The answer to this question is:
9x+8/3x^2
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
Answer:
Step-by-step explanation:
I can solve 4 for you.
a - 3a
1a - 3a
= 2a
Answer:
1) x = 3
y = 42
2) x = 50
y = 70
Step-by-step explanation:
1) 12x + 6 = 14x
6 = 2x
x = 3
14(3) = y
42 = y
2) 2x + 10 + x + 20 = 180
3x + 30 =180
3x= 150
x=50
2(50)+10=110
110-180
y=70
Since it's a circle it's supposed to equal 360 so add 80 + 90= 170 subtract that from 360 that equals 190 so your answer was right. It's none of those
