Which of the following lists is in order from smallest to largest?
Stells [14]

Answer:

The following list is in order from smallest to largest is 17\%,0.175,\frac{2}{11},\frac{1}{5}

Step-by-step explanation:

Let the numbers be \frac{2}{11},\frac{1}{5},17\%,0.175

To find the list in order from smallest to largest:

\frac{2}{11},\frac{1}{5},17\%,0.175

Rewritting the above numbers as below

0.18,0.5,\frac{17}{100},0.175

0.18,0.5,0.17,0.175

Now arranging the numbers in order from smallest to largest

0.17,0.175,0.18,0.5

\frac{17}{100},0.175,\frac{2}{11},\frac{1}{5}

The arranged numbers can be written as

17\%,0.175,\frac{2}{11},\frac{1}{5}

The following list is the order from smallest to largest is 17\%,0.175,\frac{2}{11},\frac{1}{5}

Solve the system of linear equations below.
sergiy2304 [10]

Answer:

Step-by-step explanation:

Let's use the addition/elimination method to solve this.  If we multiply the first equation through by -1 we can eliminate the x terms.  Doing that gives us:

 -x  +  3y  =  3

  x  +  3y  =  9

The x's subtract each other away leaving us with

6y = 12 so

y = 2.

Now we will plug in 2 for y in either of the original equations to solve for x:

x + 3(2) = 9 and

x + 6 = 9 so

x = 3

The coordinate for the solution is (3, 2) or x = 3, y = 2

The second choice down is the one you want.
