Answer:12 lessons

Steps in image below:

The number of lessons that take for the cost to be the same with and without a membership will be 12.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The equation is given below.

186 + 10x = 25.5x

Simplify the equation, then we have

25.5x - 10x = 186

15.5x = 186

x = 186 / 15.5

x = 12

The number of lessons that take for the cost to be the same with and without a membership will be 12.

Answer:

The profit is 1.75x-0.5

Step-by-step explanation:

Mathematically,

profit = sales - cost

So with respect to this case, we have that;

Profit = s(x) - c(x)

Profit = 2x - (0.25x + 0.5)

Profit = 2x - 0.25x -0.5

Profit = 1.75x - 0.5

Answer:

I think of a number and multiply it by three, when I add it with 129 my answer will be equal to 1000. what is the number

Step-by-step explanation:

A slope of 0.47 means that, for every 100 feet of horizontal change, the vertical rise = 47 feet

We can use a proportion here

0.47 / 1 = 1 / x

Cross-multiply

0.47x = 1*1

0.47x = 1

Divide both sides by 0.47

x = about 2.13 units

=2/4+1/4

=3/4

Answer:

B) 1/4 because if the pizzas have 8 slices then 1/4=2 slices and 1/2=4 slices    4-2=2 and 2 slices equal 1/4 of the pizza.

Answer:

1500+337.50 = $1,837.5

Step-by-step explanation:

You want to calculate the interest on $1500 at 4.5% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

I = P x r x t

Where:

P is the principal amount, $1500.00.

r is the interest rate, 4.5% per year, or in decimal form, 4.5/100=0.045.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1500 × 0.045 × 5 to get that:

The interest is: $337.50

Answer:

t = 4

Step-by-step explanation:

1. 2*t = 2t

2. 2*1 = 2

3. 2t+2 = 10

4. 10-2 = 8

5. 2t = 8

6. 8/2 = 4

7. t = 4

Answer:

t = 4

Step-by-step explanation:

2(t + 1) = 10

2t + 2 = 10

2t = 10 - 2

2t = 8

t = 8 ÷ 2

t = 4

Answer:

y  = 0.70x-  10.00

Step-by-step explanation:

--  Since one friend gave you 10.00 ,subtractthis from the 13.50 to give you the amount earned by walking the 5 miles

--  13.5-10.00  =  $3.50  

--  Since you walked 5 miles, divide by 5 to give you 0.70 per mile earned.

So, an equation that represents the amount of money earned is:  

y  = 0.70x-  10.00  . This is in slope-intercept form; the slope is $0.70 and represents the amount of money earned per mile  and the intercept is $10.00 and represents the initial amount of money that you were given.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

Answer:

[tex]x =3[/tex] or [tex]x = 7[/tex]

Step-by-step explanation:

Given

[tex]x^2 - 10x = -21[/tex]

Required

Solve by factoring & quadratic formula

By Factoring:

[tex]x^2 - 10x = -21[/tex]

Equate to 0

[tex]x^2 - 10x +21 = 0[/tex]

Expand:

[tex]x^2 - 7x -3x+21 = 0[/tex]

Factorize:

[tex]x(x-7)-3(x-7) = 0[/tex]

[tex](x-3)(x-7) = 0[/tex]

[tex]x -3 = 0[/tex] or [tex]x - 7 = 0[/tex]

[tex]x =3[/tex] or [tex]x = 7[/tex]

By quadratic

[tex]x^2 - 10x = -21[/tex]

Equate to 0

[tex]x^2 - 10x +21 = 0[/tex]

For

[tex]ax^2 + bx + c = 0[/tex]

x is solved using:

[tex]x = \frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

where

[tex]a = 1[/tex]; [tex]b = -10[/tex]; [tex]c = 21[/tex]

So:

[tex]x = \frac{-(-10)\±\sqrt{(-10)^2-4*1*21}}{2*1}[/tex]

[tex]x = \frac{10\±\sqrt{100-84}}{2}[/tex]

[tex]x = \frac{10\±\sqrt{16}}{2}[/tex]

[tex]x = \frac{10\±4}{2}[/tex]

Split

[tex]x = \frac{10+4}{2}[/tex] or [tex]x = \frac{10-4}{2}[/tex]

[tex]x = \frac{14}{2}[/tex] or [tex]x = \frac{6}{2}[/tex]

[tex]x = 7[/tex] or [tex]x =3[/tex]
