I got 7.5 because 3•5=15 and then you can divid 15 by 2 since it is a triangle
There are 7 bricks in the first row of the structure
The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes
Step-by-step explanation:
Given,
Monthly rate = $1295
Per minute charges = $25
Bill for x minutes = $212000
As x are the total minutes.
Per minute charges * Total minutes + Monthly rate = Bill for x minutes
25x+1295=212000
Dividing both sides by 25
The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes

Answer:
220
Step-by-step explanation:
Let us assume that x number of necklaces are to be fixed to break even i.e. cost price = profit.
Now, cost for x necklaces is 35x + 1650, and selling price is 85x. {As per given condition}
Therefore, profit will be = 85x - (35x +1650) =50x -1650
Hence, to make break even, the condition is
50x - 1650 = 35x + 1650
⇒15 x =3300
⇒ x =220.
Hence, 220 number of necklaces must the jeweler fix to break even. (Answer)
