Answer:
-1
Step-by-step explanation:
1.)Reorder the terms:
7(8 + x) = 49
(8 * 7 + x * 7) = 49
(56 + 7x) = 49
2.)Solving
56 + 7x = 49
3.)Solving for variable 'x'.
4.)Move all terms containing x to the left, all other terms to the right.
5.)Add '-56' to each side of the equation.
56 + -56 + 7x = 49 + -56
6.)Combine like terms: 56 + -56 = 0
0 + 7x = 49 + -56
7x = 49 + -56
7.)Combine like terms: 49 + -56 = -7
7x = -7
8.)Divide each side by '7'.
x = -1
9.)Simplifying
x = -1

Answer:
b). 11.85
Step-by-step explanation:
The rule is add 0.9
1.95 + 0.9 = 2.85
2.85 + 0.9 = 3.75
3.75 + 0.9 = 4.65...
if you were to add 7 more times you will get to 11.85.
*Here's a trick to make it shorter*
11 × 0.9 = 9.9
9.9 + 1.95 = 11.85
hopefully this helped :3
Since all of the aides are equal as the labeled hash marks say, just count up all of the sides and divide 48 (the perimeter) by that number (8) and you’ll get an answer of 6
