Mathematics
1 answer:
miss Akunina [59]2 years ago
8 0

Answer:

50

Step-by-step explanation:

7x = (90 + 5x) \times  \frac{1}{2}

7x =   {2.5x} + 45

4.5x = 45

x = 10

Plug 10 in for x.

5(10) = 50

Which is the best first step to write this in standard form?
goldenfox [79]

Answer:

<em>Set the function equal to 0</em>

Step-by-step explanation:

<u>Standard Form of the Quadratic Equation</u>

The form

ax^2+bx+c=0

is called the standard form of a quadratic equation. It can be clearly identified the terms of a second-degree polynomial equated to 0.

The equation is given in the form:

2(x-4)^2-3=8

And we need to operate the expression to make it look like a standard form. The first logical step should be to set the function equal to 0 and then start to operate the resulting expression. It can be done by subtracting 8 on both sides of the equation:

2(x-4)^2-3-8=0

Answer: Set the function equal to 0

Which inequality represents all values of x for which the product below is defined
zavuch27 [327]

Answer:

(-∞, -2) ∪ (0, ∞)

Step-by-step explanation:

Multiply together the (7x) and the (x+2), obtaining 7x^2 + 14x.  This is the correct argument (input) to Answer A.

Since the domain of the square root function includes "all real numbers equal to or greater than 0," we set 7x^2 + 14x = to 0.  This factors to the original 7x*(x+2), set equal to 0.  The roots are 0 and -2.  

These two values create three intervals:  (-∞, -2), (-2, 0) and (0, ∞).

Choosing test numbers, one from each interval:  {-5, -1, 1}.

7x^2 + 14x is + at x = -5, - at x = -1, and + at x = 1.

Thus, the domain of this function is  (-∞, -2) ∪ (0, ∞).  In other words, the product shown is defined on  (-∞, -2) ∪ (0, ∞).

Please help me <br><br> 6th grade math
Marta_Voda [28]

Answer:

Late response, sorry. It is 750 meters.

Step-by-step explanation:

An easy method to save time is to just divide the distance by time to find what amount per second it can run. In this case, you have 120 and 4 to work with. Divide and you'll get 30 meters per second. Then, multiply 25(your seconds) by 30(the meters it runs per second) to get your answer.
