Step-by-step explanation:
The slope of (-6,5) and (7,-3) is -8/13.
Answer:
A1) 125
A2) 47.5%
B) 30
Step-by-step explanation:
Remember 'of' in this sentence means times(*). % shows a certain number/100.
a1) 48% 'of' what number is 60?
(let unknown number be x)
48/100 *x=60
Solve the equation, and the answer is x=125
a2) what percentage 'of' 120 is 57?
(let the unknown percentage be x)
(x/100)*120=57
x=47.5%
b) 24 students= 80% of the total number of students
1%=24/80
100% of the total number of students=30
So, there are total of 30 students
Answer: break the number in half. 250 is the answer
Answer:
<h2>x = 36°</h2>
Step-by-step explanation:
Since the angles lie on a straight line , it means that they are supplementary to each other. That is the sum of their angles add up to 180°
To find x add up all the angles and equate them to 180
We have
3x + 2x = 180
5x = 180
Divide both sides by 5
We have the final answer as
<h3>x = 36°</h3>
