Answer:
Step-by-step explanation:
Just Square the numbers like a normal equation.
4² = 16
9² = 81
This gives us
or 0.198 as a decimal (approx)
Yes! Let me help you!
Here is the original equation, lets solve this step-by-step
(x + 2)/4 = 5
Now, lets find out how.
We must apply the inverse operation.
4/2 is the reciprocal, so lets multiply that to both sides.
4/2 = 2
5*4 = 20
4x + 8 = 20
-8 -8 Subtract 8 from both sides. (Inverse operation)
4x = 12
4x/4 = 12/4 Divide 4 by both sides (Inverse)
x = 12/4
x = 3 Simplified
Answer: x = 3
Answer:
24
Step-by-step explanation:
600/25
25 goes into 600 24 times
so 600/25 could be reduced to a whole number, 24
Answer:
Mr. James can give each class 13 paint brushes and have one left over.
Step-by-step explanation:
Since he can't give a class a fraction of a paint brush, you don't divide any farther and get a remainder of 1. I attached a picture of the long division.
Answer:
-50
Step-by-step explanation:
42+=x-2x-8
42=-x-8
(add 8 to both sides)
50=-x
(divide by negative 1)
-50=x
