The sum of two numbers is 61 . The larger number is 5 more than the smaller number. What are the numbers?

Elanso [62]

Answer:

35.5 and 25.5

Step-by-step explanation:

all you have to do is take 61÷2=30.5 and you add five to one of the halves, and subtract five form the other.

61÷2= 30.5

30.5+5= 35.5

30.5-5= 25.5

What the answer X/3=3

galina1969 [7]

Answer:

x = 9

Step-by-step explanation:

Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Multiply 3 to both sides.

(x/3)(3) = 3(3)

x = 3(3)

x = 3 * 3

x = 9

x = 9 is your answer.

How is this equation completed? I cannot find any examples in the book.

Answer: Option D

$t_{max} =19\ s$

Step-by-step explanation:

Note that the projectile height as a function of time is given by the quadratic equation

$h = -12t ^ 2 + 456t$

To find the maximum height of the projectile we must find the maximum value of the quadratic function.

By definition the maximum value of a quadratic equation of the form

$at ^ 2 + bt + c$ is located on the vertex of the parabola:

$t_{max}= -\frac{b}{2a}$

Where $a$

In this case the equation is: $h = -12t ^ 2 + 456t$

Then

$a=-12\\b=456\\c=0$

So:

$t_{max} = -\frac{456}{2*(-12)}$

$t_{max} =19\ s$
