Question

What are numbers 13 and 14

Answer 1

Answer:

13. 15

14. 3

Step-by-step explanation:

Translate words into an equation by taking apart sections. Then isolate the variable.

13. 27 is 12 more than a number x

"27" 27

"is" =

"12 more than a number x" x + 12

27 = x + 12

27 - 12 = x + 12 - 12   Subtract 12 from both sides. "x" will be isolated (alone).

15 = x   Answer

x = 15   Writing variable on the left side is standrad

14. The difference of a number p and -9 is 12

"The difference of a number p and -9" |p - (-9)|

"is" =

"12" 12

|p - (-9)| = 12     Subtracting a negative number becomes adding

|p + 9| = 12

|p + 9 - 9| = 12 - 9    Subtract 9 from both sides

p = 3    The | | can be worked around, it just keeps "p" positive.
