Answer:

x = -24

Step-by-step explanation:

If you are to solve for x then multiply everything by 2 so

[tex]\frac{2x}{8}[/tex] - 1 = -7 now multiply everything by 8 to get rid of the fraction

2x - 8 = -56, solve for x so 2x = -48 so x = -24

Answer: 2

Step-by-step explanation: Add −3 and 5

Answer:

The total surface area of the figure is 516 square units.

Step-by-step explanation:

The net of the triangular prisms is attached. Remember, the total surface area refers to the area of each face of the volumetric figure. In this case we have 3 equal rectangles and 2 equal triangles.

   2. The Area of the triangles.

The total surface area is given by the sum of all these areas:

S= 420 + 96 = 516 u^2.

Answer:

I did learn this before I'm not sure, but I think the answer is X x 10 = Y because on the chart for example X= 1 and Y= 10 so whatever number is on Y is basically X multiplied by 10. I hope this helps!

Answer:

$$$$4.17

Step-by-step explanation:

20-13.83=6,17

6.17-2=4.17

Answer:

$4.17

Step-by-step explanation:

$13.83+ tip ($2.00)=$15.83

$20.00-$15.83=$4.17

Answer:

All below

Step-by-step explanation:

1. Before tax

500*0.7 (30% off means 100%-30% of the price = 70% or 0.7) = $350

2. Final selling price

350*1.13 (100%+13% as the price after adding 13% of tax to subtotal) = $395.5

Answer: BC = 54  <kjm=44

Step-by-step explanation:

1st 0ne-

if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)

so

6x=9x-27  (by corresponding parts of congruent Theorem)

-3x=-27

x=9

BC- 9(9)-27= 81-27=54

2nd one-

J bisects KJM

4x+6=3x+10

x=4

3(4)+10= 22

4(4)+6= 22

KJM= 22+22= 44

Answer:

Step-by-step explanation:

BD is the perpendicular disector of isosceles triangle DAC

AB=BC

6x=9x-27

3x=27

x=9

BC=9x-27=54

For triangle JKL and JML,

KL=ML

JL=JL

JK=JM from properties of right-angled triangle

So triangle JKL and JML are congruent

<KJL = <MJL

4x+6=3x+10

x=4

<KJL=4*4+6=22

sorry if im wrong

Answer:

y =  1/2x + 4 1/2

Step-by-step explanation:

(9 , 9) (3 , 6)

slope (m) = Rise (Δy) /run (Δx) = (9-6) / (9-3) = 3/6 = 1/2

(y-6)/(x-3) = 1/2

y-6 = 1/2 (x-3) = 1/2x - 3/2

y = 1/2x + 9/2 = 1/2x + 4 1/2

Hi, you've asked an incomplete question. However, I provided a brief explanation about surface areas.

Explanation:

Surface area is a term commonly used in mathematics, and other branches of science, and it basically refers to a calculation of the total space that an object occupies.

For example, you can find the surface areas of a cuboid using the formula:

[tex]6s^{2}[/tex] where s= side length.

C. 1/6 becuase there are six numbers you could possibly land on and it is facing one side up.

Answer:

[tex](4x-1)^2[/tex]

Step-by-step explanation:

Area of a square = [tex]l^2[/tex]

If l = [tex](4x - 1)[/tex],

Then area = [tex](4x - 1)^2[/tex]

Answer:

y is 8

Step-by-step explanation:

First u do 13y-9y=4y

so you then have 4y-5=27

then you plus 5 to 27

u then have 4y=32

then divide 32 by 4

so you will get y=8

Step-by-step explanation:

First graph a point at (0, 20) since that is the y-intercept. Then, at (1, 35) then at (2, 50) and draw a line connecting all three points. We graph them at these points because we know that for every month, we spend $15, so we go up by intervals of 15 for every month.

Answer:

15, 30, 60, 120, 240, 480.

Step-by-step explanation:

You multiply the numbers by 2 to get to the next number.

For example, 15*2 is 30. 30*2 is 60. 60*2 is 120, etc..

Answer:

480

Step-by-step explanation:

In order to find the answer to this question you need to find the rule to the sequence and then add in till you get to the 6th term.

[tex]15,30,60[/tex]

Rule = each term doubles as it goes to the next term

[tex]15,30,60,120,240,480[/tex]

[tex]=480[/tex]

Answer:

A= 5278.34 in ²

Step-by-step explanation:

A= r² × 3.14 (pi)

Radius = Diameter ÷ 2

82 ÷ 2 = 41
