The relation between the numbers is 2:5 so it would be 2x and 5y and you plug in the numbers. When x=42 which is 2(21) then y would be 5(21) which equals 105 :-)
Answer:
12.8
Step-by-step explanation:
Here multiplication is done before addition.
Given
4.8 × 2 + 3.2 ← perform multiplication
= 9.6 + 3.2 ← perform addition
= 12.8
Answer: x = 6
1. Subtract “2x” on both sides. This simplifies the equation to x+5=11
2. Subtract “5” on both sides. This simplifies to x=6, which is your answer.
