Answer:
7
Step-by-step explanation:
12x+6=90
12x=84
x=7
The two numbers are 4.95 and 2.25.
<h3>
Explanation: </h3>
Let the two numbers be x and y. Given conditions,
...............................(1)
................................(2)
Adding equations (1) and (2), we get
Therefore
x=4.95 .......................(3)
Substituting value of x from (3) in (1), we get
y=2.25 ........................(4)
From (3) and (4), the two numbers are 4.95 and 2.25.

Step-by-step explanation:
Answer: The filled out table is shown in the attachment below
Row 1 = 2, 4, 8
Row 2 = 6, 36, 216
=======================================================
Explanation:
In the first row we have x^2 = 4. Apply the square root to both sides to get x = 2. It appears your teacher is making x positive.
So we'll have 2 in the first box of row 1.
If x = 2, then x^3 = 8 after cubing both sides.
In other words, x^3 = 2^3 = 2*2*2 = 8
The value 8 goes in the other box of row 1.
---------------
For row 2, we use x = 6 to square that to get x^2 = 6^2 = 6*6 = 36.
36 will go in the blank box for row 2
Divide 42 by 6 to get the space one bag covers. so once you do that, you get 7. then multiply that by 10 to get the number of space all 10 bags cover and you get 70m. hope i helped :3
