Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.

x² - x - 12 ≠ 0
x² - 4x + 3x - 12 ≠ 0
x (x - 4) + 3 (x - 4) ≠ 0
(x + 3)(x - 4) ≠ 0
x ≠ -3 or x ≠ 4

Answer:
1/2
Step-by-step explanation:
myltiply 2/3 by 2/2 and then subtact 1/6 from the new 4/6 to give you 3/6. it simplifies to 1/2
To solve this, we must find 93% of 8.15 ounces.
'Of' in mathematics means multiplication.
93% can also be written as a fraction, or a decimal: 0.93
0.93 * 8.15 = 7.5795
We can round this to 7.58 (nearest hundredth).
7.58 ounces of silver are in the bar.
Answer:
0.037
Step-by-step explanation:
If the hitter makes an out 72% of the time, then the probabilty that he makes hit in 1 at-bat is
and the probabilty that he doesn't make hit in 1 at-bat is 
The probability that the hitter makes 10 outs in 10 consecutive at-bats, assuming at-bats are independent events is
