Step 1: Understanding the Given Equations
We have three equations:
- A + A = 30
- B + B = 20
- C + C = 8
And we need to solve:
A + B × C = ?
Step 2: Finding the Values of A, B, and C
Solve for A:
- The equation is A + A = 30.
- This means we are adding A to itself, so we can rewrite it as:
2A = 30. - To find A, divide both sides by 2:
A = 30 ÷ 2 = 15.
Solve for B:
- The equation is B + B = 20.
- Rewriting it:
2B = 20. - Divide by 2:
B = 20 ÷ 2 = 10.
Solve for C:
- The equation is C + C = 8.
- Rewriting it:
2C = 8. - Divide by 2:
C = 8 ÷ 2 = 4.
Step 3: Solve A + B × C
Now, we substitute the values we found:
A + B × C
= 15 + 10 × 4
Step 4: Apply BODMAS/BIDMAS Rule
(BODMAS stands for Brackets, Orders, Division/Multiplication, Addition/Subtraction)
- First, do the multiplication:
10 × 4 = 40 - Now, add 15 + 40:
= 55.
Final Answer:
55 ✅
