<span>1. </span><span>The ratio of a wire that is cut
in to 2 is 5:9
The longer piece was 25cm. Now, find the total length and the length of the
shorter wire.
=> 5 : 9 = x : 25
=> First, let’s convert it to fraction
=> <u>5 </u>=<u> 9
</u> x 25
=> 25 (5) = x (9)
=> 125 = 9x
=> 125 / 9 = 9x / 9
=> 13.9 = x
Thus the ratio is approximately 5 : 9 = 13.9 : 25 </span>

Answer:
y = 3x -31
Step-by-step explanation:
y=mx+b
m=3
5 = 3*12 +b
b = 5 - 36
b = -31
y = 3x -31
Answer:
The easiest way to solve this system would be to use substitution since x is already isolated in the first equation. Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method
