Answer:

x = 12

Step-by-step explanation:

Solve for x:

\longrightarrow 5 (x - 6) = 2(x + 3)

Expand out terms of the left hand side:

\longrightarrow 5x - 30 = 2(x + 3)

Expand out terms of the right hand side:

\longrightarrow 5x - 30 = 2x + 6

Subtract 2x from both sides:

\longrightarrow (5x - 2x) - 30 = (2x - 2x) + 6

5x - 2x = 3x:

\longrightarrow 3x - 30 = (2x - 2x) + 6

2x - 2x = 0:

\longrightarrow 3x - 30 = 6

Add 30 to both sides:

\longrightarrow 3x + (30 - 30) = 30 + 6

30 - 30 = 0:

\longrightarrow 3x = 6 + 30

6 + 30 = 36:

\longrightarrow 3x = 36

Divide both sides of 3x = 36 by 3:

\longrightarrow \sf \dfrac{3}{3}x = \dfrac{36}{3}

\sf \dfrac{3}{3} = 1:

\longrightarrow \sf x = \dfrac{36}{3}

\sf \dfrac{36}{3} = 12:

\longrightarrow x = 12

Ana Completed 40% of her homework assignment How to Assignments contain 30 math problems how many problems does Anna still need
yulyashka [42]

Answer:

18

Step-by-step explanation:

30*0.4=12

This means 40% of 30 is 12 and Ana has completed 12 problems.

30-12 = 18, so she still needs to do 18 problems.

A diver jumps off a 20 foot high diving board with an initial upward velocity of 4 feet per second. Use the vertical motion mode
Pachacha [2.7K]

The height is represented by h = -16t² + 4t + 20 and There is only one solution, because the solutions indicate time and time cannot be negative.

<h3>How to solve vertical motion models?</h3>

We are given the vertical model of the diver's jump as;

h = -16t² + vt + s

where;

h is height

t is time

v is velocity

s is distance

A) We are given;

Distance; s = 20 ft

velocity; v = 4 ft/s

Thus;

h = -16t² + 4t + 20

B) The solution of the model is gotten from;

-16t² + 4t + 20 = 0

Solving this quadratic equation gives;

t = 1.25 seconds or -1 second

C) B. There is only one solution, because the solutions indicate time and time cannot be negative.
