If you would like to write 45 minutes to 1 hour in the simplest form, you can do this using the following step:
1 hour = 60 minutes
45 minutes : 60 minutes = 45 : 60 = 3 : 4 (divide both numbers by 15)
The correct result would be 3 : 4.
Answer:
x=5,y=3
Step-by-step explanation:
the first step is to decide whether you want to substitute y and find x, or substitute x and find y.
(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).
for example, let's substitute y into the first equation:
x=17-4*(x-2)
so now,we will organize the equation:
x+4x=17+8
5x=25/(÷5)
x=5
now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:
y=5-2
y=3
