Answer:

X = 6

Step-by-step explanation:

<h3>I hope you can understand it;</h3>

- 3x + 12 + x = 2x - 12

2x + 12 = 2x -12

2x - 2x = - 12 - 12

-4x = -24

x = 24/4

x = 6

Answer:

x=6

Step-by-step explanation:

1)  Expand the equation to -2x+12=2x-12

2) Subtract 12 from both sides which gives you -2x=2x-24

3) Simplify, which makes it -4x=-24

4) Divide by 4, which gives you 6.

Can anyone help me????
Ne4ueva [31]

Answer:

Ed used 39/60 of one hour to complete his tasks.

Step-by-step explanation:

Find the least common denominator (LCD), which would be 20

Then, find how to get from 5 to 20 and 4 to 20.

Use division.

20/5 = 4, 20/4 = 5

After this, multiply the numerator to the according number.

2*4 = 8 = 8/20

1*5 = 5 = 5/20

Make the denominator 60 to represent 60 minutes in one hour

5/20*3/3 = 15/60

8/20*3/3 = 24/60

Add the two results.

15/60 + 24/60 = 39/60

PROBLEM 2 The height of a golf ball in feet can be determined using the formula h(t) = -16t2 + 100x , where t is the number of s
wolverine [178]

Answer:

<h3>H. 150 ft</h3>

Step-by-step explanation:

Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;

h(t) = -16t^2 + 100x\\\\h(2.5) = -16(2.5)^2 + 100(2.5)\\\\h(2.5) = -16(6.25) + 250\\\\h(2.5) = -100+250\\\\h(2.5) = 150\\\\

Hence the height of the golf after 2.5 seconds is 150ft.
