ANSWER ONE AND TWO ILL GIVE YOU BRAINLIST!!!

Answer:

3x - 12 = -15

x = -1

Step-by-step explanation:

3x - 12 = -15

3x = -3

x = -1

Answer:

x = -1/2

Step-by-step explanation:

50x + 54 = 34x + 46

Subtract 34x from each side

50x-34x + 54 = 34x-34x + 46

16x +54 = 46

Subtract 54 from each side

16x+54-54 = 46-54

16x = -8

Divide by 16

16x/16 = -8/16

x = -1/2

Answer:

[tex]x=-\frac{1}{2}[/tex]

Step-by-step explanation:

So we are given an equation and we are asked to solve for x.

50x + 54 = 34x + 46

Subtract 54 from both sides.

50x = 34x - 8

Subtract 34x from both sides.

16x = -8

Divide both sides by 16.

[tex]x=-\frac{1}{2}[/tex]

So now we have solved for x. We have found that [tex]x=-\frac{1}{2}[/tex].

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

79

Step-by-step explanation:

m<1 = 90 -38 = 52

m<3 = 90 - 52 = 38\

m<2 = 180-38-63 = 79

Answer:

Step-by-step explanation:

<1 + <3 = 90                 Parallel lines produce interior angles that add to to 90

<1 + 38 = 90                 Substitution

<1 = 90 - 38                  52

<3 = 90 - 52

<3 = 38

38 + 63 + <2 = 180      Sum of angles in a triangle always = 180

101 + <2 = 180

<2 = 79

Step-by-step explanation:

Answer:

1 71/72

Step-by-step explanation:

1 7/8 + 1/9 = 1 + 7/8 * 9/9 + 1/9 * 8/8 = 1 + 63/72 + 8/72 = 1 + 71/72 = 1 71/72

Answer:

a=c/b-d/b

Step-by-step explanation:

Answer:

a=c-d/b

Step-by-step explanation:

We first need to isolate the variable "a" by doing the opposite operation.

1. subtract "d" on both sides

After step 1-     ab=c-d

2. divide both sides by "b" because that is the only way to isolate a permanently

After step 2-     a=c-d/b

Answer:

(x + 10, y + 0)

Step-by-step explanation:

in the graph, all points of the triangle (a, b, and c) are translated 10 units to the right. when things are translated to the right, the x is the number being affected.

QS bisects the ^PQR^ :

So -----¢ PQS = SQR = 45°

_________________________________

PQR = PQS + SQR = 45°+ 45° = 90 °

Q^ = 90° ----¢ So the PQR triangle is a

right triangle.

Answer: y=3x-3

Step-by-step explanation: First plot your point then use the slope to plot another one and get a line. then use slope-intercept formula y=mx+b. M= slope which is 3 and B= the y-intercept.

Answer:

Bruce needs to sell 267 widgets each month to make a profit.

Step-by-step explanation:

From the information given, you can write that the cost of the monthly rent plus the cost  in labor and materials to make each widget for the number of widgets is equal to the amount of sales:

10x +4000 = 25x

Now, you can solve for x:

4000 =25x-10x

4000=15x

x= 266.67→267

According to this, the answer is that Bruce needs to sell 267 widgets each month to make a profit.

Answer:

75feet

Step-by-step explanation:

To measure a stone face carved on the side of a​ mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 ​, what is the height of the stone​ face?

Iet us say we have two right triangles. With a base of 700. The first has angle of 35o and the other has an angle of 38degree

Then we need the Height

From trigonometry

Tan = opposite/adjacent.

In this case the adjacent is 800

Tan 35 = 0.7002

Tan 38 = 0.781

Answer:

The answer is B

Step-by-step explanation:

This is because when you distribute the -4 to 9^6 and 7^-24 you will get 9^-24 and 7^36. Then, you can move the 7^-24 to the denominator because of the negative exponent rule.

Answer:

E.

Step-by-step explanation:

Translation: slide of the shape or figure, it does NOT change its shape, size, and form, count how many units the shape moves.

Reflection: flip of the shape, does NOT change its shape, size, and form, either can be flipped or reflected over the x or y axis.

Rotation: turn of the shape, does NOT change its shape, size, and form, either can be rotated counter clock wise left, (opposite of a clock direction), or clockwise, the direction a clock moves right. It can also be rotated 90° (1 turn), 180° (2 turns), 270° (3 turns) or 360° (4 turns). In highschool, you will get introduced to more degrees of rotation, this is just middle school level.

Answer:

≈ 10.6 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = p(3, - 1) and (x₂, y₂ ) = q(- 5, 6)

d = [tex]\sqrt{(-5-3)^2+(6+1)^2}[/tex]

   = [tex]\sqrt{(-8)^2+ 7^2}[/tex]

    = [tex]\sqrt{64+49}[/tex]

     = [tex]\sqrt{113}[/tex] ≈ 10.6 ( to 1 dec. place )

Answer:

  D. [tex]y=\begin{cases}-2&x<-3\\4&x>-3\end{cases}[/tex]

Step-by-step explanation:

C.  The line to the left of x=0 has a slope of -1 and a y-intercept of 2. That portion of the function does not include x=0. The line to the right of x=0 has a slope of -3 and a y-intercept of 5. That portion of the function includes the case x=0.

Answer:

Step-by-step explanation:

Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

Answer:
