Answer:
744/40=18.6
Step-by-step explanation:
the 1 in 18.6 is in the 10ths place
the 8 in 18.6 is in the ones place
the .6 in 18.6 is in the -ones place
Answer:
33 ¹/₃ seconds
Step-by-step explanation:
Since the dog is 30 - 24 = <em>6 m/s faster than the cat</em>, that means that the dog is <em>6 meters closer to the cat each second</em>.
So, that gap will close in 200/6 = 33 ¹/₃ seconds.
it is 529 plan
a 529 plan is a saving plan designed to encourage saving for future education.
The sale per linear feet is $16.75.
First, we need to find the total amount of sales, so we have to subtract the returns and discounts.
10342 - 217 - 599 = 9529
Now, divide this amount by the amount of linear feet.
9529 / 575 = 16.57
Make a system of equation before finding the numbers. d stands for denominator and n stands for the numerator.
⇒ d = n - 4 (first equation)
⇒ (n + 3)/(d + 3) = 2 (second equation)
Simplify the second equation
(n + 3) / (d + 3) = 2
(n + 3) = 2(d + 3)
n + 3 = 2d + 6
Solve the equation system by subtituting d with n-4 from the first equation into the second equation
n + 3 = 2d + 6
n + 3 = 2(n - 4) + 6
n + 3 = 2n - 8 + 6
n + 3 = 2n - 2
n - 2n = -2 - 3
-n = -5
n = 5
The original numerator is 5
Find the original denominator by inputing 5 as numerator to one of the equation
d = n - 4
d = 5 - 4
d = 1
The original denominator is 1
So the original fraction is 5/1
