For the first one on the left, you need to evaluate the expressions inside the parenthesis. For Question number 6, evaluate the exponent first.

Step-by-step explanation:

Think of PEMDAS, order of operations.

Parenthesis

3/4 (x - 3) - 5 = 1/8 ( x - 1 )

Answer:

x = - $\frac{57}{5}$

Step-by-step explanation:

$\frac{3}{4}$ (x - 3) - 5 = $\frac{1}{8}$ (x - 1)

Multiply through by 8 to clear the fractions

6(x - 3) - 40 = x - 1 ← distribute parenthesis and simplify left side

6x - 18 - 40 = x - 1

6x - 58 = x - 1 ( subtract x from both sides )

5x - 58 = - 1 ( add 58 to both sides )

5x = - 57 ( divide both sides by 5 )

x = - $\frac{57}{5}$

Answer:

80 degrees

Step-by-step explanation:

one half of the circle makes a straight line and that will equal 180 degrees so 60+45=105

180-105=80

so the missing angle is x=80

Check the picture below.

thus then

$\bf \begin{cases}
y=100-a\\
y=a\sqrt{3}
\end{cases}\implies 100-a=a\sqrt{3}\implies 100=a+a\sqrt{3}
\\\\\\
100=a(1+\sqrt{3})\implies \boxed{\cfrac{100}{1+\sqrt{3}}=a}
\\\\\\
\textit{what is the altitude \underline{y} then?}\qquad y=100-a
\\\\\\
y=100-\cfrac{100}{1+\sqrt{3}}\implies y\approx 63.39745962156~yards$
