Answer:
12
Step-by-step explanation:
16+14-6/10-8
30-6/2
24/2
12
Assuming yo mean $8.798
ok, so look at the cents ones
9
look at previous term
8
8 is bigger than 5 so round up
9 rounded up is 10
so
8.80 is rounded
The number of hours spent lifeguarding and clearing tables is 5.4 hours and 8.6 hours respectively
<h3>Solving inequality equation</h3>
- x = number of hours lifeguarding
- y = number of hours clearing tables
x + y ≤ 14 (1)
19x + 9y ≤ 180 (2)
From (1)
x = 14 - y
substitute into (2)
19x + 9y ≤ 180
19(14 - y) + 9y ≤ 180
266 - 19y + 9y ≤ 180
- 19y + 9y ≤ 180 - 266
- 10y ≤ -86
y ≤ -86 / -10
y ≤ 8.6 hours
x + y ≤ 14
x + 8.6 ≤ 14
x ≤ 14 - 8.6
x ≤ 5.4 hours

Answer:
<h2>
<em><u>w</u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>1</u></em><em><u>0</u></em></h2>
Step-by-step explanation:
Simplifying
14 + 12w = -16 + 9w
Solving
14 + 12w = -16 + 9w
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '-9w' to each side of the equation.
14 + 12w + -9w = -16 + 9w + -9w
Combine like terms: 12w + -9w = 3w
14 + 3w = -16 + 9w + -9w
Combine like terms: 9w + -9w = 0
14 + 3w = -16 + 0
14 + 3w = -16
Add '-14' to each side of the equation.
14 + -14 + 3w = -16 + -14
Combine like terms: 14 + -14 = 0
0 + 3w = -16 + -14
3w = -16 + -14
Combine like terms: -16 + -14 = -30
3w = -30
Divide each side by '3'.
w = -10
Simplifying
w = -10
