Answer:
x = 1/5
y = 6
Step-by-step explanation:
System:
{5x + y = 7
{20x + 2 = y
First equation:
5x + y = 7 -> y = -5x + 7
Plug into second equation:
20x + 2 = -5x + 7
Subtract 2 from both sides:
20x = -5x + 5
Add 5x to both sides:
25x = 5
Divde both sides by 25:
x = 5/25 -> 1/5
~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Come back to the first equation:
5x + y = 7
Plus in our x:
5(1/5) + y = 7
Multiply:
1 + y = 7
Subtract 1 from both sides:
y = 6
Hope this helps, have a nice day! :D
Answer:
The difference is 1
Step-by-step explanation:
Because the ratio is 5:4, there are 5/4 times as many adult cats as kittens, or 4/5 times as many kittens than adult cats.
So you do:
24 × 5/4
= 24/1 × 5/4
= 120/4
= 30
31 - 30 = 1
