The total cost is $12.91
Step-by-step explanation: Substitute the number of pounds for each given supply. Multiply to get the individual amounts, then add all of those amounts to find the total cost.
1.29(2) + 0.79(4) + 2.39(3) = total
2.58 + 3.16 + 7.17 = 12.91

Answer:
yes
Step-by-step explanation:
The value of x will be 3
From given diagram, triangle ABC and EDC meet at a common vertex C.
So, triangle ABC and EDC both are congruent to each other.
Applying the similarity property of congruence, ratio of the congruent triangles' corresponding sides will be equal.
Therefore,


Simplifying the expression,
We get
(18-x)/x = 25/5
(18-x)/x = 5
18-x = 5x
18-x-5x = 0
18 - 6x = 0
- 6x = -18
x = 3
Hence, the value of x is 3.
