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

Step-by-step explanation:

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: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

=1×2/2×2 + 1/4

=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:

[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]

Answer:

X=20 3x=60

Step-by-step explanation:

a straight line is 180

180-100=80

4x=80

x=20

We can create a equation to solve for x here.

We will use the following equation:

How to solve it step-by-step

[tex]100 + 3x + x = 180\\\\100 + 4x = 180\\\\4x = 80\\\\x = 20[/tex]

10)  got wrong picked never true

11) two points I only got 1 I picked you overdrew on the account by 36.00 so I guess the other is the acount has a balance less than

Step-by-step explanation:

In this we have to isolate x. So for this firstly we will multiply both side of equation by 2.

Now we can add 2 in both side

1/6 = 0.16 acres in 8 minutes.

--

0.16  ÷ 8 = 0.02 acres mowed in 1 minute.

--

(60 minutes in an hour)

0.02 x 60 = 1.2 acres mowed in an hour.

--

1.2 is equal to 1 1/5, and jami needs to mow 1 1/2 acres. so no, jami cannot mow 1 1/2 acres in an hour.

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
