Answer:
34
first of all use formula:
n(AUB)=n(A)+n(B)-n(AnB)
Answer:
They will be at a distance of 16 miles apart from each other.
Step-by-step explanation:
Both Joe and Anita start roller balding in opposite directions, and both of them have the same speed of 4 mph.
As they move oppositely in a straight line therefore, the distance between them will be the distance travelled by each of them's sum.
Distance covered by Joe in 2 hours= 8 miles
Distance covered by Anita in 2 hours= 8 miles
Therefore, the total distance from each other =16 miles
There are 7 chairs in each row length.
Step-by-step explanation:
Let number of chairs in 1 row be 'x'.
Let total number of chairs be 'y'.
Given:
Hue can form 6 rows of a given length with 3 chairs left over.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 6 plus number of chairs which is left which is 3.
Framing in equation form we get.
Also Given:
Hue can form 8 rows of that same length if she gets 11 more chairs.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 8 minus number of chairs which is required more which is 11.
Framing in equation form we get.
From equation 1 and equation 2 we can say that L.H.S is same.
So according to law of transitivity we get;
Combining like terms we get;
Using Subtraction and Addition property we get;
Now Using Division Property we will divide both side by 2.
Hence there are 7 chairs in each row length.
