Number of students who secured first class in English only is 20
Step-by-step explanation:
- Step 1: Find the number of students who secured first class in English only.
Total number of students who secured first class in English or Maths, T = 80
Number of students who secured first class in Maths, M = 50
Number of students who secured first class in both English and Maths, EM = 10
⇒ Let the number of students who secured first class in English only be x.
Total students with first class, T = M + EM + x
⇒ 80 = 50 + 10 + x
⇒ 80 = 60 + x
∴ x = 80 - 60 = 20

Can u help me with a question I’m in 5th grade
To find the y intercept you use this equation:
y2 - y1
Same for x intercept:
x2 - x1
Pick two points, put in the values, and solve.
(-5,-7) and (0,-5)
-5 - (-7) = 2
0 - (-5) = 5
The y intercept is (0,2)
The x intercept is (5,0)
Hope this helps! :)
