Answer:
<em>The temperature in Miami is 9/5 times the temperature in San Diego.</em>
Step-by-step explanation:
<u>Ratios</u>
To compare the temperature in Miami (45) with the temperature in San Diego (25), we use the division or ratio between both numbers:

Simplify the fraction dividing by 5:

Since the relation between them is 9/5, it means the temperature in Miami is 9/5 times the temperature in San Diego.
Athe answer is -2 because it is behind the 0 and will be negative and it is two lines away from the 0 so the answer is -2
Multiply 2x-5y= -21 by 3 to make it 6x-15y= -63
Multiply 3x-3y= -18 by -5 to make it -15x+15y=90
This cancels the y’s out which leaves us with
6x=-63
&
-15x=90
x for 6x=-63 equals - 10.5 so x is - 10.5 and for -15x=90, x= -6
Then you plug in x into any equation you’d like to find y.
Let’s plug in - 10.5 into 6x... equation.
6(- 10.5)-15y=-63
63-15y= -63
-63 -63
-15y=0
y=0 and x= - 10.5. When you plug in this values it makes the equation true!
But the correct answer is the first one north. Sorry if I’m doing too much hahah
If I’m confusing here’s the right answer...
6x-15y= -63
-15x+15y=90
