1min(1*140)/35=4min
it takes 4min to type 140 words
Step-by-step explanation:
90 -t = 10
10t = 90
10 + 90 = t
9t = 90
The required equation for the tickets Molly buys is 10t = 90.
An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Price of one ticket bought by Molly = $10,
Also,
Amount spent by Molly on tickets = $90.
To find the equation,
Let Molly buys t concern tickets,
Since, the price of one ticket is $10,
Total price for tickets = 10t
The total amount is $90,
So, the equation can be written as,
10t = 90

Answer: a.) 15 and 89/99
b.) 10/99
Step-by-step explanation:
a.) 15.898989...
Let x = 0.898989...
100*x = 89.8989...
100x - x = 89.898989... - 0.898989...
99x = 89
x = 89/99
So 15.898989.... = 15 and 89/99
b.) 0.101010
Y= 0.101010
100y = 10.101010...
100y - y = 10
99y = 10
y = 10/99
