Answer:

\large\boxed{10\dfrac{1}{2}\cdot15\dfrac{1}{8}=158\dfrac{13}{16}}

Step-by-step explanation:

Convert the mixed numbers to the improper fractions:

10\dfrac{1}{2}=\dfrac{10\cdot2+1}{2}=\dfrac{21}{2}\\\\15\dfrac{1}{8}=\dfrac{15\cdot8+1}{8}=\dfrac{121}{8}

Now we can multiply:

10\dfrac{1}{2}\cdot15\dfrac{1}{8}=\dfrac{21}{2}\cdot\dfrac{121}{8}=\dfrac{(21)(121)}{(2)(8)}=\dfrac{2541}{16}=158\dfrac{13}{16}

Other method.

You can convert to the decimal:

10\dfrac{1}{2}=10.5\\\\15\dfrac{1}{8}=15.125

And do the multiplication on decimals (can use a calculator):

10.5\cdot15.125=158.8125

Triangles WSR and TVR are similar. Find x.
Vlad [161]

They are similar. Set the proportions equal to each other

(x + 8)/8 = (x+14)/12

Cross multiply

(x + 8)/8 (8)(12) = (x + 14)/12 (12)(8)

12(x + 8) = 8(x + 14)

Distribute the 12 and 8 to the corresponding monomials inside the parenthesis

12(x + 8) = 12x + 96

8(x + 14) = 8x + 112

12x + 96 = 8x + 112

Isolate the x. Subtract 8x from both sides and 96 from both sides

12x (-8x) + 96 (-96) = 8x (-8x) + 112 (-96)

12x - 8x = 112 - 96

4x = 16

Isolate the equal sign. Divide 4 from both sides

4x/4 = 16/4

x = 16/4

x = 4

------------------------------------------------------------------------------------------------------------------

4 is your answer for x
