Step-by-step explanation:
Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30

Step-by-step explanation:
Given equation:

To find the angle measure of
Solution:
In order to find the angle measure
, we will isolate
on left side by carrying out math operations on both sides.
We have:

Subtracting both sides by


Subtracting both sides by 1°.

Dividing both sides by 3.


Converting fraction to mixed number by dividing and writing the quotient as whole number and the remainder as numerator.
∴
