Answer:
6 minutes 8 balloon animals. 45 minutes 60 balloon animals!
Step-by-step explanation:
I divided 15 by 6 and got 2.5, so I then divided 20 by 2.5 and got 8 balloon animals! For the next one I divided 45 by 15 and got 3 then I multiplied 20 by 3 and got 60 balloon animals! Hope this helps!
Answer:
well,the solution is x=4 y=0.... if that helps
Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).
Ok so f(x) and g(x) are the same thing as y. this means that you can solve these equations the same as any other multi-step equation. the only difference is if they have a number other than x in the parentheses. if they have a number you will just replace the x’s in the equation with the number in the parentheses.
example:
regular equation equation with f(4)
f(x)=2x+1 f(4)=2(4)+1

To divide fraction by number we can multiply fraction by inverse of number.
Lets find inverse
21=
=====>
- its inverse of 21
Now we can multiply it
- its our result
