What is the solution to this equation?
6x + 10 - 2x=7+23
A = 2
B. 5
C. x=15
D. x4

Answer:

C = (1, 14 )

Step-by-step explanation:

The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.

Find the average of endpoints and equate to coordinates of midpoint

A (5, - 2 ) , let C = (x, y ) , then

[tex]\frac{x+5}{2}[/tex] = 3 ( multiply both sides by 2 )

x + 5 = 6 ( subtract 5 from both sides )

x = 1

and

[tex]\frac{y-2}{2}[/tex] = 6 ( multiply both sides by 2 )

y - 2 = 12 ( add 2 to both sides )

y = 14

Coordinates of C = (1, 14 )

Answer:

-5

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 4 - -1)/( 9 - 10)

    ( 4+1)/( 9-10)

    5/ -1

   - 5

Explanation:

First we need to find the volume of the cube

volume = length*width*height = 4*4*4 = 64 cubic cm

Then we'll divide the mass over this volume to get the density

density = mass/volume

density = (12 grams)/(64 cm^3)

density = (12/64) grams per cm^3

density = 0.1875 grams per cm^3

The notation cm^3 is another way of saying "cubic centimeter" as shorthand.

Answer:

i think the answer is 1 1/8 (or 1.125)

Step-by-step explanation:

1. -3/8 / -1/3 = 3/8 * 3/1 = 9/8

2.Simply this improper fraction to a mix number

9/8 = 1 1/8 (and since 1 is going into the 9,8 it cannot be reduced further)

3rd 1 1/8 is recognized as 1.125

Step-by-step explanation:

Distance = √(x_2 - x_1)² + (y_2 - y_1)²

Distance = √[(-a) - a]² + (b - b)²

Distance = √[-2a]² + (0)²

Distance = √4a²

Distance = 2a

An compound inequality that describes the acceptable weights for a 20 oz box is 19.25 ≤ x ≤ 20.75.

The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To determine the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.

We are Given that, cereal manufacturer has a tolerance of 0.75 oz for a box of cereal that is supposed to weigh 20 oz.

Let the weight of cereal box be; w

Now, the inequality is

20-0.75 ≤ x ≤ 20+0.75

Add 20 on both sides of an inequality, we get

19.25 ≤ x ≤ 20.75

Here, 19.25 ≤ x ≤ 20.75

Therefore, an absolute value inequality to find the range of acceptable weights is 19.25 ≤ x ≤ 20.75.

Answer:

∠4

Step-by-step explanation:

Since the opposite of ∠2 is ∠4, then the vertical angle of ∠2 would be ∠4. (That is the literal definition of vertical angles)

Answer:

70% of the members voted for Jina.

Step-by-step explanation:

votes : members

  28   :      40

  70   :      100

70% of the members voted for Jina.

Answer:

70%

Step-by-step explanation:

To find the percentage, turn 28/40 into a fraction:

28

------------

40

Then, keep simplifying it, or dividing it by the GCF.

28 14 7

------------ ----> ----------- ----> -----------

40 20 10

7/10 in a percentage is 70 percent since 7/10 can turn into 70/100

Answer:

No

Step-by-step explanation:

Answer:

x=73, y=107, z=73

Step-by-step explanation:

Each horizontal should equal 180 therefore x would be 180-107 and so on.

[tex]5(2x-3)=-4(x+4)-13\\\\10x-15=-4x-16-13\\\\10x+4x=-16-13+15\\\\14x=-14 \ \ /:14\\\\\huge\boxed{x=-1}[/tex]

Answer:

x = -1

Step-by-step explanation:

5(2x – 3) = -4(x + 4) – 13

Use distributive property,

5*2x - 5*3 = -4*x +(-4)*4 -13

10x -  15    = -4x - 16 - 13

10x - 15    = -4x - 29

Add 15 to both sides

10x  = -4x  -29 + 15

10x = -4x - 14

Add 4x to both sides

10x + 4x = -14

       14x = -14

Divide both sides by 14

x = -14/14

x = -1

Answer:

y = 3x - 7

Step-by-step explanation:

Use the slope intercept formula [ y = mx + b ], the slope, and the point given to find the y-intercept.

-1 = 3(2) + b

-1 = 6 + b

-7 = b

Now input the values we solved for and what we are given back into the formula.

y = 3x - 7

Answer:

ok the answer is wrong because

when you multiply them you get

-25y^2 + 50y -21

because 5y*-5y is -25y^2 not 21y^2

Step-by-step explanation:

15 x 64 = 15 x (60 + 4)

= (15x60) + (15x4)
