Answer:
The number of girls in Mr Brown's Class were:
7
Step-by-step explanation:
Let the number of girls in Mr. Browns Class be 'x'
Then the number of girls in Mrs Pitt's Class are: x+4
( Since,it is given that:
there are 4 more girls in Mrs Pitt's class than Mr browns class )
Now, five girls moved from Mrs Pitt's class to Mr browns class.
This means that now,
The number of girls in Mr Browns class are: x+5
and Number of girls in Mrs Pitts class are: x-1
( Since, x+4-5=x-1)
Now, as we are given that:
There are twice as many girls in Mr browns class as there are in Mrs Pitt's this means that:
x+5=2(x-1)
x+5=2x-2
2x-x=5+2
x=7
Hence, the number of girls in Mr Brown's Class were:
7 girls.
Which of the following relations has a domain of {-2, 0, 5}? Choose all that apply. {(-2, 5), (3, 4), (5, 1)} {(-2, 3), (0, 1),
8090 [49]
Answer:
Second option: {}
Third option: {}
Step-by-step explanation:
By definition, the Domain of a relation is the set of all the x-coordinates of the ordered pairs (It is necessary to remember that the x-coordinate is the first element of the ordered pair).
Then, we know that the set of all the x-coordinates of the relation we need to find is: {}
First option {}:
Domain: {}
Second option {}:
Domain: {} (Notice that we do not need to write -2 twice)
Third option {}:
Domain: {}
Fourth option {}:
Domain: {}
The relations {} and {} has a Domain of {}
