<h2>
After full 30 days John will have 15 dozen speckled eggs to sell.</h2>
Step-by-step explanation:
Total number of hens John has = 51 hens
If there are 3 more hens, then total number of hens = 51 + 3 = 54 hens
Now, one third of the hens are speckled.
⇒ 18 hens are speckled.
Now, of the total 18 speckled hens lay speckled eggs.
⇒ 9 hens produce speckled eggs.
Now, one hen lays one egg in a day and a half.
⇒ 9 hens lay nine eggs in a day and a half
.
⇒ 9 hens lay 180 (15 doz.) eggs in days
Hence, after full 30 days John will have 15 dozen speckled eggs to sell.
The difference is tha in algebraic expression, there are variables (ex. 6x + 3x) unlike numerical expression doesn't contain a variable; its just numbers.
You would have to use the matrices option on the calculator, clearly defining your variables. (Also arrange them so that the variables are in the same exact spot in equation equations; i.e. variables on the left side in a certain order and the answer on the right side)
Begin by clicking 2nd--> matrix (its in x⁻¹)--> edit --> [A] --> specify the size to be 3×4
Write out just the coefficient of each variable, all under a single column (for the specific variable).
The answer (or the number on the right side of the equation) would be the last box on the right.
Return back to the home screen with 2nd--> quit (under mode)
Click 2nd--> Matrix--> math --> B: rref( --> 2nd --> matrix--> names--> [A] --> enter.
Click enter to see the solution.
Hope I helped :)
something is wrong on your question
ie 6x^ is there a missing number
The circumference or perimeter of the circle has the formula 2*pi*r, where r is the radius of the circle. This could then be easily calculated:
C = 2*pi*r
53.38 = 2*3.14*r
53.38 = 6.28r
r = 53.38/6.28
r = 8.5 ft
Thus, the radius of the circle has a length of 8.5 feet.
