Answer:

I=5a+2 (simplified form)


Step-by-step explanation:

I is the total length of all the 5 rods.

Each of the 5 parts lengths are (a-1), a, a, a, (a+3), respectively.


<em>We add all of them and equate it to I:</em>

I=(a-1)+a+a+a+(a+3)

<em>Simplifying this, we take like terms and add:</em>

<em>I=(a-1)+a+a+a+(a+3)\\I=5a-1+3\\I=5a+2</em>

The members of a book club spend the same amount of money for refreshments at each meeting. At one meeting they bought 6 bagels
Tom [10]

The members of a book club spend $0.4 for each Bagel as refreshment.

Let x represent the cost of each bagel.

At a meeting, they bought 6 bagels and spent $9.00 on beverages, hence:

Cost = 6x + 9

At another meeting, they bought 8 bagels and spent $8.20 on beverages, hence:

Cost = 8x + 8.20

Since the same money is spent on each meeting, hence:

6x + 9 = 8x + 8.2

2x = 0.8

x = $0.4

Therefore the cost of each bagel is $0.4
