Will odd numbers when added always make even numbers

Mathematics
1 answer:
Fittoniya [83]3 years ago

Always. consider 2x which is always even (divisible by 2)

then 2x+1 is the form of all odd numbers.

add 2 of the odd numbers together to get (2x+1)(2y+1) = (4y² +2x +2y) + 1

the part in parentheses is always even can you see why? then adding one again always gives us an odd number.

The ratio of art class to music class is 4:3. If there is 8 more students in art class, how many students are in music class
pishuonlain [190]

Answer:

9 students in music class.

Step-by-step explanation:

In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.

4 x _ = 12. —> 4 x 3 = 12.
so we need to do the same for music class.

For music there are 3.
so we multiply by 3 like we did with the 4.

3 x 3 = _ —> 3 x 3 =9.
so there are 9 students in music class.
