Write as an equation:
Alecsey [184]

Answer: 1) 132 and 32

               \bold{2) \dfrac{340}{3} and \dfrac{20}{3}}

<u>Step-by-step explanation:</u>

Let x represent the larger number and y represent the smaller number.

*******************************************************************************************

1)

           x + y = 164     and     x = 3y + 36

(3y + 36) + y = 164

       36 + 4y = 164

               4y = 128

                 y =  32     and      x = 3(32) + 36

                                              x =   96   + 36

                                              x =       132

*******************************************************************************************

2)

          x + y = 120     and      \dfrac{4x}{2y}=34  ⇒   4x = 68y  ⇒   x = 17y

     (17y) + y = 120

             18y = 120

                y=\dfrac{120}{18}

                y=\dfrac{20}{3}    and    x=17 \bigg( \dfrac{20}{3} \bigg)

                                            x= \dfrac{340}{3}

Is 4x - 3 = 19 true, false, or open?
Artyom0805 [142]

<u>This is an open statement.</u> Because we do not know the value of x, we cannot determine if the statement is true or false.

Based on the data in this two-way table, if a flower is picked at random, what is the probability of getting a yellow flower? Ty
garik1379 [7]
If what I'm reading is correct, there are, in total, 135 yellow flowers. Since the sample space is only the color of flowers, we do not need any additional information except the total amount of flowers there are, as this is the amount that we are taking the yellow flowers from. The total amount of flowers is 315. To find our answer, divide the amount of yellow flowers by the total amount of flowers:

135 divided by 315 = 0.49

Therefore, your answer would be 0.49

Hope this helps!

Which expression is equivalent to 6–3?
Bond [772]

Your question is not well presented. See complete question below

Which expression is equivalent to 6^{-3}?

A) –63

B) 36

C) \sqrt[3]{6}

D) (\frac{1}{6} )^3

Answer:

The equivalent of 6^{-3 is (\frac{1}{6} )^3

Step-by-step explanation:

Given

Expression: 6^{-3}

Required:

Find the Equivalent Expression

To find the equivalent of this expression, we make use of law of indices.

One of the laws of indices states that

a^-b = \frac{1}{a^b}

If we apply this law to the expression above (6^{-3})

By comparison a = 6 and b = 3.

So, 6^{-3} becomes

6^{-3} = \frac{1}{6^3}

Simplifying further;

\frac{1}{6^3} = \frac{1}{6 * 6 * 6}

This can also be written as

\frac{1}{6^3} = \frac{1*1*1}{6 * 6 * 6}

By splitting the above expression; we have that

\frac{1}{6^3} = \frac{1}{6} * \frac{1}{6} * \frac{1}{6}

Multiplication law of indices states that;

a * a * a = a³. (Because they have the same base of a)

So, \frac{1}{6} * \frac{1}{6} * \frac{1}{6} can then be written as (\frac{1}{6} )^3

Hence,  \frac{1}{6^3} = (\frac{1}{6} )^3

So, the equivalent of 6^{-3} is (\frac{1}{6} )^3
