Answer:
<u>2 : 4 : 1</u>
Step-by-step explanation:
First take common factors by factorization.
56 = 14 x 4 = 28 x 2
112 = 14 x 8 = 28 x 4
28 = 14 x 2 = 28 x 1
Remove the 28 common factor.
Therefore,
56 : 112 : 28
= <u>2 : 4 : 1</u>
Answer:
3x^2 + xy - 10y^2
Step-by-step explanation:
1. Use the FOIL method
3x
^2 − 5xy + 6yx − 10y
^2
2. Collect like terms
3x
^2
+ (−5xy + 6xy) − 10y^2
3. Simplify
3x
^2
+ xy − 10y^2
In 4 hours if you count the miles by the road linking the 2 buses. This is because 55 for one bus and 45 for the other bus added together equals 100 miles/hour. Therefore, 4 hours will be the time the 2 buses are 400 miles apart.
Answer:
c)
Step-by-step explanation:
16) Cost price = Selling price * 100 / (100- loss%)
= 800 * 100 / 80 = 10*100 = 1000
Loss = Cost Price - Selling price = 1000 -800 = 200
