We are given the steps that are laid to determine the value of x in the expression |2x -4| - 3 = 3. First step is to add 3 to both sides, then simplify, then determine x. The first incorrect step is step 1 since we add not subtract.

Answer:

165 ft^2

Step-by-step explanation:

We need to break the figure into 2 parts

We have the square at the bottom right

The square is 5 by 5

A = 5*5 = 25

The rectangle is then 20 by (12-5) =7

The area of the rectangle is

A = 20 *7 = 140

Add the areas together

140+ 25

165 ft^2

Solution Y is 40 percent sugar by volume, and solution X is 20 percent sugar by volume. How many gallons of solution X must be a

nadya68 [22]

Answer:

(E) 450

Step-by-step explanation:

Let x represent the number of gallons of solution X that must be added to the mix. Then the amount of sugar in the mix is ...

0.20x +0.40·150 = 0.25(150 +x)

0.20x +60 = 37.5 +0.25x . . . eliminate parentheses

22.5 + 0.20x = 0.25x . . . . . . subtract 37.5

22.5 = 0.05x . . . . . . . . . . . . . subtract 0.20x

450 = x . . . . . . . . . . . . . . . . . . multiply by 20

450 gallons of solution X must be added to make a 25% sugar solution.

Montano1993 [528]

Answer:

There is a $5*10^{-9}$ % probability that exactly 2 of them are hit by lightening in a given year

The correct probability distribution to solve this problem is the binomial probability.

This is exact the type of problem that the binomial probability is used, when we want to find the probability of a exact number of events happening in a number of trials.

Step-by-step explanation:

Here we use the binomial probability.

For the binomial probability calculus we have these following parameters.

$n:$ The number of repeated trials
