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.

A certain value divided by 7 is proportional to the division of 9.2 by 16.1.
lesya692 [45]

x/7 has to be proportionate to 9.2/16.1 so find out how 7 relates to 16.1

16.1/7=2.3 and 7*2.3=16.1

then apply it to x and 9.2

9.2/2.3= 4 and 4*2.3=9.2

So, x=4
