The integers are 24,26,28. even numbers are taken as 2x and then adding 2 to it for consecutive even integers.

Answer:

Let x = the smallest even integer, x + 2 = the next even integer, and x + 4 = the largest even integer.

Write the equation x + x + 2 + x + 4 = –78.

Simplify the equation as 3x + 6 = –78.

Solve the equation by subtracting 6 and dividing by 3 on both sides of the equation.

Check that the sum of the integers –28,

–26, and –24 is –78.

Graph the linear equation. Find three points that solve the equation, then plot on the graph. -3y=x-6
nata0808 [166]

Answer:

Step-by-step explanation:                               x - 6

The given equation can be re-written as y = ---------                              

                                                                             -3

Arbitrarily choose x = 0.  Then:

      x - 6         0-6

y = --------- = ----------- = 2, so (0, 2) is a point on the graph which is also the                              

          -3            -3                                                                  y-intercept

Arbitrarily choose x = 6.  Then y = 0, and (6, 0) is another point on the graph                                    

                                                              which happens to be the x-intercept

arbitrarily choose x = 12.  Then y = (12 - 6) / (-3) = -2.  Then  (12, -2) is            

                                                                                  another point on the

                                                                                  graph.

Plot (12, -2), (6, 0) and (0, 2).  Draw a line through these three points.

What is the additive inverse of 7/2 ?<br> A) −2/7<br> B) −7/2<br> C) 2/7<br> D) 7/2
snow_lady [41]
The additive inverse of 7/2 would be -7/2 (option B) Since its. opposite !

A)is the additive inverse of C) ; C) is the additive inverse of A) (not your answer)

B. is the additive inverse for this problem (7/2) so thats how we found that this is your answer (answer)

D is the same thing for the problem (7/2) (not your answer)

7/2 isnt the additive inverse for 7/2 because they are the SAME not the opposite.

+ = - (Positive = negative)

- = + (negative = positive)

(50 POINTS AND BRAINLIEST TO BEST)
Nana76 [90]

a) Cube area = 6a^2

a = 6(5.25)^2

5.25 * 5.25 = 27.5625 * 6 = 165.375

Rounded, thats 165.38

b) Rectangular prism area = 2(wl + hl + hw)

Lets say l = 6.8, w = 8.2, h = 10

It equals about 441.52
