About 80% of a cookie each
-5+(-4)
-5-4
-9
Therefore, -9 is the correct answer
-3X+4=16
Subtract 4 from each side.
-3x+4-4=16-4
-3x=12
Divide each side by -3.
x=-4
I hope this helps!
Answer:
Answer in step-by-step.
Step-by-step explanation:
What do you notice...:
- Each equation has a solution equivalent to the other.
What do you note about the graphs...:
- Each graph for the individual equations are equivalent.
What do you notice about each of the equations:
- Equations can be reduced, and signs can be shifted.
What generalization....:
Some equations can be reduced to be made equivalent to the other. Some equations can also be made equivalent by multiplying both sides of the equation by -1 to make the y positive.
Answer:
a = c/(d - r)
Step-by-step explanation:
Multiply both sides by a
(c/a)a = (d - r)*a Notice how this is written. You need to introduce brackets on the right because both d and r are multiplied by a.
c = (d - r)*a
Divide both sides by (d - r)
c/(d - r) = a*(d - r)/(d - r)
c/(d - r) = a
