reduce [tex]\frac{54}{81}[/tex]
Answer:
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Step-by-step explanation:
Fraction Reduction
To reduce a fraction, we try to divide both the numerator and denominator by the very same number until no more numbers can be found.
The fraction to reduce is:
[tex]\displaystyle \frac{54}{81}[/tex]
Since the denominator is odd, we cannot divide by 2, but we can divide by 3:
[tex]\displaystyle \frac{54}{81}=\frac{18}{27}[/tex]
We divide by 3 again:
[tex]\displaystyle \frac{18}{27}=\frac{6}{9}[/tex]
We divide by 3 one last time:
[tex]\displaystyle \frac{6}{9}=\frac{2}{3}[/tex]
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]

Solve the equation for n
3(n-5) = -21
Answer:
n=−2
Step-by-step explanation:
Let's solve your equation step-by-step.
3(n−5)=−21
Step 1: Simplify both sides of the equation.
3(n−5)=−21
(3)(n)+(3)(−5)=−21(Distribute)
3n+−15=−21
3n−15=−21
Step 2: Add 15 to both sides.
3n−15+15=−21+15
3n=−6
Step 3: Divide both sides by 3.
Answer: n= -2
Step-by-step explanation:
3(n−5)=−21
Divide both sides by 3.
n−5=
3
−21
Divide −21 by 3 to get −7.
n−5=−7
Add 5 to both sides.
n=−7+5
Add −7 and 5 to get −2.
n=−2

Find the greatest common factor of 15y^3 and 9n^4
The answer is 3. The only common factor between the numbers is 3, because 15 is 3 times 5, while 9 is 3 times 3.
Answer:
Greatest common factor: 3
Step-by-step explanation:
Both 15 and 9 have a factor of 3, and that is the biggest number that they share. The answer doesn't have letters in it because y and n are not related.

Find the measure of A if Bis 38 100° B. A
In the diagram below, all measurements are given correct to the nearest cm. Calculate the greatest possible area of the shaded region.
The possible area of the region that is shaded is given as 462cm.
How to solve for the area of the shaded regionThe picture here shows us two rectangles.
The area of a rectangle is given as L * w
= length x width
We have to find the area of the first rectangle
21cm x 42cm
= 882 cm
Next we find the area of the rectangle inside
15cm x 28cm
= 420
To get the area of the shaded region
= 882 - 420
= 462cm

Answer: f(-5)= 7
Step-by-step explanation:
The x value is -5 so look for the y value of the x value which is 7
Answer:
f(-5) = 7
Step-by-step explanation:
f(x) is referring to the y value, so what it is equal to would be the x value at that spot
in this case the y value is -5 so the x value is 7
(1) 5 years ago a man's age was 5 times the age of his daughter's. 3 years hence, twice
his
age will be equal to 6 times his daughter's age. Find their present ages.
Answer: Daughter = 13, Man = 45
Step-by-step explanation:
Today 5 yrs ago 3 years hence (future)
Man x x - 5 x + 3
Daughter y y - 5 y + 3
5 years ago a man's age was 5 times the age of his daughter's
EQ1: x - 5 = 5(y - 5) → x - 5 = 5y - 25 → x - 5y = -20
3 years hence, twice the man's age will be equal to 6 times his daughter's age.
EQ2: 2(x + 3) = 6(y + 3) → 2x + 6 = 6y + 18 → 2x - 6y = 12
Solve the system of equations using the Elimination method:
EQ1: x - 5y = -20 → -2(x - 5y = -20) → -2x + 10y = 40
EQ2: 2x - 6y = 12 → 1(2x - 6y = 12) → 2x - 6y = 12
4y = 52
÷4 ÷4
y = 13
Substitute y = 13 into either equation to solve for x:
EQ1: x - 5y = -20
x = 5y - 20
x = 5(13) - 20
x = 65 - 20
x = 45

Solve 24>−3r≥−9. please
Answer:
−8<r≤3
Step-by-step explanation:
The final inequality of 24>−3r≥−9 is -8 < r ≤ 3.
Given,
24>−3r≥−9
We need to solve this inequality.
What are inequalities?We have,
< = less than
> = greater than
≤ = less than and equal
≥ - greater than and equal
If we change the sign we change the inequality.
Example:
2 > -1
Multiply -1 on both sides.
-2 < 1
We have,
24 > -3r ≥ -9
We can cancel the common factor.
3 x 8 > -3r ≥ - 3 x 3
8 > -r ≥ -3
Multiply - on all sides.
-8 < -(-r) ≤ -(-3)
-8 < r ≤ 3
This means r values are between -8 and 3.
r = ( -8, 3]
Thus the final inequality of 24>−3r≥−9 is -8 < r ≤ 3.
