Answer:
i) or
- union, U
- addition, +
ii) and
- intersection, (upside down U)
- multiplication, x
4x/16 - 3/8 - x/16 = 3/16
x/4 - 3/8 - x/16 = 3/16
3x/16 - 3/8 = 3/16
Add 3/8 on both sides
3x/16 = 9/16
Then multiply 16 on both sides
3x = 144/16
3x = 9
Divide 3 on both sides
x = 3
13: is b because 200/10 is 10
14: 74 x 6 = 444 so the answer is C
15: 18 x 6 = 108 so D
16: 17 x 6 = 102 apartments
Yes. Here's an example : I used 4 gallons of gas and drove 28 miles. The ratio is 4gallons for every 28 miles. 4 gallons: 28 miles.
Answer:
company A since for 20 miles drive the rental is minus 20$ and in company B its more than 20. Evidently the same thing happens with 60 miles drive when in company A you have to pay 30$ and in company B 37$ Which is more expensive.
