Answer:
x=95 degrees
Step-by-step explanation:
All of the angles in a triangle add up to 180, so 45+50+(180-x)=180.
Open the parenthesis, and you get 45+50+180-x=180.
Then subtract 180 from both sides, so 45+50-x=0.
Simplify that to 95-x=0, and add x to both sides.
x=95
Also, you can use exterior angles theorem, which states that 45+50=x.
That's the shorter way.

Find the value of d so the line that passes through (a,b) and (c,d) has a slope of 12.
Answers
Answer:
d = 12c-12a+b
Step-by-step explanation:
The formula for calculating the slope of a line passing through two points (x1, y1) and (x2, y2)is expressed as:
m = y2-y1/x2-x1
Given the coordinates (a,b) and (c,d) and slope m = 12
Substitute into the formula as shown:
m = d-b/c-a
12 = d-b/c-a
Make d the subject of the formula:
12 = d-b/c-a
cross multiply
12(c-a) = d-b
12c-12a = d-b
add b to both sides
12c-12a + b = d-b+b
12c-12a + b = d
Hence d = 12c-12a+b

Let us analyze each of the students expression and determine the correct one if there are any.
Chang expression after factoring: 4-3(3x+7)
In order to know whether chang's factorization is similar to the expression, we will expand and compare with the given expression as shown;
= 4-3(3x+7)
Open the parenthesis
= 4 - 3(3x)-3(7)
= 4 - 9x - 21
This shows that Chand expression is wrong.
Hence Chang expression is not an equivalent expression because when -3 is factored out from the bracket, it supposed to leave a negative sign instead of positive.
Benjamin expression after factoring: 4+3(3x+7)
In order to know whether Benjamin's factorization is similar to the expression, we will expand and compare with the given expression as shown;
= 4+3(3x+7)
Open the parenthesis
= 4 + 3(3x)+3(7)
= 4 +9x + 21
This shows that Benjamin expression is wrong.
Hence Benjamin expression is not an equivalent expression because the positive values within the expression is supposed to be negative sign instead
Habib expression after factoring: 4+12x
The equation is obviously wrong and not an equivalent expression because the constant value 21 does not have a variable x and cannot be added to -9x according to what Habib did.
Given the expression
4 - 9x + 21
The correct simplification of the expression is as shown;
4 - 3(3x - 7)
Note that when -3 is factored out, the sign inside the parenthesis also changes

So you do -1*7 which is -7 and -1*-4x, which is 4x. So you then have -7+4x. Then you add 7 to both sides, getting 4x equals 16. You divide both by 4, making x=4

Gary applied the distributive property using the greatest common factor to determine the expression that is equivalent to 66 + 36. His work is shown below. Factors of 66: 1, 2, 3, 6, 11, 22, 33, 66 Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36 66 + 36 = 3 (22 + 12)
Answers
Step-by-step explanation:
Factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
GCF (greatest common factor) = 6
Gary applied the distributive property using the greatest common factor to determine the expression that is equivalent to 66 + 36. He wrote it as :
66 + 36 = 3 (22 + 12)
But he is wrong. He multiplied (22+12) by 3 which is wrong. The correct step should be :
66 + 36 = 6 (11+ 6)
= 6(17)
= 102
Hence, this is the required solution.

Last year, 320 students were members of Pine Hill Middle School clubs. This year, there was a 20% increase in memberships. How many students are members this year?
Answers
Answer:
384
Step-by-step explanation:
No. of students in the club last year = 320
No. of students in the club this year increased by 20%
To find the actual increase, 20% is multiplied by the number of students in the club last year which is 320 and to find the number of students in the club this year add the answer to 320 (the number of students in the club last year)
That is,
= 20% * 320
= 20/100 * 320
= 64
Finding the number of students in the club this year
320 + 64 = 384 students
NOTE : Increase means addition that is why the number of students in the club last year is added to the actual increase

4(2q – 3) = 8q-12
Pls solve and show steps
Answers
Answer:
LHS = RHS = -12
Step-by-step explanation:
=> 4(2q - 3 ) = 8q - 12.
=> 8q - 12 = 8q - 12 .
=> 8q - 8q - 12 = -12 .
=> -12 = -12 .
Hence LHS = RHS .
[tex]4(2q - 3) = 8q - 12[/tex]
[tex]8q - 12 = 8q - 12[/tex]
[tex]8q + - 12 = 8q + - 12[/tex]
[tex] - 12 - 8q = - 12 - 8q[/tex]
[tex] - 12 = - 12[/tex]
[tex] - 12 + 12 = - 12 + 12[/tex]
[tex]0 = 0[/tex]
By the above equation , we can conclude that any real number can be placed in the place of q to make the left hand side of the equation become equal to the right hand side of the equation .
Therefore , any real number ( integer , fraction and rational number ) can be placed in the place of q .

Describe the end behavior of the graph f(x) using limits.
Answers
Answer:
um
Step-by-step explanation:
The end behavior of the graph f(x) using limits are
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
Option B is the correct answer.
We have,
From the graph,
As the x-value increases, the function y-values goes to -∞.
As the x-value decreases, the function y-values goes to -∞.
Now,
f(x) is the y-value.
The end behavior of the graph f(x) using limits can be represented as,
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
Thus,
The end behavior of the graph f(x) using limits are
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
