Which of the following number lines represents the solution to -5m=10

m = -2.  This is the 2nd answer choice

Step-by-step explanation:

Let's actually solve -5m=10 for m.  Dividing both sides by -5, we get

m = -2.  This is the 2nd answer choice.

853.3

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
