The number of birds is an illustration of ratio and proportions, and Emma is 5 years old
<h3>How to determine Emma's age?</h3>
From the complete question, Emma's age is the sum of the simplified ratio between the number of birds.
The ratio can be represented as:
Birds = 200 : 300
Simplify the ratio
Birds = 2 : 3
Add the numbers in the above ratio
Emma = 2 + 3
Emma = 5

Answer:
Step-by-step explanation:
y = -12x - 1
y = 14x - 4
-12x - 1 = 14x - 4
-1 + 4 = 14x + 12x
3 = 26x
3/26 = x
y = 14x - 4
y = 14(3/26) - 4
y = 42/26 - 4
y = 42/26 - 104/26
y = - 62/26 reduces to - 31/13
solution : x = 3/26 and y = -31/13 or (3/26,-31/13)
No. You can only add variables that have the same exponents. Also, during addition of variables with the exponent, you do not add the exponents.
