Answer:
<em>15 students visited both museums.</em>
Step-by-step explanation:
<u>Operations With Sets</u>
Sets are a collection of elements. Some sets have elements in common with other sets. These elements are said to be in their intersection. If we know the number of elements in the set A and in the set B, and also the total number of elements in both sets, we can say
where is the total number of elements, N(A) and N(B) are the number of elements in A and B respectively, and is the number of elements in their intersection. If we wanted to know that last number, then we isolate it
Let A= Students who visited the museum of natural history
B=Students who visited the natural air and space museum
We know
Answer: 15 students visited both museums.
Note: We are assuming no students didn't visit at least one museum
First set both equations equal to y
y = -1/2x + 3
y = 3x - 4
Then set these two equal because they both equal y
-1/2x + 3 = 3x + 4
Combine like terms and solve
7 = 3.5x
x = 2
y also = 2 when you plug it back in
Therefore, (2,2)
Answer:
Faisal receives $241
Ahmed receives $482
Walid receives $723
Step-by-step explanation:
I am going to build a system of equations to solve this question.
We have that:
x is the amount that Faysal received.
y is the amount that Ahmed received.
z is the amount that Walid received.
Ahmed, Walid and Faisal made $1446 profit from selling used books.
This means that
Ahmed to receive double amount of Faisal
This means that
Walid to receive triple amount of Faisal.
This means that
So
Faisal receives $241
Ahmed receives $482
Walid receives $723
Answer:
Speed = 16 km per hour
Speed = meter per second
Step-by-step explanation:
b). Total distance covered to and fro = 12 + 12
= 24 km
Total time taken to cover this distance = 1.5 hours
Since, speed =
=
= 16 km per hour
Since, 1 km = 1000 m
And 1 hour = 3600 seconds
16 = 16 × meter per second
=
=
= meter per second
