Answer:
It is already solved!
Step-by-step explanation:
It is meant to be in y = mx + b form where x is the slope and b is is the y-intercept.
A ratio is not multiplication, so I'm just going to throw that out there first in case any other answers trip you up.
9:2 is the correct answer because there are 9 sandwiches for 2 people.
Answer:
The answer is 7/24.
Step-by-step explanation:
I attached a picture, but I'll try to walk through it here.
1) A negative and a negative makes a positive, so h becomes positive.
2) I added 7/8 to both sides, in order to "isolate the variable", which simply means to get h by itself, on one side of the equation (you'll likely hear it said both ways).
3) I multiplied 7/8 by 3/3, and multiplied -7/12 by 2/2. This is known as a common denominator, which in this case is 24. You can only add and subtract fractions that have a common denominator.
4) Multiply both of the fractions to get 21/24 + (-14/24). "Adding a negative" is the same thing as subtracting.
5) 21 - 14 = 7, and since our denominators are the same, the answer is 7/24.
You can confirm the answer by substituting, or "plugging" 7/24 into your original equation, in place of h.
Answer:
n= 16
Step-by-step explanation:
Answer:
Its the last one a^2/b.
Step-by-step explanation:
(a^6 b^-3)^1/3
= a ^(6 * 1/3) b^(-3*1/3)
= a^2b^-1
= a^2/b.
