Answer:
5,9,10.
Step-by-step explanation:
The factors of 20 that I know of are 2,5,10
The possible square no. is below 10 that is, either 4 or 9
Using the above no's you can substitute to see which three give 24 as the sum, thus 5,9,10

all real values of x where x < -1
Answer:
<h2>5</h2>
Step-by-step explanation:
Given the following angles ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21, the expression is true about the angles;
∠AOC = ∠BOC+∠AOB
Substituting the given values into the expression, we will have;
21 = x+3+4x-7
collect the like terms
21 = x+4x+3-7
21 = 5x-4
Add 4 to both sides
21+4 = 5x-4+4
25 = 5x
Divide both sides by 5
5x/5 = 25/5
<em>x = 5</em>
<em></em>
<em>Hence the value of x is 5</em>
Answer: 40 tickets.
Step-by-step explanation:
Let's call:
x: the number of child tickets sold that day.
y: the number of adult tickets sold that day.
Based on the information given in the problem, you can make the following system of equations:
You must use the method of substitution to solve the system of equations:
Substitute y=3x into the second equation and solve for x:
Then the answer is: 40 tickets.
