Susan is buying a ring that is regularly $54. 95 and is on sale for 1/2 off. Which expression can Susan use to estimate the amount of the discount on the ring?.

136 / 8 = 34 / 2 = 17

so yes, just simple division to get the answer, 17 buttons per container

please give brainliest

Answer:

yes she could and the answers 17

Step-by-step explanation:

because to find if a number is divisible by eight in a three-digit number u add the first two digits and multiply it by the last. In this case, we add 1 and 3=4 and multiply it by 3=24 and because 24 is divisible by 8 the number 136 can be divided by 8

Answer:

Factor 3x^2-17x-20, and you get (x + 1)(3 x - 20)

x = 17/6 + sqrt(1729)/6, x = 17/6 - sqrt(1729)/6

Step-by-step explanation:

Factor 3x^2-17x-20, and you get (x + 1)(3 x - 20)

When 3x^2-17x-20 is equal 100

3x^2-17x-20=100

Subtract both sides by 100

3x^2-17x-120=0

Use the quadratic formula

x = 17/6 + sqrt(1729)/6, x = 17/6 - sqrt(1729)/6

Answer:

y=-5x+35

Step-by-step explanation:

Use the formula y = mx + b

m = slope, so plug in -5 as the slope

To find x-intercept we set y=0

We want the x-intercept to be 7 so we can plug that into the equation too

0=-5(7)+b

Answer:

-10/3 = n

Step-by-step explanation:

let 'n' = number

2(n-7) = 5n-4

distribute the 2 to eliminate the parentheses:

2n - 14 = 5n - 4

subtract '2n' from each side to get:

-14 = 3n - 4

add 4 to each side to get:

-10 = 3n

-10/3 = n

Answer:

Cathy drove  21.5 miles  to work after 5 days

Explanation:

Each day she drove = [tex]4\frac{3}{10}[/tex] miles .......each day is 1 day.

1 days ---> 4.3 miles

So 5 days ---> ( [tex]4\frac{3}{10}[/tex] * 5 ) miles

                     = [tex]\frac{43}{10}[/tex] * 5

                     = 4.3 * 5

                      = 21.5 miles

Answer:

It asking how many miles it drone each day which is 21.5.

Step-by-step explanation:

You just multiply 4 3/10 to 5 and you get 21.5

Answer:

  a = -5

Step-by-step explanation:

You want the solution to the equation a -6/3 = -7.

The improper fraction -6/3 can be written as -2, so the equation is ...

  a -2 = -7

  a = -5 . . . . . . . add 2 to both sides

__

Additional comment

If you intend the equation to be ...

  (a -6)/3 = -7

The first step can be multiplication by 3:

  a -6 = -21

  a = -15 . . . . . . . add 6 to both sides

If the equation is typeset as ...

  [tex]\dfrac{a-6}{3}=-7[/tex]

the fraction bar serves the purpose of grouping the terms of the numerator. When this is written in plain text, the typographic grouping clues are lost, and parentheses are needed.

The measure of the largest exterior angle of the quadrilateral is 120 degrees

Quadrilateral are polygons that have four sides. They are regarded as a four sided polygon.

Therefore, the measures of the exterior angles are as follows;

The sum of all the exterior angles of a quadrilateral is 360°. Therefore,

3x + 8x + 9x + 10x = 360°

30x = 360

x = 360 / 30

x = 12

Therefore, the greatest/largest exterior angle is as follows;

Answer:

18x² + 48x - 50

Step-by-step explanation:

Area of rectangle = width x length

Area of square = width²

Therefore, area of park not occupied by the turtle park would be the area of the rectangular park MINUS the area of the turtle pond:

= (3x + 7)(6x + 2) - 8²

= 18x² +42x + 6x + 14 - 64

= 18x² + 48x - 50

The inverse of a function is the opposite of the function

1) y = log2 (3x)

Swap the positions of x and y

[tex]x = \log_2(3y)[/tex]

Apply the exponential rule

[tex]2^x = 3y[/tex]

Make y the subject

[tex]y = \frac{2^x}3[/tex]

Hence, the inverse function is: [tex]y = \frac{2^x}3[/tex]

2) y=log3(x-1)

Swap x and y

[tex]x = \log_3(y - 1)[/tex]

Apply exponent rule

[tex]3^x = y - 1[/tex]

Make y the subject

[tex]y = 3^x + 1[/tex]

Hence, the inverse function is: [tex]y = 3^x + 1[/tex]

3) y=-2log x

Swap x and y

[tex]x=-2\log y[/tex]

Divide both sides by -2

[tex]-0.5x=\log y[/tex]

Apply exponent rule

[tex]y = 10^{-0.5x}[/tex]

Hence, the inverse function is: [tex]y = 10^{-0.5x}[/tex]

4) y=log6(3x)

Swap x and y

[tex]x = \log_6(3y)[/tex]

Apply exponent rule

[tex]3y = 6^x[/tex]

Make y the subject

[tex]y = \frac{6^x}{3}[/tex]

Hence, the inverse function is: [tex]y = \frac{6^x}{3}[/tex]

5)y=log3(x+2)

Swap x and y

[tex]x = \log_3(y + 2)[/tex]

Apply exponent rule

[tex]y + 2 = 3^x[/tex]

Make y the subject

[tex]y = 3^x - 2[/tex]

Hence, the inverse function is: [tex]y = 3^x - 2[/tex]

6) y=log3(5^3)

Swap x and y

[tex]x = \log_3(5^3)[/tex]

Hence, the inverse function is: [tex]x = \log_3(5^3)[/tex]

7) y=6^x+5

Swap x and y

[tex]x = 6^y + 5[/tex]

Subtract 5 from both sides

[tex]6^y = x - 5[/tex]

Apply logarithm

[tex]y = \log_6(x - 5)[/tex]

Hence, the inverse function is: [tex]y = \log_6(x - 5)[/tex]

9) y=log3 2^x

Swap x and y

[tex]x = \log_3(2^y)[/tex]

Apply exponent rule

[tex]2^y = 3^x[/tex]

Apply logarithm

[tex]y = \log_2(3^x)[/tex]

Hence, the inverse function is: [tex]y = \log_2(3^x)[/tex]

10) y=3^x -7

Swap x and y

[tex]x = 3^y - 7[/tex]

Add 7 to both sides

[tex]3^y = x + 7[/tex]

Apply logarithm

[tex]y = \log_3(x + 7)[/tex]

Hence, the inverse function is: [tex]y = \log_3(x + 7)[/tex]
