Answer:
x = 76 roses
Step-by-step explanation:
Step 1: Define variables
x = # of roses
y = # of tulips
Step 2: Write systems of equations
x = 4y + 8
5x + 2y = 414
Step 3: Use Substitution
5(4y + 8) + 2y = 414
20y + 40 + 2y = 414
22y = 374
y = 17
Step 4: Plug in <em>y</em> to find <em>x</em>
x = 4(17) + 8
x = 68 + 8
x = 76

Answer:
Father's age = 64 years
Step-by-step explanation:
Given:
Mummy's age = Aliyah's age + 32
Father's age = Mummy's age + 8
Tota age = 144
Find:
Father's age
Computation:
Assume;
Aliyah's age = a
So,
Mummy's age = a + 32
Father's age = a + 32 + 8
Father's age = a + 40
Aliyah's age + Mummy's age + Father's age = Total age
a + a + 32 + a + 40 = 144
3a + 72 = 144
3a = 144 - 72
3a = 72
a = 24
Father's age = a + 40
Father's age = 24 + 40
Father's age = 64 years
