The answer is 200 because you multiply 20x12 you get 200
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
Hence missing value in the solution to the equation is:(-5,2)
Step-by-step explanation:
We are given the equation:
and we need to complete the missing value in the solution to the equation
(-5,?)
Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)
So, x= -5, Now finding y:
Putting value of x in given equation:
So, value of y is 2
Hence missing value in the solution to the equation is:(-5,2)
