Answer:  

member = 15

nonmember = 55

Step-by-step explanation:

m = member, n= nonmember

1m+6n=345

2m + 2n =140 (divide all by 2 )

m + n = 70

m= 70 - n

70-n + 6n =345

70 + 5n = 345

5n = 345-70

5n = 275

n = 275÷5

n = 55

m = 70 - 55 = 15

m=15

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

(8)

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (8, 2)

m = [tex]\frac{2-2}{8+3}[/tex] = [tex]\frac{0}{11}[/tex] = 0

A slope of zero indicates the line is horizontal and parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (- 3, 2) and (8, 2) with y- coordinates 2, thus

y = 2 ← equation of line

(9)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 3, 2)

m = [tex]\frac{2-1}{-3+6}[/tex] = [tex]\frac{1}{3}[/tex] , then

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 2) , then

2 = - 1 + c ⇒ c = 2 + 1 = 3

y = [tex]\frac{1}{3}[/tex] x + 3 ← equation of line

The dimensions of the cropped photo will be 9 inches by 9 inches

Step-by-step explanation:

From the formula of area of square

Length x width = area

[tex]x^{2}[/tex] = area

But we are given the equation as

[tex](x+2)^{2}[/tex] = 121

The equation gives the measures of the cropped dimension as "x". This means we need to solve the equation

[tex](x+2)^{2}[/tex] = 121

[tex]x^{2}[/tex] + [tex]2^{2}[/tex] + 2(x) (2) = 121

[tex]x^{2}[/tex] + 4 + 4x = 121

[tex]x^{2}[/tex]  + 4x -117 = 0

[tex]x^{2}[/tex]  + 13x - 9x -171 = 0

x( x+13) -9 (x+13) = 0

(x+13)(x-19) =0

This means

x = 9, -13

Since, dimension can't be negative. So, the measure of dimension would be 9 inches by 9 inches

Answer:

A = 147

Step-by-step explanation:

A + 25 = 172

subtract 25 from both sides

A + 25 - 25 = 172 - 25

A = 147

The value of AG is 37cm

From the diagram shown, we have that;

But;

AG + GB = AB

Let's substitute the values

3x + 3 + 11x + 6 = 166

collect like terms

3x + 11x + 9 = 166

14x = 166 - 9

14x = 157

Make 'x' the subject

x = 157/ 14

x = 11. 2cm

But line AG = 3x + 3 = 3 ( 11. 2) + 3 = 33. 6 + 3 = 37cm

Thus, the value of AG is 37cm

Here,

Joan paint the porch in 5 hours.

Jan can take 4 hours to paint the porch.

We have to find the time to take them working together.

What is Fraction?

A fraction simply tells us how many parts of a whole we have.

Now,

Let x is number of hours to take them working together.

Then, 1/x is how much of the porch they can paint together in 1 hour.

Joan paint the porch in 5 hours.

Then, Joan can take 1 hour to paint the 1/5 part of porch.

Jan can take 4 hours to paint the porch.

Then, Jan can take 1 hour to paint the 1/4 part of porch.

To find how much of the porch they can paint together in 1 hour, we can add together;

[tex]\frac{1}{5}+ \frac{1}{4} = \frac{1}{x} \\\\\frac{4+5}{20} = \frac{1}{x} \\\\\frac{9}{20} = \frac{1}{x}\\\\x = 20.22[/tex]

Answer:

d. number line from -20 to 20. start at -20. count up by 5. 3 arrows are shown above the number line. 1st from 0 to 20, 2nd from 20 to 10 and 3rd from 10 to -15.

Step-by-step explanation:

The number line given run from -20 to +20 and so we record Niki's losses and wins using the negative numbers and positive numbers respectively. If Niki wins(scores 20 points) we add, that is a positive number on the number line. If Niki loses(loses 10 and 25 points) we subtract from her positive number using the negative values(points missed) on the number line. If we do this, Niki's value on the number line ends up at -15

To get Niki's final score, we calculate hence

+20-10-25 = -15 points

Giving the following information:

The price of silver has increased by 25% per year from 2000. In the year 2000, Harry bought a silver bowl for $170.

To calculate the price of the silver bowl after x years, we need to use the following formula:

F(x)= PV*(1+g)^x

F(x)= future value

PV= present value

g= growth rate

x= number of years

For example, we determine the value of the coin after 10 years:

F(x)= 170*(1.25^10)

F(x)= $1,583.25

F(x)= 170*(1.25^10)
