==========================================
Work Shown:
A = 50 = number of words typed in 1 minute
B = 1 minute
C = 500 words
D = x minutes (needed to type 500 words)
A/B = C/D
50/1 = 500/x
50*x = 1*500 ... cross multiply
50x = 500
x = 500/50 .... divide both sides by 50
x = 10
You'll need 10 minutes to type 500 words
------------
Alternative approach:
50 words = 1 minute .... given speed
1 word = 1/50 minute ... divide both sides by 50
1 word = 0.02 minute
500 words = 10 minutes .... multiply both sides by 500
As per the given data, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.
If you have a typing speed of 50 words per minute, it means you can accurately type 50 words in one minute. This rate is often considered an average typing speed for proficient typists.
If I can type 50 words per minute, then to determine the number of minutes it would take to type a 500-word essay, we can divide the total number of words by the typing speed:
Time (in minutes) = Total words / Typing speed
Time = 500 words / 50 words per minute
Time = 10 minutes
Therefore, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.

Solve -1/6 (3x – 9) – 9= 3.
The solution is x=
Please explain
Answer:
x=23
Step-by-step explanation:
1/6 as a decimal is 0.16666667 but i rounded it to 0.2
so the equation is the 0.2(3x-9)-9=3
then i did 0.2 times 3x =0.6x
then 0.2 times -9= -1.8
so the equation now looks like this:
0.6x-1.8x-9=3
so i add 1.8 and 9 to 3 which gives you 13.8
then the equation looks like this:
0.6x=13.8
then you do 13.8 divided by 0.6 which equals 23.

what is the factor of 6a2 – 19a + 10 ???
Answer:
(2a - 5) • (3a - 2)
step by step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60
Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .
-60 + -1 = -61
-30 + -2 = -32
-20 + -3 = -23
-15 + -4 = -19 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4
6a2 - 15a - 4a - 10
Step-4 : Add up the first 2 terms, pulling out like factors :
3a • (2a-5)
Add up the last 2 terms, pulling out common factors :
2 • (2a-5)
Step-5 : Add up the four terms of step 4 :
(3a-2) • (2a-5)
Which is the desired factorization
Final result :
(2a - 5) • (3a - 2)

Rakim charges $2 per hour for tutoring plus a $7 fee.
Joan charges a $3 fee plus $4 per hour.
When will their tutoring fees be the same (aka equal)
How many hours of tutoring will occur before the fees are the same?
How much has each person been paid in tutoring fees?
Answer:
after 2 hours, they will have the same fee.
they will have been payed 11$
Step-by-step explanation:
if you say h = hours of tutoring,
Rakim charges 7 + 2h
Joan charges 3 + 4h
since you want them to be the same, you can write the following equation:
7 + 2h = 3 + 4h
subtract 2h from each side
7 = 3 + 2h
subtract 3 from each side
4 = 2h
divide both sides by 2.
h = 2
after 2 hours, they will have the same fee.
they will have been payed 11$
"they will have been payed" ah yes the grammar.

Answer: She can make 12 batches of brownies. There is a slight remainder, but think about it like this, if you only had a spoon full of sugar left, do you think you could make an entire batch of brownies? No. So if you see problems like this, the whole number should be the answer (unless asked otherwise).
Step-by-step explanation: Since 3/4 is like 75 out of 100, the decimal form is .75 and we all know (or should know) that 1/2 can be put as .5. Whenever there's a whole number before the fraction, and you want to convert the fraction into a decimal, the whole number will go before the decimal. So after converting the fractions to decimals, the problem is 9.5 divided by .75 which is 12.6. Like I said before, that remainder .6 can't make an entire batch of brownies, so we just go with the whole number 12.

On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is . How long will it take the airplane to travel 800 miles? Do not include units (hours) in your answer.
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question
On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?
Speed is the change in distance if a body with respect to time. It is expressed mathematically according to the question as t = 1/500 × d
To determine the time it will take to travel 800miles, we will substitute d = 800 into the modeled equation.
t = 1/500 × 800
t = 800/500
t = 8/5
t = 1.6
