I think it’s C because he put 229.79 in his acount but then he withdrew (took out) 229.79 which leaves him with no money.
When you distribute the 6, you equation will look like this...
24x + 12 + 3x
All you need to do is combine like terms and your equation is...
27x + 12
So your answer is B :)
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.
