Answer:
20 cats
Step-by-step explanation:
A proportion has to be setup to answer this
5/4 = 25/x
x represents the missing number of cats
This fraction represents the relationship amongst dogs and cats
----
To solve cross multiply
5x = 100
(let me down below if you need an explanation on how to cross multiply)
Divide both sides by 5 in order to get the variable by itself
100/5 = 20
x = 20
The shelter has 20 cats

Answer:
2
Step-by-step explanation:
Let, the number be 'x'.
As per question,
4×x+3=11
subtracting 3 on both sides,
4x=8
dividing by 4 on both sides
x=2.
hence, the number is 2.
Answer:
y = 4x
Step-by-step explanation:
We need to look at where the line's dots are to find the slope. Between each dot the line goes 1 to the right and 4 up. Remember the saying rise over run to know that the slop is 4/1. 4/1 is just 4 so in the equation we put that next to x.
The next part of making an equation is the y-intercept, or where it crosses the y-axis. Since this hits the y-axis at 0 the complete equation will be
y = 4x + 0
but obviously we don't need to add 0 so the answer is
y = 4x
