165 Ting Ting's beads* (4 Sherrie's beads/ 5 Ting Ting's beads)= 132 Sherrie's beads.
132 Sherrie's beads* (1 Roxanne's bead/ 2 Sherrie's beads)= 66 Roxanne's beads.
Now that we know the number of beads Roxanne and Ting Ting have, let's subtract:
165 beads- 66 beads= 99 beads.
Hope this would help :))

R=1/2S    (names abbreviated)
S= 4/5T
T=165 beads
S= 4/5X 165           S=132
R= 1/2X 132              R=66

165 beads-66 beads= 99 beads  R has 99 more beads than TT

Given a dilation around the origin, what is the scale factor K?
kobusy [5.1K]

Answer:

The answer is "\frac{4}{3}"

Step-by-step explanation:

Given:

\bold{DoK = (12, 8) (9,6)}

In the scale factor when we take x coordinate then the value of k is:

\Rightarrow x= \frac{x_1}{x_2}\\\\\Rightarrow x= \frac{12}{9}\\\\\Rightarrow x= \frac{4}{3}\\

If we take y coordinate then the value of k is:

\Rightarrow y= \frac{y_1}{y_2}\\\\\Rightarrow y= \frac{8}{6}\\\\\Rightarrow y= \frac{4}{3}\\

So, the final value of k is "\frac{4}{3}" .

Answer:

x=20; y=50 or (20, 50)

Step-by-step explanation:

Substitution means plugging in one variable's value that consists of the opposite variable. Because y=3x-10 is already specified, you can plug it into the second equation's y value. After doing that, it looks like this:

-4x+2y=20→-4x+2(3x-10)=20

Then you would distribute the 3 across the parentheses next to it, like this:

-4x+2(3x-10)=20→-4x+6x-20=20

Then, add like terms, like this:

-4x+6x-20=20→2x=40

Then divide both side by 2 to isolate x.

x=20

Now, you can plug 20 (x) into either equation, but the first one seems simpler so you would pick that. It would look like this:

y=3x-10→y=3(20)-10

Solving would look like this:

y=3(20)-10→y=60-10→y=50

So the answer is x=20; y=50 or (20, 50).

Explanation below.

Step-by-step explanation:

1. a. \sqrt{x} =12

  b. \sqrt{x} ^{2}=12^{2}

  c. x=144

2. a. \sqrt{x^{2} } =\sqrt{196}

   b. x= 14

3.  

\sqrt{x} -4 +4= 8+4\\\sqrt{x} =12\\x= 3.46410161514  \\or  \\2\sqrt{3}

4.

2(x^{2} +3)=398\\x^{2} +3= 199\\x^{2} =196\\x=14
