To get x alone, you have to divide -4.9 to both sides. The reason you have to divide is because division is the opposite of multiplication
This is what you call a one step equation
-4.9x = 9.8
x = 9.8/-4.9
x= -2
The percentage of the bags of cement that would weigh less than 50 lbs. would be 50% because the normal distribution is symmetrical, and since the mean is your midpoint, then it would be 50% higher, and 50% lower.
Y equals 4x-2 that is my awnser
Here, Sin Ф = P / H
Sin 31 = x / 430
0.515 = x /430
x = 430 * 0.515
x = 221.45
In short, Your Answer would be 221.45
Hope this helps!
