5x + 8 - 3x = 10
First you can combine the like terms.
5x - 3x + 8 = 10
2x + 8 = 10
- 8 - 8
2x = 2

x=1

Determine the store with the lowest unit rate
To do this, we simply divide the price by the weights in each store
For Store 1:


For Store 2:


For Store 3:


<em>Comparing the unit rates of the three stores, we can conclude that store 2 offers the least unit rate</em>
Answer:
AO=8
Step-by-step explanation:
8, because point O is the centroid because it is the intersection point of the medians. The distance from a vertex to the centroid is always the same, and the ratio of the distance from a vertex to the centroid to the distance from the centroid to the side is always 2:1. So, we know that since FO=4, CO=8. AO=CO, so AO=8.
(8/4) = (10/x)
8x = 4 x 10
8x= 40
x = 40/8
x=5
