The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +

prisoha [69]

Let

x------> the first even integer

x+2---->the second even integer

x+3---->the third even integer

we know that

$x+(x+2)+(x+4)=36$ -----> equation that represent the situation

solve for x

Combine like terms in the left side

$(x+x+x)+(2+4)=36$

$3x+6=36$

therefore

<u>the answer is the option B</u>

$3x+6=36$

How can you use proportional reasoning to solve problems involving percent

Oksana_A [137]

Example A, Step 1: Write a comparing the percent to the ratio of part to whole. ex- ?/25 = 28/100 *Notice that 25 is a factor of 100* Step 2: Find the multiplication factor. ex- ?*4 = 28 and 25*4 = 100 *Since 25*4 = 100, find what number times 4 equals 28* Step 3: Find the numerator. ex- 7/25 = 28/100 *Since 4*7 = 28, 28% of 25 = 7 Example B, Step 1: Write the percent as a fraction. ex-35% of 60 = 35/100 of 60 Step 2: Multiply. ex- 35/100 of 60 = 35/100x60=2100/100=21 *Simplify* Example C, Step 1: Write the percent as a decimal. ex- 5% = 5/100 = 0.05 Step 2: Multiply. ex- 180 * 0.05 = 9, 5% of 180 is 9.

Step-by-step explanation:

We know that the height of water in a pool decreased 5 inches per week.

This means that we can form the equation $y=-5x$ , since the amount of water remaining is proportionate to the amount of weeks that have passed.
