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

-4.9x = 9.8    Divide both sides by -4.9

x = 9.8/-4.9.    Use a calculator.

x = -2.         Answer is - because + /-    =   -

I hope this helps.

irinina [24]

Answer: He needs a minimum of 2011.25 hours

Step-by-step explanation:

In order for Gavin to get his private pilot certificate he must fly solo.

He must fly a minimum of 2020 hours with his plane instructor before he can fly solo.

He has already flown 8 3/4 hours with his instructor. This is express as 8hours + (3/4 × 1) = 8.75 hours

2020 - 8.75 = 2011.25.

He needs a minimum of 2011.25 hours

The formula for finding the perimeter, P, of a rectangle with length l and width w is given. P=2l+2w
Ivenika [448]

Answer:

The formula to determine the length of rectangle with perimeter and width is L = \frac{P - 2W}{2}

Step-by-step explanation:

Given as :

The perimeter of rectangle = P

The length of rectangle = L

The width of rectangle = W

∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width

I.e  P = 2 L + 2 W

Or, 2 L = P - 2 W

∴     L = \frac{P - 2W}{2}

Hence The formula to determine the length of rectangle with perimeter and width is L = \frac{P - 2W}{2}    Answer
