Mr. and mrs. O'hara have twice as many boys as girls. They have two girls. How many children do they have?

6 children

Step-by-step explanation:

If the O'hara's have 2 girl and we know that they have twice as many boys then the equation would look like this..

2 x 2 = boys

There are 4 boys

But they are asking total children which will include the girls,

4 + 2 = 6 children

Hope this helps :)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
