Evaluate 12 − 6 + (14 − 8)2 = . (1 point)

18

Step-by-step explanation:

you do PEMDAS

there is parenthesis

12-6+6 times 2

there is multiplication

12-6+12

then there is subtraction and addition so you have to do it left to right

18

18

Step-by-step explanation:

When solving these types of questions, you want to remember PEMDAS. According to PEMDAS, P is parenthesis. (14-8) is in parenthesis. 14-8 is 6.

Now the equation looks like this:

12-6 + (6)2

There are no Exponents in this equation, but there is multiplication. If there are no operations between two integers, that means it is likely to be multiplication. 6 x 2 is 12.

Now the equation looks like this:

12-6+ 12

Even though, according to PEMDAS, Addition is before subtraction, you can do either one from left to right. Even with multplication and division.

Now the equation looks like this:

6+12

Obviously 6+12 is 18. So, 18 is the answer.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer: it's d
