Answer:
Thank you, person.
I hope this is good enough:
you want to talk about anything
just divide 20 by coefficient of x
x < 20/2
x < 10
Answer:
He have 43 bills of 10 and 13 bills of 5
Step-by-step explanation:
5x + 10y = 495
x + y = 56
Isolate x:
x = 56 - y
Substitute in the first equation:
5(56 - y) +10y = 495
280 -5y +10 y = 495
5y = 495 -280
5y = 215
y = 215/5
y= 43
Now substitute the value of y to find x:
x = 56 - y
x = 56 - 43
x = 13
Answer: The answer to that would be 4/5= 32/40.
Step-by-step explanation: It is 4/5 =32/40 because if you were to divide the 40 by the 5 you would get 8. Since you got 8 when dividing 40 by 5 you would multiply 8x4. You would do this because whatever you do to the denominator you would do to the numerator. So you would multiply 4/5 x 8/8 and get 32/40. PLEASE MARK BRAINLIEST!!!!
