Answer: There are 80 nickels, 120 dimes, and 300 quarters.
Step-by-step explanation:
Since for every 2 dimes there are 5 quarters, and for every 2 nickels there are 3 dimes, there can be 4 nickels, so there will be 6 dimes and 15 quarters. When you add all of them up it equals 25, so you take 500 divided by 25, and that equals 20, so you take the 4 nickels, 6 dimes, and 15 quarters times 20.
20 x 4 = 80
20 x 6 = 120
20 x 15 = 300
Hope this helps! :D
Answer:
See below
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals. When the slopes are multiplied like 3 and -1/3 is -1.
This means the line y = -6x + 7 which has slope -6 will have a perpendicular line that has slope 1/6.
Any equation which has slope 1/6 is a solution.
Example 1/6x - 1 or 1/6x + 7 or etc.
Answer:
The correct option is B.
Step-by-step explanation:
Solution:
The shortest on map is 7cm
The longest on map is 14 cm
The shortest in real life is 120 km
Let the longest in real life is x km
So,
The ratio is:
7/120 = 14/x
x = 120*(14) / 7
x=1,680/7
x= 240 km
The longest in real-life is 240 km
Thus the correct option is B....
Answer:
12x + 40y
Step-by-step explanation:
4(3x+10y)
multiply the outer number (4) with all the terms inside the parentheses
4 X 3x + 4 X 10y
12x + 40y
