What is reciprocal of the fraction in the equation 3/5(2x+8)=18?

81 = x²

√81 = x

√9 × 9 = x

9 = x

Verification :-

9 × 9 = 81

9² = 81.

So, the value of x is 9.

Answer:

X = ± 9

Step-by-step explanation:

81 = x² , that is

x² = 81 ( take the square root of both sides )

x = ± [tex]\sqrt{81}[/tex] = ± 9

As a check

9² = 9 × 9 = 81 and (- 9) × (- 9) = 81

Sum of three angles=180°

[tex]\\ \rm\hookrightarrow x+x+10+2x-10=180[/tex]

[tex]\\ \rm\hookrightarrow 4x=180[/tex]

[tex]\\ \rm\hookrightarrow x=45[/tex]

Answer:

147 hummingbirds are in the sanctuary.

Step-by-step explanation:

The answer can be found using the given percentage. Stating that 35% of the birds in the sanctuary are hummingbirds means that the amount of hummingbirds is 0.35 times the total amount of birds.

[tex]420 \: \times \: 0.35 \: = 147[/tex]

Percentages can always be converted to a decimal number:

(1% = 0.01 ; 10% = 0.10 ; 100% = 1.00; etc.)

1 2 and 1/3 least common denominator

What is the least common denominator? LCD in math

The LCD of 1/2 and 1/3 is 6, because LCM(2, 3) = 6;

Knowing the LCD, you can find equivalent fractions to yours 1/2 and 1/3, with the denominator equal to found LCD:

Answer:

12.

Step-by-step explanation:

One way to find the LCD is from the prime factors:

4 =  2*2

6 = 2*3

One '2' occurs in both sets, so we only include one of these 2's, so the LCD

= 2*2*3

= 12.

Answer:

9 fish

Step-by-step explanation:

If each fish costs 4 dollars, and we can spend at most 36 dollars, we can find out that we can buy 9 fish by dividing 36/4, which gives you the answer of 9.

We can model this problem by doing

4x = 36

Divide by 4 on both sides to isolate the x

x = 9

Answer:

4x ≤ 36

x ≤ 9

(X2+5)(3x2-2)

Step-by-step explanation:

=(3x4-2x2)+(15x2-10)

X2(3x2-2)+5(3x2-2)

(X2+5)(3x2-2)

Answer:

Length: 9 inches per side

Width: 3 inches per side

Step-by-step explanation:

Perimeter = 2*width + 2*length  

Perimeter = (2 x W) + (2 x 3W) = 8W.  

Since we know P = 24, it is also = 8W

With 24=8W, divide each side by 8, and W = 3.  

So if W=3, the width is 3 inches, and the length is 3W, or 3x3 which is 9.

Answer:

The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. To find the slope, use the distance formula. The distance formula is Y2-Y1/X2-X1. You can use any two points on the graph but I will use (0,4) and (3,6).

6-4/3-0

2/3

The slope is 2/3. To find the y-intercept, look at the graph and find the where the line crosses the y-axis. The y-intercept in 4. So, the equation of this line is y=2/3x+4.

:)

Answer:

[tex]y=\boxed{\dfrac{2}{3}}\:\:x+\boxed{4}[/tex]

Step-by-step explanation:

Slope-intercept form of a linear equation:

  [tex]y = mx + b[/tex]

where:

To find the slope of the given line, define two points on the line:

Substitute the two defined points into the slope formula and solve for m:

[tex]\implies \textsf{slope}\:(m)=\dfrac{4-0}{0-(-6)}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]

The y-intercept is y-value of the point at which the lines crosses the y-axis.  From inspection of the graph, the y-intercept is 4.

Therefore, substitute the found slope and y-intercept into the slope-intercept formula to create the equation of the given line:

[tex]\implies y=\dfrac{2}{3}x+4[/tex]

Answer:

[tex]u_{n}[/tex] = - 5.6n + 3.2

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

[tex]u_{n}[/tex] = u₁ + (n - 1)d

where u₁ is the first term and d the common difference

To find u₁ use the given recursive formula

u₁ = u₀ - 5.6 = 3.2 - 5.6 = - 2.4

from the recursive formula d = - 5.6 , then explicit formula is

[tex]u_{n}[/tex] = - 2.4 - 5.6(n - 1) = - 2.4 - 5.6n + 5.6 = - 5.6n + 3.2

Step-by-step explanation:

In order to subtract these two polynomials, you first have to change all the signs in the second parenthesis. Now you should have:

(2.1x + 2.6) - (5x + 4).

Next if you are subtracting vertically (it's easier this way, if you do) line up the like terms, like so⤵⤵⤵:
