Answer:
27
Step-by-step explanation:
Evaluating this expression according to the order of operations is a straightforward calculator problem.
= (81 ÷ 27)³ = 3³ = 27
__
You can also use the rules of exponents to simplify this before evaluating.
(a^b)^c = a^(bc)
(a^b)/(a^c) = a^(b-c)
__
= ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

The perimeter of an equilateral triangle is 3 (+ 5). The perimeter of a rectangle is 2 (2x - 3) + 2(2). If the perimeters of the two figures are equal, then what is the value of r?
Answer:
3.25
Step-by-step explanation:
Perimeter of triangle = 3(5) = 15 cm
Perimeter of rectangle = 2(2x - 3 + 4)
Perimeter = 2(2x + 1)
Perimeter = 4x + 2
4x + 2 = 15
4x = 15 - 2
4x = 13
x = 13/4
x = 3.25

Step-by-step explanation:
1 - 5 is not equal to 8

DF= 78, DE = 5x -9, EF = 2x + 10, find DE.
Solve for x first.
5x - 9 + 2x + 10 = 78
7x + 1 = 78
7x = 78 - 1
7x = 77/7
x = 11
Then substitute the value of x to find DE.
DE = 5x - 9
5(11) - 9
55 - 9
DE = 46
Therefore, the value of DE is 46
DF= 78, DE = 5x -9, EF = 2x + 10, find DE.
Solution:First, solve for the value of x.
DE + EF = DF(5x - 9) + (2x + 10) = 787x + 1 = 787x = 78 - 17x = 77/7x = 11Then, plug and substitute the value of x to find the DE.
DE5x - 95(11) - 955 - 946Answer:The value of DE is 46Find the equation of the line that passes through the point
(4, 11) and is perpendicular to y= 4/3x + 7
Answer:
y = -3/4x + 14
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal of the original line.
4/3x -> -3/4x
Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].
11 = -3/4(4) + b
11 = -3 + b
14 = b
Put everything we know and solved for back into the expression.
y = -3/4x + 14
Best of Luck!
Subtract: (4x3 + 9xy + 8y) – (3x3 + 5xy – 8y)
(4x³ + 9xy + 8y) - (3x³ + 5xy - 8y) =
= 4x³ + 9xy + 8y - 3x³ - 5xy + 8y =
= 4x³ - 3x³ + 9xy - 5xy + 8y + 8y =
= x³ + 4xy + 16y ← the end answer

Isolate the variable by adding a constant to each side of the equation 4(x-5)=25
Answer:
ummm I think u want the answer x= 11 1/4
Answer:
x = 45/4
Step-by-step explanation:
4(x - 5) = 25
4x - 20 = 25
4x - 20 + 20 = 25 + 20
4x = 45
4x/4 = 45/4
x = 45/4

Find the length of PQ if PQ = QR
Answer and Step-by-step explanation:
To find the length of PQ, we need to set the length of PQ equal to the length of QR (since in the question it tells us that PQ is equal to QR).
PQ = QR
x + 1 = 12
Solve for x.
Subtract 1 from both sides of the equation.
x + 1 - 1 = 12 - 1
x = 11
Now plug this number into the expression length for PQ.
11 + 1 = 12
The length of PQ is 12.
(you can also see that QR has a length of 12, so we can just say that PQ 12).

four cities lie along a straight highway in this order city a, city, city c, city d. The distance from city a to city b is 5 times the distance from city b to city c. The distance from city a to city d is 2 times the distance from city a to city d. the distance between city d and city c is 10 miles. What are the distances between the cities?
Dividing the segments and finding the lengths, it is found that the distance between the two cities is of 130 miles.
--------------------------------
We want to find the distance between cities a and d.Due to the cities along the highway, the distance is given by:[tex]ad = ab + bc + cd[/tex]
--------------------------------
The distance from city a to city b is 5 times the distance from city b to city c, and thus:[tex]ab = 5bc[/tex]
In terms of x, [tex]bc = x, ab = 5x[/tex]
--------------------------------
The distance from city b to city c is 2 times the distance from city c to city d, and thus:[tex]bc = 2cd[/tex]
In terms of x, [tex]cd = \frac{x}{2}[/tex]
--------------------------------
The distance between city d and city c is 10 miles, thus:[tex]\frac{x}{2} = 10[/tex]
[tex]x = 20[/tex]
--------------------------------
The other distances are:[tex]bc = x = 20[/tex]
[tex]ab = 5x = 5(20) = 100[/tex]
--------------------------------
The distance between cities a and d is:[tex]ad = ab + bc + cd = 100 + 20 + 10 = 130[/tex]
The distance between the two cities is of 130 miles.

What pattern can you see in the graph of y = 10x for x ≥ 0?
Graphs are used to show the relationship between two variables. In the given graph, as the value of x increases, the value of y decreases.
Given that:
[tex]y = \frac{10}{x}[/tex]
The above function is an inverse function.
This means that:
As the value of x increases, the value of y decreases
Take for instance:
[tex]x= 1[/tex]
[tex]y = \frac{10}{1} = 10[/tex]
Now, [tex]x = 2[/tex]
[tex]y = \frac{10}{2} = 5[/tex]
Notice that:
As x increases from 1 to 2, the corresponding values of y decreases from 10 to 5
Hence, (b) is correct
