Answer:

Sally has $10.25 or 1,025 pennies

Step-by-step explanation:

Answer: x=1

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3*x+2*(5*x-3)-(7)=0

3x + 2 • (5x - 3)) - 7 = 0

Pull out like factors :

13x - 13 = 13 • (x - 1)

13 = 0

A a non-zero constant never equals zero.

Solve : x-1 = 0

Add 1 to both sides of the equation :

x = 1

Given:

Two triangles are congruent, i.e., [tex]\Delta ABC\cong \Delta XYZ[/tex].

To find:

All the measures of both triangle.

Solution:

We have,

[tex]\Delta ABC\cong \Delta XYZ[/tex].

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

[tex]\angle A=\angle X[/tex]

[tex]\angle B=\angle Y=90^\circ[/tex]

[tex]\angle C=\angle Z=37^\circ[/tex]

It triangle ABC,

[tex]\angle A+\angle B+\angle C=180^\circ[/tex]     (Angle sum property)

[tex]\angle A+90^\circ+37^\circ=180^\circ[/tex]

[tex]\angle A+127^\circ=180^\circ[/tex]

[tex]\angle A=180^\circ -127^\circ[/tex]

[tex]\angle A=53^\circ[/tex]

So,

[tex]\angle A=\angle C=53^\circ[/tex]

[tex]AB=XY=3\text{ units}[/tex]

[tex]BC=YZ=4\text{ units}[/tex]

[tex]AC=XZ=5\text{ units}[/tex]

Therefore, m∠A = 53˚,  m∠B =90˚ , m∠C =37˚ , m∠X = 53˚,  m∠Y =90˚ , m∠Z =37˚ , Segment AB = 3 units , Segment BC = 4 units , Segment AC = 5 units , Segment XY = 3 units , Segment YZ = 4 units , Segment XZ = 5 units .

Answer:

68.7 - t

Step-by-step explanation:

Here, we are interested in giving the expression that Kalinda can use to know the difference in height between her and Terrence

From the question, Kalinda is 68.7 inches tall while Terrence is t inches tall

To know the difference in their heights, we simply subtract Terrence’s height from Kalinda’a

Mathematically, that would be 68.7 - t

Given parameter:

Diameter of the ferris wheel  = 80m

Unknown:

Distance covered in one complete rotation = ?

Solution:

One complete rotation will sweep through the circumference of the wheel.

So,

  One complete rotation = Circumference of circle  = 2 [tex]\pi[/tex] r

Where r is the radius;

         Radius here is [tex]\frac{80}{2}[/tex]  = 40m

So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]

The distance the wheel sweeps through will be 80π m

Answer:

Ep = weight x height = 5 x 1 = 5N ; 5 x 1.5 = 7.5N; 5 x 2 = 10N

Answer:

n = 250

Step-by-step explanation:

-17 + [tex]\frac{n}{5}[/tex] = 33

[tex]\frac{n}{5}[/tex] = 33 +17

[tex]\frac{n}{5}[/tex] = 50

([tex]\frac{5}{1}[/tex]) ([tex]\frac{n}{5}[/tex]) = 50 *(5)

n = 250

check: -17 + [tex]\frac{250}{5}[/tex] = 33

-17 + 50 = 33

33 = 33

Answer:

i just did this in class a week ago and i think it was option c

Step-by-step explanation:

Answer:

1 = 137

2 = 43

3 = 43

4 = 137

Step-by-step explanation:

for the first line, do (180-137 = 43)

then, 43 would be corresponding angle to 2 - making them equal

2 would be vertically opposite to 3, making them equal

137 and 1 are corresponding- making them equal

4 is vertically opposite to 1 - making them equal

Answer:

D

Step-by-step explanation:

The constant of proportionality is 8 as seen by the equation:

y = 8x

8 will constantly be multiplied by x (the number of dollars earned) to solve for y (number of tickets sold)

The number 8 will not change

Therefore, 8 is the constant ot proportionality

Answer:

y= -1/2x + 2

or y = -0.5x + 2

Step-by-step explanation:

Use the slope formula to get the slope:

(y2-y1)/ (x2-x1)

(2-0)/(0-4)

2/-4

-1/2

Plug in any point in Point-Slope Formula:

y - y1 = m(x-x1)

y- 0 = -1/2 (x -4)

y = -x/2 + 4/2

y= -1/2x + 2

Answer:

It is

-0.5(3x+5)= -1.5x+2.5

Step-by-step explanation:

-0.5(3x+5)

multiply-0.5 with 3x and 5 to get rid of the brackets.

-0.5×3x= -1.5x

-0.5×5= 2.5

-1.5x+2.5

Answer:

Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

Step-by-step explanation:

La X: En matemáticas la x hace referencia a una incógnita o variable. Variable quiere decir que puede tomar un valor específico dentro de conjunto. Por ejemplo, si tenemos "X+1=3" con X que pertenece al conjunto de los números enteros, la X toma el valor exacto de 2 del conjunto de los enteros.

Answer:

The length of one side is 13 feet.

Step-by-step explanation:

To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:

[tex]2x+5=6x-11[/tex]

In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:

[tex]5=4x-11[/tex]

After that, you solve it like a normal one-step equation. Add 11 to both sides.

[tex]16=4x[/tex]

Now, divide both sides by 4 and you will know how much [tex]x[/tex] is worth.

[tex]4=x[/tex]

Now that we know how much [tex]x[/tex] is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.

[tex]2(4)+5[/tex]

That would give us 13.

Answer:

the sides are 13

x= 4

Step-by-step explanation:

2x+5 = 6x-11     subtract five from both sides

2x = 6x-16        subtract 6x from both sides

-4x = -16           divide both sides by -4

x = 4                substitute into original problem

2(4) + 5 = 6(4) - 11

8 + 5 = 24 - 11

13 = 13
