Step-by-step explanation:
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

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

and since y=1
x=2
Answer:
x = 5
Step-by-step explanation:
2x + 8 = 18
2x = 10
x= 5
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]
<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

- 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!
