Answer:

2x=50

Step-by-step explanation:

Hi there,

Your question is "twice a number (x) is fifty"

Recall how a number is represented by x.

Twice a number would be represented as 2x.

Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]

If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.

Notice how 2 is multiplying the x.

To isolate x, divide that side by 2.

However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.

[tex]2x=50[/tex]

[tex]\frac{2x}{2} = \frac{50}{2}[/tex]

[tex]x=25[/tex]

Equation: [tex]2x=50[/tex]

Solving for x: 25

Hope that helps!

Answer:

she needs 3 1/3 more yards

Step-by-step explanation:

There are 3 feet in a yard

14yards x 3feet = 42 feet

58 feet- 42 feet= 10 feet

10 divded by 3 is about 3.3

Answer: 6 yards

Step-by-step explanation:

1)    14 x 3 = 42

2)    58 - 42 = 16

3)    16 / 3 = 5.33333333....

4)     round up = 6

d = 120

Answer: TUY: 120°

Step-by-step explanation:

Hello,

1. Recall that the sum of a triangle’s angles is 180°, regardless of the type of triangle.

2. Find TUS, that is, the angle for U.

U = 180°-(50°+70°)=60°

For TUY:

Knowing that U=60° and that the line above U is 180°:

180°-60°=120°

Answer:

12y-2xy

x=5, y=10

(12x10) -(2x5x10)

=120-100

=20

Step-by-step explanation:

1.first collect the information you have been given in the question to make answering of the question easy.

2.then substitute the x value (in this case 5) and the y value (10) into the expression 12y - 2xy on there respectful positions.

3.having done so, you can then multiply and thereafter subtract as the question requires you to do.

Note: only substitute the y and x values where y and x appear in the question.

Always start with multiplying, after substituting,before subtracting or adding.

Just kidding.

now help me for 100 points.

Answer:

The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Answer:

x=1/3

y=-7

Step-by-step explanation:

using the elimination method, you can add both equations vertically, to eliminate the x

-3x+y=-8

3x+2y=-13

3y=-21

y=-7

we then fix the value of y into the first equation

-3x+y=-8

-3x-7=-8

-3x=-8+7

-3x=-1

x=1/3

Answer:

area of triangle=1/2 (base×height)=1/2 (7×11)=38.5cm²

Answer:

2. -8x - 6

3. 4.5x + 10 (I think, not quite sure)

4. 0.25 - 5x (I think, also not quite sure)

5. -8x - 5y + 5.5

Step-by-step explanation:

2. Distribute the -2 to all terms except -1.

-2(4x + 2.5) - 1

-8x - 5 -1

-8x - 6

5. Combine 6x and -14x (6 - 14 = -8).

6x - 5y - 14x + 5.5

-8x - 5y + 5.5

Answer:

42

Step-by-step explanation:

So you basically replace the x with 2. So f(x) = x21, then it would change to f(2) = 2(21). Then you would just multiply 21 by 2 and you would get 42.

Hope this helps!

The answer is 14

Answer:

a) Braxton's initial investment is equals to (=) Pam's initial investment.

b)The interest on Braxton's account is less than (< ) the interest on Pam's

   account.  

Step-by-step explanation:

Given - Braxton has money in a savings account. The equation

            B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money    

            in dollars, B, Braxton has in his account after t years since opening

             the account.  Pam also has money in a savings account. The  

            equation, P= [tex]800(1 + 0.04)^{t}[/tex]  can be used to calculate the  amount of  

             money in dollars, P, Pam has in her account after t years since  

              opening the account.      

To find - a) Braxton's initial investment ..........Pam's initial investment.

                b) The interest on Braxton's account .....the interest on Pam's

                    account.

Proof -

As given, Broxton equation is -  

                 Pam equation is -    

Now,

a.)

For initial investment , Put t = 0

⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]  

   P =  [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]  

We can see that for  t = 0

Initial investment of Braxton = Initial investment of Pam

⇒Braxton's Initial investment = Pam's initial investment.

b.)

For the interest,

As we have not given any time period for which the interest has to be find.  

So , let the time period , t = 5 years

Therefore,

B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.159) = 927.42[/tex]  

P = [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.217) = 973.32[/tex]

Now,

Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127

Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173

∴ we get

The interest on Braxton's account is less than the interest on Pam's account.
