Which choice shows the result of substituting 3x – 5 into the second equation for y?
ahrayia [7]

Answer:  The answer is (B) 2x + 3(3x – 5) = 51 .

Step-by-step explanation:  We are given three options and we are to select which choice shows the result of substituting 3x – 5 into the second equation for y.

So, y = 3x - 5.

Since the standard form of a linear equation i two variables is ax + by = c, so the second equation as given in the options must be of the form 2x + 3y = 51.

If we substitute y = 3x - 5, then this equation becomes

2x + 3(3x - 5) = 51.

Thus, (B) 2x + 3(3x – 5) = 51  is the correct option.

The volume of a cube is 27 cubic meters. what is its surface area in square meters?
erma4kov [3.2K]

To find the answer, take the measurement of an edge of the cube, multiply it by 6, and then square that number.

Ex:

Edge = 16

Faces in 1 cube = 6

     6 * 16 = 96

96^2 (which is just 96 * 96)= 9,216


I hope this helps! :)
