Answer:
Step-by-step explanation:
So we have the equation:
First, subtract 4 from both sides:
Definition of Absolute Value:
Add 2 to both sides for both equations:
And we're done!
Xy = -112
x + y = -54
x + y = -54
2 + y = -54
- 2 - 2
y = -56
(x, y) = (2, -56)
or
x + y = -54
-56 + y = -54
+ 56 + 56
y = 2
(x, y) = (-56, 2)
The two numbers that multiply to -12 and add up to -54 are -56 and 2.
Answer: 2500
Step-by-step explanation: 250 spins times the amount of greens expected equals 2500.
This is because Andrea converted the Percentage wrong.
to Convert a Percent to a Decimal, she should have divided by 100
so 5 divided by 100 = 0.05 [not 0.5]
Andrea should have multiplied 300 by 0.05 instead to get the right answer
quickly finding 10% of a number means to simply move the decimal to the left one place
so 10% of 300 is 30
since 5% is half of 10%
half of 30 is 15
and so 5% of 300 is 15
