Answer:
2/5
Step-by-step explanation:
0.4 = 4/10 which in simplest form is 2/5
Answer:
The answer is 31/100
Step-by-step explanation:
5/25 + 2/50 + 7/100 = 31/100
If you graph the two equations then you will find that they intersect at (-2,-2).
You then have to check your answer.
x=4y+6
(-2)=4(-2)+6
-2=-8+6
-2=-2
x-3y=4
(-2)-3(-2)=4
-2+6=4
4=4
8/15 x 5/6
•multiply across the numerator and denominator.
= 40/90
• then find a common factor that will go into both the numerator and denominator equally.
Common factor: 5
= 8/18
•there is another common factor, which is 2
Simplified:
=4/9
