Answer:
a=-8
b=-29
Step-by-step explanation:
Let's assume
first number is a
second number is b
the difference of two numbers,a and b,is 21
so, we get
we can solve for 'a'
the difference of five times a and two times b is 18
so, we get
now, we can plug 'a'
now, we can solve for b
now, we can find 'a'
I’m assuming that 7 means x, and honestly all you have to do is multiply. x= 1 , y= 75.. so just multiply 75 and 272. The answer is 20,400.

Answer:
the fox moves mn times as fast as the squirrel
Step-by-step explanation:
the easiest way to do problems like this is by using hypothetical values that make sense (it's best to avoid 0, 1, and 2)
we'll say that n = 3 and m = 4
so if the squirrel moves at <em>s</em> pace, then the rabbit moves at <em>ns</em>, or <em>3s.</em>
if the fox moves at m (4) times the rabbit's pace (3s), then it moves at <em>4(3s)</em>
then just switch out the numbers for their variables, giving you <em>m(ns) </em>
remember that s simply represents the squirrel's pace, we cannot replace it with a number in this case, so switch it with the idea/value it represents
and there you go, mn times the squirrel's pace
