What must be subtracted from each term of the ratio 3:7 so that the ratio becomes 2:5?
My attempt: Let two numbers be 3x and 7x. So, 3x−y7x−y=25⟹15x−5y=14x−2y⟹y=x3. But the answer is given as 13 only.
I wish somebody could provide some clarifications.
Answer:
The acceleration is 965 kg•ms^-2
Step-by-step explanation:
Mathematically;
Force = mass * acceleration
From the question;
Force = 1930 N (kg• ms^-2)
mass = 2kg
Acceleration = Force/mass = 1930/2 = 965 ms^-2
Have you learned about the Pythagorean theorem? a² + b² = c² . . . you should teach them about this.
For question number 1, the correct answer would be the x coordinate would be the same, or will not change.
For question number 2, the correct answer would be (-4,-7)
For question number 3, the correct answer would be <span>A'(5, -3), B'(2, -1), C'(-2, -4)
For question number 4, the correct answer would be </span><span>R'(-3, 2), S'(-5, -2), T'(-6, 0)
If you have any questions, just ask. ;)</span>
