Given:
The equation is
[tex]\left(\dfrac{3}{5}\right)^x\left(\dfrac{5}{3}\right)^{2x}=\dfrac{125}{27}[/tex]
To find:
The value of x.
Solution:
We have,
[tex]\left(\dfrac{3}{5}\right)^x\left(\dfrac{5}{3}\right)^{2x}=\dfrac{125}{27}[/tex]
[tex]\left(\dfrac{5}{3}\right)^{-x}\left(\dfrac{5}{3}\right)^{2x}=\dfrac{5\times 5\times 5}{3\times 3\times 3}[/tex] [tex][\because \left(\dfrac{a}{b}\right)^{-m}=\left(\dfrac{b}{a}\right)^{m}][/tex]
[tex]\left(\dfrac{5}{3}\right)^{-x+2x}=\dfrac{5^3}{3^3}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]\left(\dfrac{5}{3}\right)^{x}=\left(\dfrac{5}{3}\right)^{3}[/tex]
On comparing the exponents, we get
[tex]x=3[/tex]
Therefore, the value of x is 3.

Step-by-step explanation:
Since it is a balance then both sides are the same, that is equal.
The 4 weights represented by circles can be written as 4w, then
4w = 25 ← equation representing the situation
Divide both sides by 4 to find w
w = 25 ÷ 4 = 6.25 ← the weight of 1 circle

Enter the numerical coordinates of the vertices of quadrilateral ABCD in the table. (Point A has been done for you.) Then predict the numerical
coordinates of the vertices of quadrilateral A'B'C'D' as the figure translates four different ways: 7 units up, 1 unit down, 4 units to the right, and 3
units to the left.
9514 1404 393
Answer:
up: (-3, 5); down: (-3, -3); right: (1, -2); left: (-6, -2)
Step-by-step explanation:
As you know, the coordinates of a given point tell you the distance ...
(right, up)
So, a displacement 7 units up adds 7 to the second coordinate value:
A(-3, -2) ⇒ A'(-3, -2+7) = A'(-3, 5) . . . . 7 units up
Likewise, 1 unit down subtracts 1 unit from the second coordinate value:
A(-3, -2) ⇒ A'(-3, -3) . . . . 1 unit down
__
Similarly, left-right changes affect only the first coordinate. Displacements right are added; displacements left are subtracted.
A(-3, -2) ⇒ A'(-3+4, -2) = A'(1, -2) . . . . 4 units right
A(-3, -2) ⇒ A'(-6, -2) . . . . 3 units left
Kendra just bought a new house and needs to buy new sod for her backyard. If the dimensions of her yard are 24.6 feet by 14.8 feet, what is the area of her yard? Do not include units (ft2) in your answer.
Given:
Dimensions of Kendra's yard are 24.6 feet by 14.8 feet.
To find:
The area of her yard.
Solution:
Let as consider,
Length of yard = 24.6 ft
Width of yard = 14.8 ft
We know that,
Area of a rectangle = Length × Width
Using the above formula, we get the area of her yard.
[tex]Area=24.6\times 14.8[/tex]
[tex]Area=364.08[/tex]
Area of her yard is 364.08 ft² and without including the units ft², we get 364.08.
Therefore, the area of her yard is 364.08.

6.78x - 5.2 = 4.33x + 2.15
HELPPP
Answer:
x = 3
Step-by-step explanation:
6.78x - 5.2 = 4.33x + 2.15
6.78x - 4.33x = 5.2 + 2.15
2.45x = 7.35
x = 7.35/2.45
x = 3
Thus, The value of x is 3

-5x-4y=2a 4x-5y=2 which of the following choices of A will results in a system of linear equations with exactly one solution
Answer:
Any of them. a ∈ RStep-by-step explanation:
-5x - 4y = 2a 4x - 5y = 2
-4y = 5x + 2a -5y = -4x + 2
y = (5x + 2a):(-4) y = (-4x + 2):(-5)
y = -⁵/₄x - ¹/₂a y = ⁴/₅x - ²/₅
m₁ = -⁵/₄, b₁ = -¹/₂a m₂=⁴/₅, b₂= -²/₅
-⁵/₄ ≠ ⁴/₅
Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.

Reading a Cartesian PlaneStep-by-step explanation:
When we label a Cartesian Plane, we label counterclockwise starting at the top right corner:
Top Right Corner = 1st Quadrant
Top Left Corner = 2nd Quadrant
Bottom Left Corner = 3rd Quadrant
Bottom Right Corner = 4th Quadrant
We see that point B is in the Bottom Right Corner. Therefore, it is in the 4th Quadrant and our answer would be D.
Answer:
B is in IV quadrant
Step-by-step explanation:
Count it conterclockwise, begin at the top right corner
The vertex of this parabola is at -5, -2. when the x-value is 4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation
Answer:
4/81 = a
Step-by-step explanation:
The vertex form of a parabola is
y = a (x-h)^2 +k where (h,k) is the is the vertex
y = a (x- -5)^2 -2
y = a (x+5)^2 -2
Substituting the point into the equation
2 = a( 4+5)^2 -2
2 = a( 9)^2 -2
2 = a (81) -2
Add 2 to each side
4 = 81 a
Divide each side by 81
4/81 = a
Answer:
a=4/81

-25/40+(64/40) as a fraction (simplest form)
Answer:
39/40
Step-by-step explanation:
-25/40 + 64/40 already has a common denominator so you just need to add the numerators. -25 +64 = 39 over the denominator of 40.
39/40
Step-by-step explanation:
-5/8 + 16/10 = -5/8 + 8/5 = -25+64/40 = 39/40
Simplify 7/3 - 4 V6 + 48 - 54.
(20 points)
Answer:
option B
Step-by-step explanation:
7 sq rt 3 cannot be simplified
4 sq rt 6 cannot be simplified
sq rt 48 = (sq rt 12 · sq rt 4) = (sq rt 4 · sq rt 4 · sq rt 3) = 4 sq rt 3
sq rt 54 = (sq rt 9 · sq rt 6) = 3 · sq rt 6
combine each pair of like terms: (7 sq rt 3 + 4 sq rt 3) = 11 sq rt 3
(-4 sq rt 6 - 3 · sq rt 6) = -7 sq rt 6
how do you isolate 1/2h -2 = -5
Answer:
Here is how to isolate the variable h.
Step-by-step explanation:
First, you have to isolate the variable which in this equation is "h." So you're going to add 2 to each side, which will give you
1/2h -2 + 2 = -5 + 2
1/2h = 3
now you've isolate the variable and you can solve for h.
(h = 6)
The i-Ready Answer:
h=14
The i-Ready Explanation:
1/2h-12= -5
+12 +12 ( Add 12 on both sides )
1/2h=7
2 x 1/2h=2 x 7 ( Multiply by 2 on both sides )
h=14

2 triangles are shown. The first triangle has side lengths x, x, 50. The second triangle has side lengths 45, 45, 75. What value of x will make the triangles similar by the SSS similarity theorem? 1.5 20 30 67.5
Answer:
30
Step-by-step explanation:
yes I can tell what it is
The value of x that will make the two triangles similar by the SSS similarity theorem is: C. 30.
What is the SSS Similarity Theorem?According to the SSS similarity theorem, if all the three corresponding sides of two triangles are proportional or have the same ratio, then both triangles are similar.
If the two triangles are similar we would have:
75/50 = 45/x
Cross multiply and find x
x = (45 × 50)/75
x = 30
Thus, the value of x would be: C. 30.

Calculate the marked price of a sweater purchased at Rs. 1075 allowing 14% discount. ( please do proper answer )
Answer:
Rs. 1250
Step-by-step explanation:
The sweater is purchased at Rs. 1075
The discount is 14%
Let y represent the marked price of the sweater
y × 14% = 1075
y × (100-14)/100= 1075
y × 86/100= 1075
y ×0.86= 1075
0.86y= 1075
Divide both sides by the coefficient of y which is 0.86
0.86y/0.86 = 1075/0.86
y = 1250
Hence the marked price is Rs. 1250
