Answer:
[tex]x=11[/tex]
Step-by-step explanation:
The sum of all the angles in a triangle is always 180 degrees.
Hence,
[tex](7x-17)+42+78=180[/tex]
Remove the brackets:
[tex]7x-17+42+78=180[/tex]
Add/Subtract the numbers:
[tex]7x+103=180[/tex]
Subtract 103 from both sides:
[tex]7x+103-103=180-103[/tex]
[tex]7x=77[/tex]
Divide both sides by 7:
[tex]\frac{7x}{7}=\frac{77}{7}[/tex]
[tex]x=11[/tex]
Answer:
X = 11
Step-by-step explanation:
This triangle will add up to 180 degrees
Our angles we have right now our 42 and 78 I add those up so I know how much the missing angle will have to equal to add up with the others to equal 180 so 42 + 78 = 120
So our other angle will have yo equal 60 so we have to find out what multiplied by 7 subtracted by 17 equals 60 well 7 x 11 = 77 and 77 - 17 = 60 so x = 11

Let f(x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
Select the correct response:
f(x) – g(x) = 7x + 1
f(x) – g(x) = 3x – 5
f(x) – g(x) = 7x – 1
f(x) – g(x) = -3x + 5
Answers
Answer:
f(x) - g(x) = 3x - 5
Step-by-step explanation:
Hi,
To subtract f(x) and g(x), we need to do (5x - 2) - (2x + 3). We solve and we get 3x - 5. So, f(x) - g(x) = 3x - 5.
The second answer choice is correct.

A bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow. A marble is drawn at random. What is the probability that it is not yellow.
Answers
Answer:
There is a 9/10 probability that the marble will not be yellow.
Step-by-step explanation:
If there are a total of ten marbles, and there is one yellow marble, there is a
1 yellow marble / 10 total marbles chance of getting a yellow marble. Then subtract it from 10/10 to get the probability of NOT getting a yellow marble.
10/10 - 1/10 = 9/10.

Describe lengths of three segments that could not be used to form a triangle. Segments with lengths of 5 in., 5 in., and ______ in. Cannot form a triangle.
Answers
Answer:
[tex]c = 11[/tex]
Step-by-step explanation:
Given
Let the three sides be a, b and c
Such that:
[tex]a = b= 5[/tex]
Required
Find c such that a, b and c do not form a triangle
To do this, we make use of the following triangle inequality theorem
[tex]a + b > c[/tex]
[tex]a + c > b[/tex]
[tex]b + c > a[/tex]
To get a valid triangle, the above inequalities must be true.
To get an invalid triangle, at least one must not be true.
Substitute: [tex]a = b= 5[/tex]
[tex]5 + 5 > c[/tex] [tex]===>[/tex] [tex]10 > c[/tex]
[tex]5 + c > 5[/tex] [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]
[tex]5 + c > 5[/tex] [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]
The results of the inequality is: [tex]10 > c[/tex] and [tex]c > 0[/tex]
Rewrite as: [tex]c > 0[/tex] and [tex]c < 10[/tex]
[tex]0 < c < 10[/tex]
This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)
Any value outside this range, cannot form a triangle
So, we can say:
[tex]c = 11[/tex], since no options are given
