Answer:
x=13
Step-by-step explanation:
The slope is defined as

So, we have the follwing equation:

Answer:
20 : 43
Step-by-step explanation:
width : length
40 mm : 86 mm
40 : 86
20 : 43
Let's say the numbers are "a" and "b"
hmm say "a" is the smaller, and "b" the greater
so "b" is "4 more than 5 times" "a"
so... 5 times "a" is 5*a or 5a
4 more than "that", will be "that" + 4
or
5a + 4
so.. whatever "a" is, "b" is 5a+4
now, their sum is 22, as opposed to "zz" hehe
so

solve for "a", to see what the smaller one is
what's "b"? well, b = 5a + 4
