Solve 4.9 + .1 +.9

4.9 + .1 + .9 Step 1 - add .1 to .9 4.9 + 1 Step 2 - simplify 5

### Subject: Algebra

Solve the equation 5 ( -3x - 2 ) - ( x - 3 ) = -4 ( 4x + 5 ) +13

Step 1 - distribute the 5 -15x - 10 - x - 3 = -4 ( 4x + 5 ) + 13 Step 2- distribute the -4 -15x - 10 - x - 3 = -16x - 20 + 13 Step 3 - combine like terms for left side -15x - 13 = -16x -20 +13 Step 4 - combine like terms for right side -15x - 13 = -16x -7 Step 5 - add 13 to both sides -15x = -16x + 6 Step 6 - add 16x to both sides x = 6

### Subject: Physics

A plane is at rest. It then accelerates down a runway at 3 m/s^2 for 40 seconds. Determine the distance traveled.

given: a=3, t=40, Vi= 0. Use the kinematic equation d = Vi * t + 1/2 * a * t^2 step 1 - plug in given. d = (0) * (40) + 1/2 * (3) * (40)^2 step 2- solve d = 40 m
