Cathy has to deposit $410 worth of five- and tendollar
iogann1982 [59]
(# of five dollar bills=f ; # of ten dollar bills=t)
3t-1=f ⇒ this means that if there were 1 $5 bills, there would be 2 $10 bills.
So the ratio of $5 bills to $10 bills is 1 to 2.
We can plug that into another equation:
f+t=410 ⇒ I havent actually learned this in school yet so I just made a chart:         $10 ║ $5
------║------
2     ║ 1    = $25
4     ║ 2    = $50
6     ║ 3    = $75
8     ║ 4    = $100
10   ║ 5    = $125
and so on...
you probably found the pattern already, so you can conclude that [cathy deposited 16 five dollar bills and 33 ten dollar bills]

A
lso, you should probably check if there are any mistakes when going through this since I took almost an hour writing this.

To travel 80 miles, it takes Sue, riding a moped, 2 hours less time than it takes Doreen to travel 60 miles riding a bicycle. Su
andriy [413]

Answer:

Time taken by Doreen is 6 hours and speed is 10 miles per hour.

Time taken by Sue is 4 hours and speed is 20 miles per hour.

Step-by-step explanation:

Let the speed of Doreen be x

According to the question  speed of Sue   is = x+10

time  taken By Sue to cover 80 miles = \frac{80}{x+10}

time taken by Doreen to travel 60 miles = \frac{60}{x}

According to question Sue take two hours less than Doreen takes

therefore

\frac{60}{x} - \frac{80}{x+10} =2

\frac{60(x+10)-80x}{x(x+10)} =2

60(x+10) -80x = 2(x(x+10)

60x+600-80x = 2x^2+20x\\

simplifying it ,we get

2x^2+40x-600=0\\

Dividing both sides by 2 ,we get

x^2+20x-300=0\\

solving it for x ,we get

(x+30)(x-10) =0

x =-30 which is not possible

x =10 miles per hour

Speed of Doreen = 10 miles per hour

Speed of Sue = 10+10 = 20 miles per hour

Time taken by Doreen = 60 divided by 10 = 6 hours

Time taken  by Sue = 80 divided by 20 = 4 hours
