Answer:
We know that 30/25 is 1.2 or 1 1/5. SO if we divide 20 by that then we'll get 16.6667. So I won't give you the answer because its best that you learn to do this yourself because its more beneficial than telling you. What you have left is 16.6667=4x-4. Combine like terms and you'll get your answer. But if your still stuck then you can just let me know and I'll help you as much as I can.
Answer:
12 cm
Step-by-step explanation:
width = x
length = x + 5
perimeter = 38cm
perimeter = length + width + length + width
x + 5 + x + x + 5 + x = 38
4x + 10 = 38
4x = 28
x = 7
length = x + 5 = 7 + 5 = 12
If the quiz is worth 50 points and each question is worth 10 that means for every question he could’ve missed would be taking away 10 from that 50. So lets say if he misses 2 questions. 2 x 10 would be 20. You take away 20 from 50 which would be: 50 - 20 = 30. And it goes on from there.
Hope that helps!
