Answer:
0=0
infinitely many solutions
Step-by-step explanation:
plug x=2y+3 as x into 3x-6y=9...so
3(2y+3)-6y=9, which has our x=2y+3 plugged in because that is what x equals
if you solve its
6y+9-6y=9
0y=0
y=0
making it 0=0
you can't go further from this
F=5 dollar bills
t=twent dollar bills
38 total bills
f+t=38
400 in bills
400=5f+20t
we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation
-5f-5t=-190
5f+20t=400 +
0f+15t=210
15t=210
divide both sides by 15
t=14
subsitute
t+f=38
15+f=38
f=23
23 five dolar bills
15 twenty dollar bills
14/15
5/15 + (3x3 / 3x5) = 5/15 + 9/15 = 14/25
Answer:
volume = length×breadth×height
3×4×4=48in cube
Answer:
Step-by-step explanation:
Given that 
is the repeating decimal.
The repeating decimal is converted into the fraction as
:
<=> 0.121212 = 
Multiplying both sides by x, we have,
<=> 0.121212x = 3
Dividing both sides by 0.121212, we get:
<=> x = 
<=> x = 25
So the fraction represents the decimal is:
Hope it well find you well.
