Answer:
137 degrees
Step-by-step explanation:
in the triangle with 60 degrees : the top angle must be also 45 degrees (the same as the angle above it).
then its third angle must be 180 - 60 - 45 = 75 degrees (because the sum of all angles is always 180 degrees in any triangle).
then the sum of this 75 degrees angle, then the neighboring 68 degree angle and the next one (the left angle in the triangle with 100 degrees) together must be again 180 degrees, because all angles around a point on one side of a line are 180 degrees (a half circle).
that means this left angle of the 100 degrees triangle is
180 - 75 - 68 = 37 degrees.
that means that the right angle of the 100 degrees triangle is
180 - 37 - 100 = 43 degrees (again, because of the sum in a triangle).
and now that gives us the ? angle as
180 - 43 = 137 degrees
because this is again the sum around s point on a line (the line is the arrow line starting at the 100 degrees angle pointing leading and pointing to the bottom right).

Solve and graph x - 2 > -5 and x - 2 < 4 on a number line
Answers
Answer:
(-3, 6)
Step-by-step explanation:
Solve x - 2 > -5 for x as follows: Add 2 to both sides, obtaining x > -3. To graph this, find -3 on the number line and put a circle there. Draw a solid line from this circle towards the right.
Solve x - 2 < 4 for x as follows: Add 2 to both sidees, obtaining x < 6. Find 6 on the number line and put a circle there. Draw a solid line from this circle to the left.
Notice that the two lines you've drawn overlap on the interval (-3, 6). This is the desired solution set.

Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double time rate. Her gross pay was $734.40. What was her hourly rate?
Answers
Answer:
15.30 per hour
Step-by-step explanation:
The hourly rate for Mr Frasier will be $15.30.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double-time rate. Her gross pay was $734.40.
The hourly rate will be calculated as:-
Rate = 40 + 2 x 4 = 734.40
Rate = 40 + 8 = 734.40
Rate = 734.40 / 48
Rate = $15.3
The hourly rate is $15.3.

The state fair is a popular field trip destination. This year the senior class at High School A and
the senior class at High School B both planned trips there. The senior class at High School A
rented and filled 1 van and 3 buses with 80 students. High School B rented and filled 14 vans
and 1 bus with 218 students. Each van and each bus carried the same number of students. Find
the number of students in each van and in each bus.
Answers
Answer:
each bus carries 22 students
each van carries 14 students
Step-by-step explanation:
1v+3b=80
14v+b=218
eliminate b by multiplying the bottom equation by 3.
(42v+3b=654)-(1v+3b=80)=
41v=574
divide both sides by 41
v=14 (each van carries 14 students)
substitute the value of v into either of the og equations
1(14)-14+3b=80-14
3b=66
divide both sides by 3
b=22 (each bus carries 22 students)

Consider the linear function f(x) = 3x-1. Find f(0), f(1), f(2)
Answers
Answer:
f(0) = -1, f(1) = 2, f(2) = 5.
Step-by-step explanation:
f(0) = 3(0) - 1 = -1
f(1) = 3(1) - 1 = 2
f(2) = 3(2) - 1 = 5
The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = 3x + 1
The value of the function at x = 0 will be
f(0) = 3(0) + 1
f(0) = 0 + 1
f(0) = 1
The value of the function at x = 1 will be
f(1) = 3(1) + 1
f(1) = 3 + 1
f(1) = 4
The value of the function at x = 2 will be
f(2) = 3(2) + 1
f(2) = 6 + 1
f(2) = 7
The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

which inequality is true when the value of w is 13 w-<5 -w-3>-5 -w-3>5 w->5
Answers
w > -5 shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true
We need to get the equation that is true for w to be 13. This means that the required inequality expression should be w must be a positive integer.
For the Expression -w - 3 > -5
-w > -5 + 3
-w > -2
w < 2
Since w is less than 2, hence the inequality is wrong
For the inequality
-w - 3 > 5
-w > 5 + 8
-w > 13
w < -13
Since w < -13, hence the inequality is wrong
For the inequality w > -5
It shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true
