So this is what you do...
Turn this: a + (-5) = -12, into this: a - 5 = -12...(they are the same thing it just makes it easier to solve)
a - 5 = -12
Add 5 to both sides.
a = -7
So -7 is the answer. I hope this helps love! :)
The gross income earned by the workers if paid time and a half on Saturdays and double time on Sundays is $180.06
<h3>
How to find gross income</h3>
Total = 10.75(1.5)(x) + 10.75(2)(y)
where,
- x = hours worked on Saturday = 4.5 hours
- y = hours worked on Sunday = 5 hours
Total = 10.75(1.5)(4.5) + 10.75(2)(5)
= 72.5625 + 107.5
= $180.0625
Approximately,
$180.06

There are 36 outcomes when rolling a pair of dice.
The ones adding up to 8 are: (2,6),(3,5),(4,4),(5,3),(6,2).
So the probability of rolling a sum of 8 is 5/36.
With three (independent) random throws, the probability of having a sum of 8 at least once equals 1-probability of no 8 at all.
P(not 8)=1-5/36=31/36
For this to happen three times, we use the multiplication rule
P(not 8 three times)=(31/36)^3=29791/46656=
Therefore
P(sum of 8 at least once)=1-29791/46656=16865/46656
[=0.3615 approx.]
Answer:
10.9
Step-by-step explanation:
You can solve this using the Pythagorean theorem, a^2+b^2=c^2, since it will form a right triangle.
You aren't missing the hypotenuse (c), but one of the side lengths (b). But you still solve like a normal algebraic equation.
Plugging in your values, you should start with 5^2+b^2=12^2
Then square everything.
25+b^2=144
Take away 25 from both sides.
b^2= 119
Then square root both sides.
b= 10.9
