Step-by-step explanation:

2 = 2.27 - m/4

I am so bad at math, lol! ^^ HELP ME PWEASE!

Answers

Answer:

m = 1.08

Step-by-step explanation:

Subtract 2.27 from both sides.

2 - 2.27 = -m/4

Simplify  2 - 2.27 to  -0.27.

-0.27 = -m/4

Multiply both sides by 4

-0.27 × 4 = -m

Simplify  -0.27 × 4 to -1.08.

-1.08 = -m

Multiply both sides by -1 (-m is also known as -1)

1.08 =m

Answer:

m = 1.08

Step-by-step explanation:

Basically, we can start off by finding the difference between 2 and 2.27(which is 0.27). Then we can see that 0.27 is equal to m/4. Since 0.27*4=1.08, we can see that m=1.08.
