One side of triangle is 3x -5.. the other side is 19-x and the base is 2x. What is the perimeter of the triangle
Answer:
4x+14
Step-by-step explanation:
In order to find the perimeter of an triangle you need to add up all the sides of the triangle.
3x-5+19-x+2x ---> 3x+14-x+2x --> 4x+14

Find the unknown length y in the pair of similar triangles.
Similar triangles have a scale factor that determine the length of each side.
15 / 7.5 = 2
The scale factor = 2
17 / 2 = 8.5
y = 8.5

Answer:
x = 21°
Step-by-step explanation:
opposite angles are equal
therefore, (3x + 1)° = 64°
open the brackets
3x + 1 = 64
3x = 64 - 1
3x = 63
divide both sides by 3
x = 21°
On the map, the school and the sports park are 12 centimeters apart.
What is the actual distance between the school and the park?
Answer:
15 kmStep-by-step explanation:
On the map, the school and the sports park are 12 centimeters apart.
scale 4cm : 5km
find;
What is the actual distance between the school and the park?
solution:
12 cm = 4 cm
X km 5 km
cross multiply:
4 cm X km = 12 cm (5 km)
X = 12 cm (5 km)
4 cm
X = 15 km
therefore, the distance between the school and the sports park is 15 km
Help solve step by step please? 3/7➗4/5=
Answer:
15/28
Step-by-step explanation:
Step-by-step explanation:
3/7 divided by 4/5
Find the reciprocal of 4/5 which is 5/4
Multiply 3/7 by 5/4
3*5= 15 which is the numerator
7*4=28 which is the denominator
so the final answer is 15/28
Find the slope, if it exists, of the line containing
(-8,-5) and (-19,- 13)
Answer: 8/11
Step-by-step explanation:
To find slope you can use this formula:
y2-y1/x2-x1
substitute the values with the ones from the 2 points
-13-(-5)= -8
-19-(-8)=-11
you then divide -8/-11
and you get 8/11
8/11 is the slope of those 2 points.

Step-by-step explanation:
Amtrail trains provide efficient, nonstop transportation between Los Angeles and San Diego. Train A leaves Los Angeles headed toward San Diego at the same time that Train B leaves San Diego headed for Los Angeles, traveling on parallel tracks. Train A travels at a constant speed of 84 miles per hour. Train B travels at a constant speed of 92 miles per hour. The two stations are 132 miles apart. How long after they leave their respective stations do the trains meet
Answer:
0.75 hour or 45 mins
Step-by-step explanation:
From the question, we are told that:
Speed of Train A = 84 miles per hour. Speed of Train B = 92 miles per hour.
Total speed travelled by both trains =
84mph + 92mph
= 176 mph
The distance between the two stations = 132 miles.
We are asked in the question to: find out how long after they leave their respective stations do the trains meet.
This means we should calculate the time
Time = Distance/ Speed
= 132 miles/176 miles per hour
= 0.75 hour
We can convert to minutes if we like
1 hour = 60 minutes
0.75 hour =
0.75 hour × 60 minutes/ 1 hour
= 45 minutes
Therefore, the trains meet after 0.75 hour or 45 minutes after they have left their respective stations.
what’s.the perimeter of a square with an area of 49 cm2
Answer:
28Step-by-step explanation:
Area of a square =
[tex]s^2[/tex]
Perimeter =
[tex]4\times s[/tex]
Where s = side
Solve for s using the area
[tex]A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7[/tex]
Find the perimeter
[tex]4\times s\\\\= 4 \times 7\\\\= 28[/tex]

Answer:
37
Step-by-step explanation:
180-(81+62)=37
Answer:
x = 37°
Step-by-step explanation:
The sum of all internal angles in a triangle will always equal 180.
Thus, we know that 81 + 62 + x must equal 180.
81 + 62 + x = 180
143 + x = 180
Subtract 143 from both sides:
x = 180 - 143
x = 37
Answer: x = 37°
Which statement about the graph is true? 7 6 5 2 3 2 1 1 2 3 4 5 6 7 8 x O The graph shows a proportional relationship because it is a line, and the difference between each point is the same. The graph shows a proportional relationship because it is a line, and each x-value isha multiple of 2. O The graph does not show a proportional relationship because each point written as a ratio gives a different value.
Answer:
I think but it can also be the first one
The graph shows a proportional relationship because it is a line, and each x-value isha multiple of 2.

Can anyone help me with my algebra homework ?
Answer: No, it is not possible
Why not? Because of the phrasing "share an arm AB". If two angles share a common line, segment or ray, then they are considered adjacent angles by definition. You can think of two rooms sharing the same wall. Those rooms are adjacent. So we cannot have nonadjacent angles sharing the same arm AB.
