48 adult tickets and 24 children tickets were sold.
Step-by-step explanation:
Given,
Cost of one adult ticket = $8
Cost of one child ticket = $3
Total worth of sold tickets = $456
Let,
Number of adult tickets sold = x
Number of child ticket sold = y
According to given statement;
8x+3y=456 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 19
Putting y=24 in Eqn 2
48 adult tickets and 24 children tickets were sold.

Answer:
1) Put a circle on the 1 and make an arrow all the way down to the left of the 1. Then put a circle on the 8 and make an arrow all the way down to the 10.
2) Put a colored in circle on the 6 and make an arrow to right all the way down to the 10. Then put a circle(thats not colored in) on the 4 and make an arrow to the right all the way down to the -10.
3) Put a colored circle on the -6 and 4

Solving real-world problems that involve inequalities is very much like solving problems that involve equations.
Example 1
In order to get a bonus this month, Leon must sell at least 120 newspaper subscriptions. He sold 85 subscriptions in the first three weeks of the month. How many subscriptions must Leon sell in the last week of the month?
Solution
Let x = the number of subscriptions Leon sells in the last week of the month. The total number of subscriptions for the month must be greater than 120, so we write :
85 + x ≥ 120.
We solve the inequality by subtracting 85 from both sides: x ≥ 35.
Leon must sell 35 or more subscriptions in the last week to get his bonus.
Check
To check the answer, we see that 85 + 35 = 120. If he sells 35 or more subscriptions, the total number of subscriptions he sells that month will be 120 or more. The answer checks out.
Example 2
Virenas Scout troop is trying to raise at least $650 this spring. How many boxes of cookies must they sell at $4.50 per box in order to reach their goal?
Solution
Let x = number of boxes sold. Then the inequality describing this problem is 4.50 ≥ 650.
We solve the inequality by dividing both sides by 4.50: x ≥ 144.44.
We round up the answer to 145 since only whole boxes can be sold.
Virenas troop must sell at least 145 boxes.
Check
If we multiply 145 by $4.50 we obtain $652.50, so if Virenas troop sells more than 145 boxes they will raise more than $650. But if they sell 144 boxes, they will only raise $648,
which is not enough. So they must indeed sell at least 145 boxes. The answer checks out.
Lyndal invested $3000 and Morton invested $2000
Answer:
Step-by-step explanation:
Standard form is Ax + By = C, so we want x to be on the left side
To accomplish this, subtract 1/4x from both sides.
Multiply by -4 to get x to be equal to 1.
