Answer:
x = 15
Step-by-step explanation:
Simplifying
3x + (8x + 15) = 180
Reorder the terms:
3x + (15 + 8x) = 180
Remove parenthesis around (15 + 8x)
3x + 15 + 8x = 180
Reorder the terms:
15 + 3x + 8x = 180
Combine like terms: 3x + 8x = 11x
15 + 11x = 180
Solving
15 + 11x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 11x = 180 + -15
Combine like terms: 15 + -15 = 0
0 + 11x = 180 + -15
11x = 180 + -15
Combine like terms: 180 + -15 = 165
11x = 165
Divide each side by '11'.
x = 15
Simplifying
x = 15
Answer:
x > 3
Step-by-step explanation:

Answer:
Since 1 km = 1000 m, the lawnmowers top speed would be 8000 m/h.
Step-by-step explanation:
The limit values of the indicated value, 2 pounds, are the boundaries.
The boundaries of 2 pounds are;
<h3>Method used to find the boundaries of the indicated value</h3>
The boundaries of an indicated value are the upper and lower bounds of
the value, which are the possible minimum or maximum values the
number may be before being rounded to the current value.
The indicated value = 2 pounds
The lowest possible value, 2 pounds can be before rounding up is 1.5 pounds.
Therefore;
- 1.5 pounds is the lower bound of 2 pounds.
The highest possible value of 2 pounds is 2.44999... pounds which is approximately 2.5 pounds
Therefore;
- The upper bound of 2 pounds is 2.5 pounds
Which gives;
The boundaries of 2 pounds are;
