All of the numbers add to 52... then you divide them all b 52 and round them to the nearest thousands. ANSWER: 15/52= 0.288 9/52=0.173 22/52= 0.423 6/52= 0.115
First of all, expand the left hand side:
Sum like terms:
Add 3 to both sides:
Subtract 3x from both sides:
So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.
Answer:
D
Step-by-step explanation:
There were 144 students when the contest began
<h3>What is Equation
?</h3>
Equation is formed when an algebraic expression is equated by a constant or another algebraic expression.
On the basis of given data :
Let the total number of students are x
50% of the students are eliminated after the first round
the remaining students are 0.5x
After the second round = (1/3) * 0.5 x were remaining
and
(1/3) * 0.5 x = 24
then solving this equation will give the total number of students
0.5x = 24 * 3
x = 24*3 /0.5 = 144
Therefore there were 144 students when the contest began
