Question

0.1m+8-12nwhenm=30n=1/4

Answer 1

Answer:

The answer is 8.

Step-by-step explanation:

Plugging in n and m in the equation, we have,

0.1 * (30) + 8 - (12) * (1/4) = ? → equation 1

Then we apply PEMDAS to solve.

Solve 0.1 * 30 first; 0.1*30 = 3

Then 12 * 1/4; 12 * 1/4 = 3

Put the values from above to equation 1

Now we have 3 + 8 - 3 = ?

Keeping the PEMDAS in mind, addition first before subtraction.

3 + 8 = 11

11 - 3 = 8

Therefore the answer is 8.

Answer 2

Answer:

8

Step-by-step explanation:

All you need to do is plug in m and n.

m=30

n=1/4

0.1m+8-12n

0.1(30)+8-12(1/4)=8
