How do you solve for M in the formula?<br>Give Steps Please!​
Murljashka [212]

Answer:

m = \frac{gs^{2}}{10}

Step-by-step explanation:

g = 10(\frac{m}{s^{2} })

simplify:

g = \frac{10m}{s^{2}}

multiply both sides by s²:

gs² = 10m

divide both sides by 10:

m = \frac{gs^{2}}{10}

I need serious help, I forgot how to do this ;-; I haven't done that kind of math in a long time. How can I find the answer and
larisa [96]

Answer:

I think your answer is 85. The 50 degree angle on the left side of E is equal to the angle to the right of E. Since both triangles have equivalent angle measurements, D and B are correspondent of one another. Add the 50 degrees to the 45 degrees to get 95. Since triangles total measurements equal 180, subtract 95 from 180 to get 85. Angle D = 85, and since Angle B is correspondent, Angle B = 85°

Solve the system of equations given below.<br> y - 15 = 3<br> -2.1 + 5y = -3
EastWind [94]

Answer:

1) y=18

2)y=-0.18

Step-by-step explanation:

1) y-15=3. Add 15 on both sides.

y=18

2)-2.1+5y=-3. Add 2.1 on both sides

5y=-0.9. Divide 5 on both sides

y=-0.18
