Answer:

  8 ft

Step-by-step explanation:

Let t represent the length of the third side. The first side is 7 ft more, so is (t +7). The second side is 1 ft shorter than 3 times the third side, so is (3t -1). The perimeter is the sum of the side lengths:

  21 = (t +7) +(3t -1) +t

  21 = 5t +6

  15 = 5t . . . . . . . subtract 6

  3 = t . . . . . . . divide by 5

Then the length of the second side is ...

  3t -1 = 3·3 -1 = 8 . . . . feet

The length of the second side is 8 feet.

_____

<em>Additional comment</em>

The first side is 3+7 = 10 ft. So the three side lengths are 10 ft, 8 ft, 3 ft.

Does anyone know what to fill in?

Answer:

$36.69

Step-by-step explanation:

Okay, so let's first write the equation:

2.59*10 + 3d = 135.97

Now, let's work on isolating d by first simplifying the equation:

25.9 + 3d = 135.97

25.9 + 3d - 25.9 = 135.97 - 25.9

3d = 110.07

3d/3 = 110.07/3

d = 36.69

Okay, now let's check:

2.59*10 + 3*36.69  = 135.97

25.9 + 110.07 = 135.97

135.97 = 135.97

Okay, so so it costs $36.69 per pair of shoe.

If you were given a fractional strip, that did not have any subdivisions marked like this one pictured below, how would you dete
Pavlova-9 [17]

Answer:

  it depends on the accuracy and resolution required of the answer

Step-by-step explanation:

The shaded portion appears to be about half the length of the unshaded portion, suggesting the shaded amount is 1/3.

__

Using a pair of dividers, one could determine the number of times the shaded portion fits into the whole bar. Depending on how much is left over, the process could repeat to determine the approximate size of the remaining fraction relative to the bar or to the shaded portion. (Alternatively, one could replicate the length of the bar to see what integer number of shaded lengths fit into what integer number of whole lengths.)

One could measure the shaded part and the whole bar with a ruler, then determine the relative size of the shaded part by dividing the first measurement by the second. The finer the divisions on the ruler, the better the approximation will be.
