Answer:
$46
Step-by-step explanation:
Let the amount of money Darius's parents sent to the book fair be represented as:
We are told that:
Darius's parents sent money to the book fair to be split among the four children in his family. After they gave the money to the cashier, she told each child they had $11.50 to spend.
The Equation is give as:
x = 4 × $11.50
x = $46
Therefore, the total amount of money Darius's parents sent to the book fair is $46
210 * 60% = 126
126 + 210 = 336
So, $336 would be your answer.
Let the weight of triangle be x units. You are given that the weight of square is 1 unit.
1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.
2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.
3) If the whole system is balanced, then the weights on left and right sides are equal:
3x+5=2x+7.
Solve this equation:
3x-2x=7-5,
x=2 units.
Answer: option A
