We add this to the base salary and equate to the former monthy salary
We have this as;
Answer:
21 students pass
Step-by-step explanation:
Firstly, you can set up the problem into an equation where the variable X would equal the number of students passing. You put X over the total number of students in the class, turning it into a fraction, then set it equal to the fraction
(which is 75% represented as a fraction).

The fraction
can be simplified, because 75 and 100 are both multiples of 25, so after canceling out the 25s you would be left with
.

Next, you use the process of cross multiplication which is essentially just multiplying the denominators of both fractions (which would be 28 and 4 in this case) to each side of the equation.

The denominators cancel out leaving you with a simple equation to simplify.


Finally, divide both sides by four in order to isolate the variable.

X = 21.
X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
Answer:
D is the answer.
Step-by-step explanation:
Lines of symmetry is when all points touch each other so, #1 Is 5 Lines #2 Is No Because it has no lines that touch. #3 Is 4 Because its a rectangle and rectangles have 4 points so that would be 4 cause 4 points equals 4 lines. #4 Is No because Triangles have no lines.
