Add the amount of choices, and divide by the number of customers surveyed.

40 + 32 + 8 + 20 = 100

40 customers were surveyed

100/40 = 2.5

The average number should be D) 2.5

Pls asap completing square X^2 -24x+5=0

anzhelika [568]

Answer:

Step-by-step explanation:

x² - 24x + 5 = 0

x² - 24x = -5

Now divide the co efficient of x by 2 and square the quotient and add to both sides

24/2 = 12

12² = 144. Now add 144 to both sides of the equation.

x² - 24x + 144 = 5 + 144

x² - 24x + 144 = 149

x² - 2*12*x + 12² = 149

(x - 12)² = 149

Both sides take square root

x - 12 = ±√149

x = 12 ± √149

If 16 is added to one-third of a number, the result is three times the number. What is the number?

AnnZ [28]

First set up the equation based on the description.

$\frac{1}{3}$ x + 16 = 3x

Use subtraction to get the "x"s on one side of the equation. You can next subtract $\frac{1}{3}$ x from both sides.

16 = $\frac{8}{3}$ x

Now you can multiply both sides of the equation by $\frac{3}{8}$ to solve for x

x = 6

Jimmy was supposed to multiply a certain number by 43 but by mistake he multiplied that number by 34 as a result his answer was

vredina [299]

Answer:

345

Step-by-step explanation:

We can solve this problem by two equations. Our variables will be the following:

$x$ is the amount to be multiplied

and $y$ is the amount that should be obtained by multiplying by 43

Thus our first equation is:

$43x=y$

But the problem tells us that there was an error and the number $x$ was multiplied by 34, so the result failed by 3105, thus the second equation is as follows:

$34x=y-3105$
