Question:

The first side of a triangle is four inches longer than twice the

second side. The third side of the triangle is 5 inches shorter than

the sum of the other two sides. The perimeter is 72 inches. Find

the lengths of the three sides.

Answer:

The sides of the triangle are: 11.5, 27 and 33.5

Step-by-step explanation:

Let the first side be f, the second be s and the third be t.

So, we have:

[tex]f =4 + 2s[/tex]

[tex]t = f + s - 5[/tex]

[tex]Perimeter = 72[/tex]

Required

Determine the length of the three sides

Perimeter is calculated as:

[tex]Perimeter = f + t + s[/tex]

Substitute values for f and t

[tex]Perimeter = 4+2s + f+s-5 + s[/tex]

[tex]Perimeter = f+2s +s+s-5+4[/tex]

[tex]Perimeter = f+4s-1[/tex]

Substitute values for f and Perimeter

[tex]72 = 4+2s+4s-1[/tex]

[tex]72 = 2s+4s-1+4[/tex]

[tex]72 = 6s+3[/tex]

Collect Like Terms

[tex]6s = 72 -3[/tex]

[tex]6s = 69[/tex]

[tex]s= 11.5[/tex]

[tex]f =4 + 2s[/tex]

[tex]f = 4 + 2 *11.5[/tex]

[tex]f = 27[/tex]

[tex]t = f + s - 5[/tex]

[tex]t=27+11.5 - 5[/tex]

[tex]t=33.5[/tex]

The sides of the triangle are: 11.5, 27 and 33.5

Answer:

22

Step-by-step explanation:

If x = 5, then plug 5 in for x .

3(5) + 7

15 + 7 = 22

Answer:

22

Step-by-step explanation: 3x + 7

3*5 = 15

15+7=22

Answer:

Angles forming a linear pair are supplementary and sum to 180°

The smaller angle is 20°

A(-2, 10) reflected over x-axis

Rule for such a reflection is:

Point A will map to:

Correct option is D

One point is at the origin and two other points are at the distance m horizontally and vertically from the origin

The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:

Answer:you paid less for the bottle this week and it was $0.44 cheaper than last week

Step-by-step explanation:

hope this helps !

Answer:

You paid 0.89 cents less (also, is that schoology? just curious because thats what i use :))

Step-by-step explanation:

1 last week= $1.69

1 this week= 4÷$5 = 0.8 cents

You paid less for the bottle this week.

So you paid 0.89 cents less

Answer:

  (B)

Step-by-step explanation:

x is on the left side of the < symbol, so the shaded portion of the line will be on the left side of the boundary dot.

The boundary dot is plotted at the constant, which is 1/2 = 2/4. That plot is shown in selection B.

_____

Additional comment

I like to write inequality solutions using the < or ≤ symbols because the relative positions of numbers and variables match their relative positions on the number line. In this problem, we have x < 1/2, so the shaded portion of the line is on the left of the boundary dot, just as x is on the left of 1/2 in the inequality.

Answer:

The answer is 6.5 hours.

Step-by-step explanation:

If you multiply the hours need to work during that week days(6) and the hours worked during the weekend(3.5) you get 33.5 hours worked over all. then, you subtract 40(the hours wanted) and 33.5(the hours worked normally) and you get 6.5.

Answer:

aproximately 23.5 I believe

Step-by-step explanation:

ok, so first you square 17, which is 289. then you square 29, which is 841. subtract 289 from that:

841-289=552

now take the square root of 552

aproximately 23.5 I believe

Answer:  23cm

Step-by-step explanation:

a² + b² = c²

x² + 17² = 29²

x² + 289 = 841

x²  = 552

√x²  = √552

x  ≈ 23 cm

Answer:

yes because the gift has a surface area of 48 square inches

Step-by-step explanation:

Surface area formula:

A = 2(wl + hl + hw)

2 · (4 · 4 + 1 · 4 + 1 · 4) = 48

Answer:

2.9 to the 4th power

Step-by-step explanation:

Answer:

8 m = width

28 m = length

Step-by-step explanation:

Let w = width

3w + 4 = length

P =  2w + 2l

  = 2w + 2(3w + 4) = 72

     2w + 6w + 8 = 72

      8w + 8 = 72

       8w = 64

         w = 8 m = width

3w + 4 = 24 + 4 = 28 m = length
