Geometry problem, Fill in the two blanks with the missing angle measures for the triangle shown
Answers
Angle B= 40 Degrees
Angle A= 80 Degrees
Explanation: Angle B and 140 degrees are supplementary angles, which add up to 180 degrees because they are adjacent and form a line, 180-140 degrees is 40, so Angle B is 40 degrees. Knowing that, and that the interior of a triangle is equal to 180 degrees, we can add the two angles we already know, 60 and 40, making 100 degrees. Therefore, angle A is equal to 80 degrees. 180-100=80

Answers
Answer:
A and C
Step-by-step explanation:
Let's begin with simplifying the first expression
4x + 5x + 6 − 5x − 4
After adding and subtracting like terms, you end up with:
4x + 2
A would be a correct answer because the expression provided in that letter is the same as the original expression
B would be wrong
C would be correct too, after subtracting like terms, you end up with 4x + 2
D would be wrong
Answer:
A 4x + 2
C 9x − 5x + 2
Step-by-step explanation:
To solve;
4x + 5x + 6 − 5x − 4
Collect like terms,
4x+5x-5x+6 - 4
9x-5x+2

How many solutions does the equation 10k-10k= 0 have? No solution,one solution,or infinite solutions?
Answers
Answer:
infinitely many
Step-by-step explanation:
You want to know the number of solutions to the equation 10k -10k = 0.
IdentityThe given equation can be simplified to ...
0 = 0
It is true no matter what value is chosen for k. It has infinitely many solutions.
<95141404393>
The equation 10k - 10k = 0 has infinitely many solutions.
The equation 10k - 10k = 0 can be simplified as 0 = 0.
In this case, the variable "k" is eliminated from the equation, and we are left with a true statement that states 0 is equal to 0. This equation is an example of an identity, where both sides of the equation are always equal, regardless of the value of "k".
Since the equation is true for any value of "k", it means that any value of "k" would satisfy the equation. Therefore, this equation has infinitely many solutions.
When we have an equation with the same term on both sides that can be simplified to a true statement, it means that the equation is an identity. In this particular case, no matter what value we substitute for "k", the equation will always hold true.

GIven :
A student concluded that 8x - 12 = 4( 1/2x - 6 ) has infinity many solutions.
The following steps can be used in order to determine the statement that describes the student's conclusion:
Step 1 - Write the given linear equation.
[tex]8x - 12 = 4 (\dfrac{1}{2}x-6)[/tex]
Step 2 - Simplify the above equation.
8x - 12 = 2x - 24
Step 3 - Subtract 2x on both sides in the above equation.
8x - 2x - 12 = 2x - 2x - 24
6x - 12 = -24
Step 4 - Add 12 on both sides in the above equation.
6x - 12 + 12 = 12 - 24
6x = -12
Step 5 - Divide by 6 on both sides in the above equation.
x = -2
Therefore, the correct option is B) The conclusion is incorrect because there is exactly one solution to the equation.
