Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
Let's first establish the two equations we will be using to solve the problem.
Let number no. 1 = x
Let number no. 2 = y
Equation No. 1 -
x = y + 3
Equation No. 2 -
x + y = 27
To begin with, we will substitute the value of ( x ) from the first equation into the second equation to solve for ( y ).
Equation No. 2 -
x + y = 27
( y + 3 ) + y = 27
y + y = 27 - 3
2y = 24
y = 24 / 2
y = 12
Next we will substitute the value of ( y ) from the first equation into the first equation to solve for ( x ).
x = y + 3
x = ( 12 ) + 3
x = 15
FINAL ANSWER:
Therefore, the two numbers are 15 and 12.

Answer:
<h2>D) (12 × 8) + (12 × 5)</h2>
Step-by-step explanation:
The distributive property: <em>a(b + c) = ab + ac</em>
<em></em>
We have 12(8 + 5).
Use the distributive property:
12(8 + 5) = (12)(8) + (12)(5) = (12 × 8) + (12 × 5)
To find perimeter you add up all the sides so 5cm+6cm+17cm+8cm. This will get you 36cm.
Pretty sure it’s going to be D.
Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
Step-by-step explanation:
We are given a function and we need to find domain and range of this function
Domain:
The domain of a function is the set of points for which the function is real and defined.
Since all the values give the result which is real and defined so domain is all real numbers.
Range:
The set of values of the variable that is dependent, the function should be defined.
So, all the values should be greater than 0 i.e {y | y > 0}
So, Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
