Someone solve this for me please
Butoxors [25]

Answer:

x=2; y=1

Step-by-step explanation:

Since the triangle is equilateral, which means three sides have the same length.

So we have:4x-y=2x+3y=7

4x-y=2x+3y\\4x-y+y=2x+3y+y\\4x=2x+4y\\2x=4y\\x=2y\\

Since 2x+3y=7 and plug in x=2y

we have

2x+3y=7\\2(2y)+3y=7\\4y+3y=7\\7y=7\\y=1

and since y=1

x=2

Find the missing side length of the triangie.<br> 12 in.<br> 35 in.
OlgaM077 [116]

Answer:

37

Step-by-step explanation:

Right Scalene Triangle

Side a = 37

Side b = 12

Side c = 35

Angle ∠A = 90° = 1.5708 rad = π/2

Angle ∠B = 18.925° = 18°55'29" = 0.3303 rad

Angle ∠C = 71.075° = 71°4'31" = 1.2405 rad

C=71.075°B=18.925°A=90°b=12a=37c=35

Area = 210

Perimeter p = 84

Semiperimeter s = 42

Height ha = 11.35135

Height hb = 35

Height hc = 12

Median ma = 18.5

Median mb = 35.51056

Median mc = 21.2191

Inradius r = 5

Circumradius R = 18.5

Vertex coordinates: A[0, 0] B[35, 0] C[0, 12]

Centroid: [11.66667, 4]

Inscribed Circle Center: [5, 5]

Circumscribed Circle Center: [17.5, 6]

Emily is 4 times as old as Tiffany. In ten years time, Emily will be twice as old as Tiffany . Find their ages.​
Sholpan [36]
<h3><u>Question</u><u>:</u></h3>

Emily is 4 times as old as Tiffany. In ten years time, Emily will be twice as old as Tiffany. Find their ages.

<h3><u>Solution</u><u>:</u></h3>
  • Let the age of Tiffany be x years.
  • Then, the age of Emily = 4x years.
  • After 10 years, the age of Tiffany will be (x+10) years.
  • After 10 years, the age of Emily will be (4x+10) years.
  • Therefore, by the problem

4x + 10 = 2(x + 10) \\  = 4x + 10 = 2x + 20 \\   = > 4x - 2x = 20 - 10 \\  =  > 2x = 10 \\  =  > x =  \frac{10}{2}  \\  =  > x = 5

  • So, Tiffany's present age = 5 years.
  • Emily's present age = (4×5) years = 20 years.
<h3><u>Answer:</u></h3>

Emily's age is 20 years and Tiffany's age is 5 years.

Hope it helps!
