\text{10 more than a number is greater than 50} 

\text{Let the number be represented by the variable x} 

x+10\ \textgreater \ 50 \text{Isolate variable x}

x=50-10  \text{Subtract 10 from both sides of the equation}

x=40  \text{Solution}

10 more than (+ 10) a number (x) is greater than (>) 50

x + 10 > 50

To solve, subtract 10 from both sides.

x > 40

A ball is dropped from a height of 64 feet. Its height, in feet, can be modeled by the function h(t) = -167 + 64, where t is the
Oliga [24]

Answer:

Step-by-step explanation:

Known facts:

  • the ball dropped from a height of 64 feet
  • function h(t) = -16t^{2}  + 64

First question:

  • the ball hits the ground when h(t) = 0, thus we get the equation

                      -16t^{2} +64 = 0\\16t^{2} = 64\\t^{2} =4\\t = 2

     So the ball hits the ground in 2s

Second question

  • to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28

                      -16t^{2} +64 = 28\\16t^{2} = 36\\t = \frac{6}{4} =1.5s

      So the ball hits the ground in 1.5s

Hope that helps!

Solve the equation for x, where x is a real number (5 points): <br> 2x^2 + 15x + 4 = 0
vitfil [10]
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                           x  = [ -b ± √(b^2 - 4ac) ] / (2a)
                           x = [ -15 ± √((15)^2 - 4(2)(4)) ] / ( 2(2) )
                           x = [-15 ± √(225 - (32) ) ] / ( 4 )
                           x = [-15 ± √(193) ] / ( 4)
                           x = [-15 ± sqrt(193) ] / ( 4 )
                           x = -15/4 ± sqrt(193)/4
The answers are -15/4 + sqrt(193)/4 and -15/4 - sqrt(193)/4.

Is the square root of 42 rational or irrational? Explain
MA_775_DIABLO [31]

<em>☽------------❀-------------☾</em>

<em>Hi there!</em>

<em>~</em>

\sqrt{42}<em> ≈ </em>6.4807406984087...

<em>So </em>\sqrt{42}<em> is irrational (since the decimal portion doesn't terminate or repeat) </em>

Select the correct answer.
Alika [10]
<h3>I'll teach you how to solve x= 12 - y, 2x + 3y = 29</h3>

------------------------------------------------------------

x= 12 - y, 2x + 3y = 29

Substitute x=12-y:

[2(12-y)+3y=29]

Isolate y for 2(12-y)+3y=29:

2(12-y)+3y=29= y= 5

Substitute y=5:

x=12-5

12-5= 7

x=7

Your Answer Is (C) x=7, y=5

plz mark me as brainliest if this helped :)
