Randy has to raise $50.00 to repair his bicycle. He is only $1.00 short. He has only $1 and $5 bills. If he has one more $1 bill
Nezavi [6.7K]

Answer:

Randy has eight $5 bills and nine $1 bills

Step-by-step explanation:

Randy needs $50.00

And we know that he his only $1.00 short, so he has $49.00

let's define:

x = number of $1 bills that he has

y = number of $5 bills that he has.

then:

x*$1 + y*$5 = $49

We know that he has one more $1 bills than $5 bills.

we can write this as

x = y + 1

So we have a system of two equations and two variables:

x*$1 + y*$5 = $49

x = y + 1

First we can see that the variable "x" is isolated in the second equation, now we can replace that in the other equation:

x*$1 + y*$5 = $49

(y + 1)*$1 + y*$5 = $49

now we can solve this for y.

y*$1 + $1 + y*$5 = $49

y*($1 + $5) = $49 - $1 = $48

y*$6 = $48

y = $48/$6 = 8

He has 8 $5 bills

and we know that:

x = y + 1

x = 8 + 1 = 9

he has 9 $1 bills.

last minute forgot to do it please help and do all of them and I have one more I promise I’ll give you good ratings :D
Zolol [24]

1.) The error is that she attached the

variable with the flat fee (which is

constant) and put the daily rent as a

constant (which is variable).

The correct equation is:

365+125x=250+175x

2.) N=5

3.) k=-35.

Explanation: Solution:

17k-6=37k+4 . 17k-37k=4+6 .

-27k=10 . k=10\cdot(7-2) . k=-35 .

4.)

y =   - \frac{9}{16}
