It looks like the given equation is

234₅ + 434₅ + x₅ = 2304₅

First, we have

234₅ + 434₅ = 1223₅

because

• 4₅ + 4₅ = (8)₅ = (5 + 3)₅ = 10₅ + 3₅ = 13₅

(carry the 1)

• 3₅ + 3₅ + 1₅ = (7)₅ = (5 + 2)₅ = 10₅ + 2₅ = 12₅

(carry the 1)

• 2₅ + 4₅ + 1₅ = (7)₅ = (5 + 2)₅ + 10₅ + 2₅ = 12₅

Then x₅ = 2304₅ - 1223₅. We have

• 4₅ - 3₅ = 1₅

0₅ - 2₅ is negative, so we borrow a 1 from the next digits place,

• 10₅ - 2₅ = (5)₅ - 2₅ = 3₅

• (3 - 1)₅ - 2₅ = 2₅ - 2₅ = 0₅

• 2₅ - 1₅ = 1₅

x₅ = 2304₅ - 1223₅ = 1031₅

The bird population on an island is declining at a rate of 2.2% per year. If the population was 3500 in the year 2009, which is

andreyandreev [35.5K]

In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500* $(1-0.022^{5})=3500*0.978 x^{5}$ = 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.

So with the problem the equation for answering these would be “1.50t+4=c” so to plug in the variable for t would be 0, 1, 2, 3, etc. and the variable c would be the answer of solving the equation with the plugged in number
1.50(0)+4= $4.00
1.50(1)+4= $5.50
1.50(2)+4= $7.00
1.50(3)+4= $8.50
