The answer is 640 because if you multiply the total student of 6h grade by 100 and divide by 30. You will get the total of student in the school
m<JKL=45°
Please see the attached picture for full solution
hope it helps..
Good luck on your assignment...
Answer:
y = 3
Step-by-step explanation:
2y - 3 =
square both sides to remove sqrt bracket
(2y - 3)^2 = ( )^2
simplify both sides
(2y - 3)(2y - 3) = - 10y + 12
- 12y + 9 = - 10y + 12
bring all value to left side
- 2y - 3 = 0
factor
(y - 3)(y + 1)
solve for y
y = 3, y = -1
When plugged back into the equation, only y = 3 is true
1/3x - 2 = 1/4x + 11....it looks to me like one y was subbed in for another...
ur 2 equations are :
y = 1/3x - 2 and y = 1/4x + 11...but we need them in standard form...
y = 1/3x - 2
-1/3x + y = -2 ..multiply by 3
-x + 3y = -6.....or 3y - x = -6 <==
y = 1/4x + 11
-1/4x + y = 11 ...multiply by 4
-x + 4y = 44 or 4y - x = 44 <==
