Answer:
3a, 13cm 5, 1:200
Step-by-step explanation:
In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm
then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200
I had difficulties with these as well. If you need extra help with the task 3 please pm me :)

Answer:
4
Step-by-step explanation:
Since it costs $3.75 for every earring, multiply e by 3.75 like this: 3.75e
Add 9.5 on top of that since Dani already bought the necklace for $9.50
3.75e + 9.5
This sum has to be less than or equal to 25 because the budget is $25
3.75e + 9.5 ≤ 25
To find e subtract 9.5 from both sides
3.75e + 9.5 ≤ 25
- 9.5 - 9.5
3.75e ≤ 15.5
Divide both sides by 3.75
3.75e/3.75 = 15.5/3.75 = 4.133...
You can't buy 0.133 of an earring, so the max amount of earrings she can buy is 4.
The copy is the exact same as the original, so the scale factor would be 1.
The answer is the first choice
