Question

Create and solve a linear equation that represents the model, where circles and a square are shown evenly balanced on a balance beam.

1) x + 6 = 16; x = 10
2) x + 10 = 6; x = -4
3) x = 6 + 10; x = 16
4) x + 6 = 10; x = 4

Answer 1

x + 6 = 10; x = 4

Explanation:

i did the test

Answer 2

For this case, the first thing you should do is define variables:
x = number of balls that contains the square.
On the one hand, we have:
left side: square + 6 balls
On the other hand:
right side: 10 balls
We then have to balance:
x + 6 = 10
Clearing x we have:
x = 10-6
x = 4
Answer:
a linear equation that represents the model is:
4) x + 6 = 10; x = 4
