What is the solution to the system of equations?
Yuri [45]

Answer:

No solution

Step-by-step explanation:

Note how "2x" shows up in both equations.  This suggests doing a substitution to solve the system.

Focus first on the first equation.  Solving 2x - y = 7 for 2x, we get:

2x = y + 7.

Next, we substitute y + 7 for 2x in the second equation:

y = (y + 7) + 3.

Simplifying this produces:

0 = 10

This is not true and can never be true.  Thus, this system has no solution.

AC = 9x - 12, CD = 4x + 18, AD = ?​
GrogVix [38]

If we assume that point C is somewhere on segment AD, then,

AD = AC + CD

AD = (9x-12) + (4x+18)

AD = (9x+4x) + (-12+18)

AD = 13x+6    is the answer

Answer: I think it is 1572 sq feet

Step-by-step explanation:

Lxwxh

14x13x9=1638

Window is 4x4.5=18

Door 1 is8x3=24

Door 2 8x3=24

Since the doors and window are not included in what was painted you need to subtract those totals from the room.

So, 1638-18=1620

1620-48(two doors)=1572 sq feet
