(So “/” will basically mean divide)
450/3000=0.15
0.15*100=15% rate
Fifty , 50 20+30=50, not sure if its asking much else
Well, the answer to the question in your picture is $1200.
If x is the original price, and we took 23%, or 0.23 from that, we are left with 77%, or 0.77 of the full price.
So 0.77x = 924
x = 924/0.77
x = 1,200
1200 - 0.23(1200) = 924
924 = 0.77x
Answer:
x=11. 38 degrees; 52 degrees
Step-by-step explanation:
90+6x-14+3x+5=180
81+9x=180
9x=99
x=11
38 degrees, 52 degrees
Hello from MrBillDoesMath!
Answer: A, C, D
Discussion:
The solution of the quadratic equation ax^2 + bx + c = 0 is
x = ( -b +\- (b^2 - 4ac) ^ (1/2) ) /2a
The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution, and also occurs inside a square root (called a radicand).
The question, while intelligible, should be stated more clearly.
