(i) Note that it is given to you that 3a + 2b = 9
You are trying to find the value of 9a + 6b. Find what is multiplied to both the variable a & b. Divide:
(9a + 6b)/(3a + 2b) = 3
Next, multiply 3 to the 9 on the other side of the equation:
3 x 9 = 27
27 is the value of 9a + 6b.
(ii) Note that it is given to you that 8x + 6y = 60
You are trying to find the value of 4x + 3y. Find what is multiplied to both the variable x & y. Divide:
(8x + 6y)/(4x + 3y) = 2
Next, divide 2 from the 60 on the other side of the equation:
60/2 = 30
30 is the value of 4x + 3y.

Answer:
The correct answer is C on edgen 2021
Step-by-step explanation:
I legit just took a lucky guess and got it right lol
The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
For simplicity’s sake:
D = dogs, C = cats, R = rabbits
Since the dogs and the cats are the same number, we can say C = D.
R = 1/4D
2D + 1/4D = 36
Combine like terms and get the same denominator
9/4D = 36
9D = 144
D = 16
Now we know that D is 16, so C must be 16 as well. That leaves us with 32 cages.
36 - 32 = 4 rabbit cages. To double check this, 1/4 of 16 does equal 4.
Final answer: 16 D, 16 C, 4 R
