Answer:
10 motorcycles and 30 cars
Step-by-step explanation:
If there are 25 cars and a 5:2 ratio, then 25/5=5, and 5x2=10, then there will be 10 motorcycles.
5:2
Divide by 5 | Multiply by 2
If there are 12 motorcycles, then 12/2=6 and 6x5=30. The ratio is reversed because the translation required is reversed.
2:5
Divide by 2 | Multiply by 5
Answer:
Step-by-step explanation:
2(4z+3+3z)=174
7z+3=174/2=87
7z=87-3=84
z=84/7=12
WX=3z=3×12=36 units
Answer:
4.61% increase (round up as needed)
Step-by-step explanation:
Subtract the smaller amount from the larger to find the dollar difference

Then divide the difference by the original amount

Move the decimal point over two spaces (multiply by 100) to get your percentage
0.0461=4.61%
Round up as needed.
The answer is 330. 67x5=335. Now round it.
