Answer:

BC = 39

Step-by-step explanation:

Given:

DC = 5x - 18,

BC = 3x - 6,

AB = 2x + 12

Opposite sides of a parallelogram are equal.

Therefore:

AB = DC

2x + 12 = 5x - 18

Collect like terms

12 + 18 = 5x - 3x

30 = 2x

Divide both sides by 2

15 = x

x = 15

BC = 3x - 6

Plug in the value of x

BC = 3(15) - 6 = 45 - 6

BC = 39

Answer:

Grams per cubic meter or g/cm3

Step-by-step explanation:

The answers vary, but they have the same format which is

density = mass/volume

For instance, if the mass is in grams and the volume is in cubic centimeters, then the density would be in grams/cm^3, where "cm^3" is the abbreviation of "cubic centimeters". We can read "grams/cm^3" out as "grams per cubic centimeter"

Answer:

92

Step-by-step explanation:

8* x + y + y

Where

x=9, and y = 10​

Solution=8×9+10+10

=72+20

=92.

So the answer is 92

x=-4

Step-by-step explanation:

brainliest please

Answer:

x=-4, Give brainliest please

Step-by-step explanation:

Step 1: Add 8.4x to both sides.

2.1x+45.2 =  -8.4x +3.2

       +8.4x    +8.4x

10.5x+45.2=3.2

Step 2: Subtract 45.2 from both sides.

10.5x + 45.2 = 3.2

         -45.2    -45.2

10.5x=−42

Step 3: Divide both sides by 10.5.

[tex]\frac{10.5x}{10\\}[/tex]=[tex]\frac{-42}{10}[/tex]

x=−4

Answer: -4.5 ℉

Step-by-step explanation:

Given: On the coldest day of the year, the temperature at noon = 11℉

By midnight, the temperature had decreased by 15.5℉.

i.e. The temperature at midnight = Temperature at noon - 15.5℉

= 11℉ - 15.5℉

= (11-15) ℉

= -4.5 ℉

Hence, the temperature at midnight was -4.5 ℉.

Answer: x=3

y=4

Step-by-step explanation:

since both equations equal y then  you can  just make them equal

so 3x-5=-2x+10

3x=-2x+15

5x=15

x=3

y=3(3)-5

y=9-5

y=4

Step-by-step explanation:

The triangle being 180,

Answer:

[tex]m<1+m<2+m<3=180[/tex]

Step-by-step explanation:

The way I remember it is that an equilateral triangle has all three angles that are 60° and 60+60+60 = 180 so it is [tex]m<1+m<2+m<3=180[/tex].

Answer:

15.8 feet

Step-by-step explanation:

Stacy is making a shelf to store her books

She is using 5 pieces of wood

Each wood is 3.16 feet long

Therefore the total feet of the wood that Stacy will use to make the shelf cab me calculated as follows

= 3.16 ×5

= 15.8 feet

Answer: by doing the input and the output usually that means add a number or any other mathematical equations.

Step-by-step explanation:

Given :

C) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm.

There exist two circles of center A and tangent to (C).

To Find :

The radius of the new circles.

Solution :

Since, OA is 3 cm .

So, first circle with tangent to C if centre is at A is OA itself.

First radius, r = 3 cm.

And second circle is the on with radius , R = 3 + 2 = 5 cm.

Therefore, the radius of both the circles are 3 cm and 5 cm.

Hence, this is the required solution.

Answer:

-2k

Step-by-step explanation:

Answer:

5

To find:

k

Step-by-step explanation:

-5 (3 + 4k) = -115

-5 × 3 + -5 × 4k = -115

-15 - 20k = -115

-20k = -115 + 15

-20k = -100

k = -100/-20

k = 5

Answer:

So the slope on a scatterplot is almost always an estimate, so its not exact. It is just an estimate on where it might go and what might happen t data in the future.

Answer:

The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
