Please HELP im so confused
3x-8y=7
2y+16x=15

Answer:

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Using distributive property:

A : -30(3+2w)  =  -90 - 60w          : equivalent to -90 - 60w

B : (-9-6w) ⋅ 10  = -90 - 60w          : equivalent to -90 - 60w

C : -3(30 - 20w)  = -90 + 60w       : NOT equivalent to -90 - 60w

D : (6 + 4w)×15  = 90 + 60w          : NOT equivalent to -90 - 60w

E : −20(4.5 + 3w) = - 90 - 60w     : equivalent to -90 - 60w

SO THAT MEANS

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Step-by-step explanation:

Answer:

3x + x = 48

12 pages

Step-by-step explanation:

let the number of pages read by Joelle be represented by x

Joelle = x pages

Deirdre = 3x (since she reads 3 times as much pages as Joelle)

3x + x = 48

4x = 48

x = 12 pages

So Joelle reads 12 pages

Answer:

x = 12

Step-by-step explanation:

12x - 4 = 10x - 10 + 30

12x - 4 = 10x + 20

12x - 10x = 20 + 4

2x = 24

x = 12

Answer:

Triangle WRD's angles are all 60 degrees, angle W and angle R and angle D.

Triangle WRD is an equiangular, equilateral triangle. It is also an acute triangle, as all angles are less than 90 degrees.

Step-by-step explanation:

You are told that WRD has all equal sides, each 3 inches long.

In a triangle, if sides are equal, then the opposite angles are also equal. So if ALL the sides are equal, then ALL the angles are equal.

The sum of the interior angles in a triangle is always 180 degrees. Since the trhee angles are all equal and they must add up to 180 degrees, 180/3 =60, so the angles must all be 60 degrees.

Triangle are classified by sides as

*** scalene = no equal sides

*** isosceles = two equal sides

*** equilateral = all equal sides

Triangles are classified by angles as

*** right triangle = one 90 degree angle

*** obtuse triangle = one angle larger than 90 degrees

*** acute triangle  = all angles less than 90 degrees

*** equiangular = all angles equal

There can be overlap in the categories, like an acute triangle also being equiangular.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Translation is the movement of a point up, down, left or right. Translation is a rigid transformation, that is it preserves the shape and size of the figure. Types of rigid transformation are rotation, reflection, and  translation.

If the distance between Line segment AB and line segment XY is 2 units and then both line segments are  translated 2 units left and 3 units down to form line segments A'B' and X'Y'. The distance between the newly formed line segments A'B' and X'Y' would still be 2 units.

Step-by-step explanation:

Given:

In ΔJKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°.

To find:

The value of  ∠K to the nearest 10th of a degree.

Solution:

According to the Law of Sine:

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

We have, In ΔJKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°.

Using the Law of Sine, we get

[tex]\dfrac{j}{\sin J}=\dfrac{k}{\sin K}[/tex]

[tex]\dfrac{3.8}{\sin (63^\circ)}=\dfrac{4.1}{\sin K}[/tex]

[tex]3.8\sin K=4.1\sin (63^\circ)[/tex]

[tex]\sin K=\dfrac{4.1\sin (63^\circ)}{3.8}[/tex]

[tex]\sin K=0.961349[/tex]

[tex]K=\sin^{-1}(0.961349)[/tex]

[tex]K=74.0182[/tex]

[tex]K\approx 74.0[/tex]

Therefore, the measure of angle K is 74.0 degrees.

The height, width and Lenght isn't Given. However, we can create an hypothetical scenario, with a height 6, length 8 and width 4

Answer:

192 unit³

Step-by-step explanation:

The volume of the card box :

Recall the volume of box formula :

V = length * width * height

Volume = 8 * 6 * 4

Volume = 192 unit³

This is the procedure for any given dimension of the card deck.

144+48= 192

There has been sold 12 items of f and 36 items of e in the system.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We are Given the system of equation:

(1) e + f = 48

(2) e = 3f

Then Substituting e=3f into e + f=48:

3f + f = 48

Adding similar terms:

4f = 48

Dividing both sides by 4:

f = 48/4

Simplifying:

f = 12

Replacing;

f=12 in e + f =48

e + 12 = 48

Now Subtracting -12 to both sides:

e = 48 - 12

e = 36

Thus There has been sold 12 items of f and 36 items of e.
