$Answer: \\ Since \: \widehat{SRT} = \widehat{STR} \: \\and \: \widehat{RTU} = \widehat{STR} + \widehat{STU} = 180^{\circ} \\ \Rightarrow \widehat{SRT} + \widehat{STU} = 180^{\circ} \\ \Leftrightarrow 4x - 20 + 6x = 180 \\ \Leftrightarrow10x = 200 \\ \Leftrightarrow x = 20 \\ \widehat{SRT} = 4 \times 20 - 20 = 60^{\circ}$

liq [111]

Answer:

Step-by-step explanation:

If you replace each answer choice with the varibale, (x) then 15 would be the only choice that fits properly.

Equation:

20-x = 35-(2x)

when replacing 15 with x this is your new equation...

20-15 = 35-(2x15)

5 = 35-30

In a box of chocolates, 1/5 of the chocolates contain nuts.

uysha [10]

Answer:

Step-by-step explanation:

<u>Ratios and Fractions</u>

It's given 1/5 of the chocolates in a box contain nuts. The rest do not contain nuts. The portion that does not contain nuts is:

$1 - \frac{1}{5}=\frac{4}{5}$

We need to calculate the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts.

This can be done by dividing 1/5 by 4/5:

$\displaystyle \frac{\frac{1}{5}}{\frac{4}{5}}$

Operating:

$\displaystyle \frac{1}{5}\cdot\frac{5}{4}=\frac{1}{4}$

Expressing it as a ratio: 1:4
