Answer:

D

Step-by-step explanation:

x-3x-(-5x)

it will be easier to solve the equation in sections:

x-3x

-2x

now deal with the other part

-(-5x)

a negative multiplied by a negative equals a positive so:

+5x

now putting the parts together:

-2x+5x

3x, therefore the answer is d: 3x

Tom and Jimmy plan to leave at the same time from home and
raketka [301]

To find the distance between the homes of Tom and Jimmy, it is assumed

that the distances from their home to the café are equal.

  • The distance between Tom and Jimmy's home is \underline{1,617.\overline 7 \ meters}<u />

Reasons:

The direction in which Tom and Jimmy walks = Towards each other

The speed at which Tom walks = 52 meters per minute

The speed with which Jimmy walks = 70 meters per minute

The time at which Tom leaves = 4 minutes earlier than Jimmy

The point at which they meet = The café

The rate of their speed = Constant

Required:

The distance between Tom and Jimmy home.

Solution:

Tom and Jimmy had a plan to walk at the same speed and meet up at the café.

We have;

The café is equal distance from Tom and Jimmy's houses.

Which gives the following simultaneous equation.

52 × (4 + t) = The distance of Tom's house from the café

70 × t = The distance of Jimmy's  house from the café

  • 52 × (4 + t) = 70 × t

52 × 4 = 70 × t - 52 × t = 18 × t

\displaystyle t = \frac{52 \times 4}{18}  = \frac{104}{9} = 11.\overline{6}

The time it take Jimmy to reach the café, <em>t</em> = \mathbf{11.\overline6} minutes

The distance between their homes, d = 52 × (4 + t) + 70 × t

∴ d = 52 × (4 + 11.\overline6) + 70 × 11.\overline6 = 1,617.\mathbf{\overline 7}

  • The distance between Tom and Jimmy's home = 1,617.\overline 7 meters

Consider △RST and △RYX. If the triangles are similar, which must be true? A. RY/YS=RX/XT=XY/TS B.RY/RS=RX/RT=XY/TS C.RY/RS=RX/RT
trasher [3.6K]

Answer:

B.RY/RS=RX/RT=XY/TS

Step-by-step explanation:

If Triangles RST and RYX are similar, then the ratio of their corresponding sides is:

\dfrac{RS}{RY}= \dfrac{ST}{YX}=\dfrac{RT}{RX}\\$This could also be written by switching the numerator and denominators as:\\\dfrac{RY}{RS}= \dfrac{XY}{TS}=\dfrac{RX}{RT}

Out of the given options, Option B is true.
