Solve for n:
8n=56
A. n = 1/7
B. n= 7
C. n=48
D. n=64
E. n=448
To solve for n, we can divide both sides of the equation by 8:
8n/8 = 56/8
This simplifies to:
n = 7
Therefore, the answer is B. n = 7.
more explanation
To solve for n, we want to isolate n on one side of the equation.
Starting with the equation 8n = 56, we can divide both sides by 8 to undo the multiplication of n by 8.
8n/8 = 56/8
This simplifies to n = 7.
So, the solution is n = 7.
In this case, option B is the correct answer: n = 7.
Solve for x:
51 = 3x
A. x=3
B. x = 17
C. x=48
D. x=54
E. x=153
To solve for x, we need to isolate x on one side of the equation.
Starting with the equation 51 = 3x, we can divide both sides by 3 to undo the multiplication of x by 3.
51/3 = 3x/3
This simplifies to 17 = x.
So, the solution is x = 17.
Therefore, the answer is B. x = 17.
To solve for n, we can divide both sides of the equation by 8:
(8n) / 8 = 56 / 8
This simplifies to:
n = 7
Therefore, the answer is B. n = 7.
To solve for n in the equation 8n = 56, you need to isolate n by dividing both sides of the equation by 8.
Dividing both sides by 8, you get:
(8n)/8 = 56/8
n = 7.
Therefore, the correct answer is B. n = 7.
