Is it necessary to check for an extraneous solution for the equation below? How do you know? ( I attached the image with equation)
Answers
No, it is not is not necessary because we don't have any division by zero issues that will come up. If we had a variable in the denominator, then it would be a different story.
-----------------------
If you're curious about solving this equation, then you would first multiply both sides by the LCD 15 to clear out the fractions.
(6w-1)/5 - 3w/1 = (12w-16)/15
15*[ (6w-1)/5 - 3w/1 ] = 15*[ (12w-16)/15 ]
15*[ (6w-1)/5 ] - 15*[ 3w/1 ] = 15*[ (12w-16)/15 ]
3(6w-1) - 15(3w) = 12w-16
18w-3 - 45w = 12w-16
-27w-3 = 12w-16
-3+16 = 12w+27w
13 = 39w
39w = 13
w = 13/39
w = 1/3
To check this answer, you plug it back into the original equation. You should get the same thing on both sides when you simplify fully. Again we don't have to worry about extraneous solutions because we don't have any division by zero issues.

Problem 1
Answer: x = 60-----------------
Work Shown:
For any triangle, the three angles always add to 180.
60+60+x = 180
x+120 = 180
x = 180-120
x = 60
This triangle is considered equiangular because all angles are equal. It is also equilateral meaning all sides are the same length.
====================================================
Problem 2
Answer: x = 134-----------------
Work Shown:
We'll use the remote interior angle theorem. This is where we add two interior angles, and that sum is equal to an exterior angle that is not adjacent to any of the interior angles mentioned.
So basically we can say
x = 64+70
x = 134
If you want a longer method, then let y be the missing interior angle of the triangle. Note how 64+70+y = 180 which solves to y = 46. Then note how y+z = 180 since the angles y,z are a linear pair. That means y+z = 180 turns into 46+z = 180 which solves to z = 134.
====================================================
Problem 3
Answer: x = 36-----------------
Work Shown:
Use the remote interior angle theorem
(interior angle1)+(interior angle2) = remote exterior angle
(24) + (2x+18) = 3x+6
2x+42 = 3x+6
42-6 = 3x-2x
36 = x
x = 36

A kangaroo hops 2 kilometers in 3 minutes. At this rate, how far does the kangaroo travel in 2 minutes? *
Answers
Answer:
At a speed of 2 km every 3 minutes, in 2 minutes the kangaroo would travel 1,333 km.
Step-by-step explanation:
If a kangaroo hops 2 kilometers in 3 minutes, to calculate how much distance this animal hops in 2 minutes, the following calculation should be performed:
2 km / 3 min = 0.666 km per minute (2/3 x 2)
0.666 km per minute x 2 minutes = 1.333 kilometers in 2 minutes (0.666 x 2)
Therefore, at a speed of 2 km every 3 minutes, in 2 minutes the kangaroo would hop 1,333 km.
