Solve the following equation for X: 1/2(5x+12)=2x-3 show your work

Debora [2.8K]

1/2(5x + 12) = 2x - 3
5/2 x + 6 = 2x - 3
5/2 x - 2x = -3 - 6 = -9
5x = 2 x -9 = -18
x = -18/5

What is -15.5t + 13.24 = -13.44 + 10.56 – 3.1t

Tatiana [17]

First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:

-15.5t + 3.1t = -13.44 + 10.56 - 13.24

Now combine the numbers on both sides of the equation and solve for t:

-12.4t = -16. 12
t = 1.3

Hope this helps!

If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.

shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

$h(t) = -16t^2 + 144$

When will the object hit the ground?

It hits the ground after t seconds, and t is found when $h(t) = 0$ . So

$h(t) = -16t^2 + 144$

$0 = -16t^2 + 144$

$16t^2 = 144$

$t^2 = \frac{144}{16}$

$t^2 = 9$

$t = \sqrt{9}$

$t = 3$

3 seconds, so the correct answer is given by option a.
