The common base that can be used to rewrite each side of the equation is 2.
<h3>How to find the common base used to rewrite each equation?</h3>
The common base that can be used to rewrite each side of the equation is as follows:
2ˣ⁺³ - 3 = 5
add 3 to both sides
2ˣ⁺³ - 3 + 3 = 5 + 3
2ˣ⁺³ = 8
Hence,
2ˣ⁺³ = 2³
Therefore, the common base that can be used to rewrite each side of the equation is 2.

Area of rectangle = 1035 cm^2
length of rectangle = 3 cm
width of rectangle = ?
area = length *width
1035 = 3*w
w = 1035/3
w = 345
Answer:
Expected counts: 55 ducks, 25 geese, 13 cranes, 11 swans, 6 heron
Observed counts:
61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons.
Step-by-step explanation:
There are 61+17+11+15+6 = 110 birds on the lake.
The expected counts are:
0.50*110 = 55 ducks
0.23*110 = 25 geese
0.12*110 = 13 cranes
0.10*110 = 11 swans
0.05*110 = 6 herons
What the biologist counted were the observed counts.
$20 is 10% is what he earned, and 10 is a factor of 100 (100 for 100%).
Since 10 x 10 is 100, we will also have to multiply 20 by 10: 200
Answer: $200 is what Barak earned by working in the pizza parlour.
