So first you would divide the 10 by 2
-4=12p+5
Then you subtract the five from both sides to try to isolate the variable p
-4=12p+5
-5 -5
You then divide both sides by 12 to solve for p and simplify
-9=12p
(-9/12)=(12p/12)
-3/4=p
What's up? this answer is B, 72
we can figure out that one third of melissa's age is 24 because 18+6= 24. simply eliminate the obvious incorrect answers, A and C. 78/3= 26 so it isn't D
72/3=24 it is B
best of luck with your studies
Answer:
(x - 5)(x + 3)
Step-by-step explanation:
to solve x² - 2x = 15, we need to get all the terms on one side so we can solve the quadratic equation using factoring. to do this, we subtract 15 from both sides
x² - 2x = 15
- 15 -15
x² - 2x - 15 = 0
now we can factor. we need 2 numbers that when multiplied together give us -15, and when those 2 numbers are added together we get -2
because we have a -15, we can assume that one number must be negative and the other positive, as a negative times a postive is a negative.
we can use 3 and -5 as factors and test it out. we put x in front because we have an x²
(x - 5)(x + 3) < we can FOIL to check to see if this is correct. its not mandatory to check but when you arent sure of the answer you can FOIL it out
FOIL stands for: First, Outside, Inside, and Last terms
F: (x - 5)(x + 3) = x²
O: (x - 5)(x + 3) = -3x
I: (x - 5)(x + 3) = 5x
L: (x - 5)(x + 3) = -15
x² + 3x - 5x - 15 < subtract 3x from 5x
x² - 2x - 15
this checks out, so our answer is (x - 5)(x + 3)
Answer:
5 times
Step-by-step explanation:
The complete question in the attached figure
we know that
The deep of the bottom of the ship is -15 ft
The deep of the roadway is -75 ft
To find out how many times deeper is the roadway than the bottom of the ship, divide the deep of the roadway by the deep of the bottom of the ship
