Answer:

solving the equation 5x^2 - 16 = 29 we get the solution: \mathbf{x=3,x=-3}

Step-by-step explanation:

We need to solve the equation 5x^2 - 16 = 29

We need to solve the equation to find the value of x.

We can solve this equation using simple DMAS rule.

We are given:

5x^2 - 16 = 29

Add 16 on both sides

5x^2 - 16+16 = 29+16\\5x^2=45

Now, divide both sides by 5

\frac{5x^2}{5}=\frac{45}{5} \\x^2=9

Now, we know that \sqrt{x^2}=\pm x

Taking square root on both sides.

\sqrt{x^2}=\sqrt{9}\\x=\pm3

So, we get values of x:

x=3, x=-3

Therefore, solving the equation 5x^2 - 16 = 29 we get the solution: \mathbf{x=3,x=-3}

mihalych1998 [28]
The experimental probability is

  (number of times it stopped over Sect. 2) / (total number of times you tried it)

Number of times it stopped in Section-2: 36

Total number of times you tried it:  (20 + 36 + 24)  =  80

Experimental probability of Section-2  =  36/80 = 9/20  =  45%

the perimeter of a rectangle is 55 inches. the ratio of the length to width is 7:4. use proportions to find the area of the rect
Leni [432]

Answer:

Step-by-step explanation:

let : x the length and y the width    .... ( x  > y and x ; y reals numbers )

the perimeter is : 2(x+y)

2(x+y) = 55...(1)

x/y = 7/4 ...(2)

by (2) : x = (7/4)y

subsct in (1) : 2( (7/4)y +y ) =55

(7/2)y +2y =55

multiply by 2

7y +4y = 110

11y = 110

y = 10

x = (7/4)(10)

x = 35/2
