Answer:

7

Step-by-step explanation:

on the graph, it shows that for every 21 gallons of white paint there are 3 gallons of yellow. Then you divide 3 by 21 and the answer is 7.

Answer:

  x = 42

Step-by-step explanation:

The marked angles are supplementary, so their sum is 180°.

  (2x +8) +(2x +4) = 180

  4x +12 = 180 . . . . . . . . . simplify

  x +3 = 45 . . . . . . . divide by 4 (because we can)

  x = 42 . . . . . . subtract 3

<em>Additional comment</em>

A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and  eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.

The first term of a geometric sequence is 15, and the 5th term of the sequence is <img src="https://tex.z-dn.net/?f=%5Cfrac%7B24
sladkih [1.3K]

The geometric sequence is 15,9,\frac{27}{5},\frac{81}{25},  \frac{243}{125}

Explanation:

Given that the first term of the geometric sequence is 15

The fifth term of the sequence is \frac{243}{125}

We need to find the 2nd, 3rd and 4th term of the geometric sequence.

To find these terms, we need to know the common difference.

The common difference can be determined using the formula,

a_n=a_1(r)^{n-1}

where a_1=15 and a_5=\frac{243}{125}

For n=5, we have,

\frac{243}{125}=15(r)^4

Simplifying, we have,

r=\frac{3}{5}

Thus, the common difference is r=\frac{3}{5}

Now, we shall find the 2nd, 3rd and 4th terms by substituting n=2,3,4 in the formula a_n=a_1(r)^{n-1}

For n=2

a_2=15(\frac{3}{5} )^{1}

   =9  

Thus, the 2nd term of the sequence is 9

For n=3 , we have,

a_3=15(\frac{3}{5} )^{2}

   =15(\frac{9}{25} )

   =\frac{27}{5}

Thus, the 3rd term of the sequence is \frac{27}{5}

For n=4 , we have,

a_4=15(\frac{3}{5} )^{3}

    =15(\frac{27}{25} )

    =\frac{81}{25}

Thus, the 4th term of the sequence is \frac{81}{25}

Therefore, the geometric sequence is 15,9,\frac{27}{5},\frac{81}{25},  \frac{243}{125}
