Find the value of x.

lawyer [7]

Answer:

$\huge\boxed{x=\sqrt{70}}$

Step-by-step explanation:

ΔABC and ΔADB are similar (AAA).

Therefore the corresponging sides are in proportion:

$\dfrac{AB}{AD}=\dfrac{AC}{AB}$

Substitute:

$AB=x\\AC=7+3=10\\AD=7$

$\dfrac{x}{7}=\dfrac{10}{x}$ <em>cross multiply</em>

$(x)(x)=(7)(10)\\\\x^2=70\to x=\sqrt{70}$

Tommy has three times as many video games as Griffin. Fletcher has eight less than Tommy. The total number of video games is les

zimovet [89]

Answer:

x = 6.86

Number of video games Fletcher has = 12.58

Step-by-step explanation:

Let

Number of video games Griffin has = x

Number of video games Tommy has = 3x

Number of video games Fletcher has = 3x - 8

Total number of video games is > 40

Griffin + Tommy + Fletcher > 40

x + 3x + (3x - 8) > 40

4x + 3x - 8 > 40

7x > 40 + 8

7x > 48

x > 48 / 7

x > 6.86

Number of video games Fletcher has = 3x - 8

= 3(6.86) - 8

= 20.58 - 8

= 12.58
