Answer:

x = 3.5

Step-by-step explanation:

3.5 x 3 is 10.5. Triangle two has been expanded each side by 1.5. So multiply 7 (the side with 3x on the other triangle) x 1.5 to get 10.5. To fid x divide 10.5 by 3. This gives you 3.5 as x.

Hope it helps!

Answer:

x = 3.5

Step-by-step explanation:

What we know that the scale factor is 1.5 going from DEF to XYZ (4.5/3 = 1.5; 7.5/5 = 1.5)

So, multiply 7 by 1.5 to get ZX's length. It would be 10.5 units long.

We now know the equation, which is 3x = 10.5

3x = 10.5

<em>Cancel out the multiplication by dividing both sides by 3</em>

x = 10.5/3

<em>Divide 10.5 by 3 to get 3.5</em>

x = 3.5 in this case.

Dont understand this question it confucing

So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4.  So she's 75% of the time effective.

Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.

Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.

so, which fraction is highest 3/4, or 2/3 or 2/3?  neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.

so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.

\bf 12\cdot \cfrac{3}{4}\implies \boxed{9}\qquad \qquad 12\cdot \cfrac{2}{3}\implies \boxed{8}

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
