5 (sets of shirts)
Number of shirts worn by Anna = 5 (sets of shirts)
Number of shirts removed from the clothesline = 3 (each kind)
Total number of shirts worn = (Number of shirts worn by Mark) + (Number of shirts worn by Anna) = 5 + 5 = 10
Total number of shirts removed = (Number of shirts removed from the clothesline) * 2 (because there are 2 shirts in each set) = 3 * 2 = 6
Number of shirts still on the clothesline = Initial number of shirts - Total number of shirts worn - Total number of shirts removed
Number of shirts still on the clothesline = 27 - 10 - 6 = 11
So, there are 11 shirts still on the clothesline.
Mathematical expression: 27 - (5 + 5) - (3 * 2) = 11
To find the number of shirts that still hang on the clothesline, we need to subtract the number of shirts that have been removed from the total number of shirts washed.
Let's break down the given information:
- Initially, there were 27 different-colored T-shirts and school uniforms that were washed.
- Mark wore a set of white polo shirt and plain white undershirt for 5 days, which means he used 1 set per day.
- Anna wore a pair of blouse and skirt for 5 days, which means she used 1 pair per day.
- Three of each kind of clothes quickly dried under the sun and were removed from the clothesline.
To calculate the number of shirts still on the clothesline, we need to subtract the number of shirts that have been removed from the total number of shirts washed.
Let's calculate each type of clothing separately:
Mark's shirts:
Mark wore 1 set of clothes (1 shirt + 1 undershirt) per day for 5 school days. So the total number of Mark's shirts used is:
1 set/day * 5 days = 5 sets.
Anna's shirts:
Anna wore 1 pair of clothes (1 blouse + 1 skirt) per day for 5 school days. So the total number of Anna's shirts used is:
1 pair/day * 5 days = 5 pairs.
Now let's calculate the remaining shirts on the clothesline:
Total shirts used = Mark's shirts + Anna's shirts
Total shirts used = 5 sets + 5 pairs
To compare the number of sets and pairs, we need to convert one of them to the other type. Since there are 3 sets and 3 pairs that were removed from the clothesline, we can convert either sets to pairs or pairs to sets by dividing by 3.
Let's convert sets to pairs:
Total shirts used = (5 sets * 3 pairs/set) + 5 pairs
Total shirts used = 15 pairs + 5 pairs
Total shirts used = 20 pairs
Now, we subtract the total number of shirts used from the initial total:
Shirts still on the clothesline = Total shirts washed - Total shirts used
Shirts still on the clothesline = 27 shirts - 20 pairs
Note: Since we want the answer in terms of shirts, we should convert the pairs back to shirts.
1 pair = 1 blouse + 1 skirt = 2 shirts
Shirts still on the clothesline = 27 shirts - (20 pairs * 2 shirts/pair)
Shirts still on the clothesline = 27 shirts - 40 shirts
Shirts still on the clothesline = -13 shirts (This answer doesn't make sense because it's negative, which implies that more shirts were used than available).
It seems that there might be an error or missing information in the given problem, as we cannot have a negative number of shirts remaining on the clothesline with the provided information.
