－81＝3(5－4r)
27＝－(5－4r)
27＝－5＋4r
－4r＝－5－27
－4r＝－32
r＝8
Hope my answer helped u :)
Answer:
The simplest form of the fraction 
is 
.
i.e.
Step-by-step explanation:
Here are some simple observations regarding how to reduce a fraction into simpler terms:
- A fraction is reduced to lowest or simplest terms by finding an equivalent fraction in which the numerator and denominator are as small as possible.
- In order to reduce a fraction to lowest or simplest terms, divide the numerator and denominator by their (GCF). Note that (GCF) is also called Greatest Common Factor .
So, lets take a sample fraction and reduce into simpler terms.
Considering the fraction
so
Therefore, the simplest form of the fraction is .
i.e.
formula for a diagonal line in a square is D = Square root of 2 times the length of the side
so square root of 2 times 300 = about 424 feet. the answer is the last one
Answer:
1200+(1200x13:100)=1356
1200 = original
(1200x13:100) = 13%
want to know % of the new number = orignal x % : 100
Answer: she ran 3.53km on the third day.
Step-by-step explanation:
Let x represent the number of miles that she ran on the second day.
The first day, she ran 1.37 km more than she ran on the second day. This means that the distance that she ran on the first day is
x + 1.37
On the third day, she ran 0.98 km more than the second day. This means that the distance that she ran on the third day is
x + 0.98
The total distance that she wants to run in 3 days is 10km. This means that
x + 1.37 + x + x + 0.98 = 10
3x + 2.35 = 10
3x = 10 - 2.35
3x = 7.65
x = 7.65/3
x = 2.55
The distance that she ran on the third day is
2.55 + 0.98 = 3.53 km
