Answer:
x=25, 120
Step-by-step explanation:
The two angles form a straight line so they add to 180
60 + 4x +20 =180
Combine like terms
4x+80 = 180
Subtract 80 from each side
4x+80-80 =180-80
4x= 100
Divide by 4
4x/4 =100/4
x= 25
The exterior angle is
4x+20 = 4*25+20 =100+20 =120
Answers:
(2) Option (B) 4
(3) The answer is: +1
Explanations:
(2) The plus sign in the limit indicates that it is the right hand limit. So we have to approach to 2 from the right side of the graph. When we do that, we see the value of y = +4. Hence the correct option is (B) 4
NOTE: Although the question seems complex because there is slope involved but in this particular case, the examiner is concerned about the right hand limit.
(3) The minus sign in the limit indicates that it is the left hand limit. So we have to approach to 3 from the left side of the graph. When we do that, we see the value of y = +1. Hence the correct answer is +1.
Her team scored a total of 22+39 = 61 points. This is 8 points higher than the other team, so the other team scored 61-8 = 53 points.
As for which expression your teacher wants as the final answer, it will depend on how simplified you want it to be. You could have the following possible answers:
Other expressions may be possible as well.
The equation for that statement is 58 * x - 136 = -70
