Answer:
21%
Step-by-step explanation:
Out of the 25 + 9 + 12 + 21 + 12 + 21 = 100 total rolls, 6 came up 21 times so the percentage is 21/100 = 21%.
Answer:
tell me the question
Step-by-step explanation:
Since the question is asking for the no. of coins each, we can represent the numbers with variables.
number of quarters = x
number of dimes = 6x (because there as 6 times as many dimes as quarters)
Next we can multiply the variables by the value of each coin.
25x + 6(10)x = 1275
25x + 60x = 1275
(make sure the expressione quals 1275, not 12.75. A dime is not 10 dollars, nor is a quarter 25 dollars).
85x = 1275
x = 15
Now that we have the value for x, plug it back in.
Andrea has 15 quarters and 90 dimes.
3 feet is 36 inches.
36 x 4 is 144.
There are 144 1/4 inch pieces in 3ft of fishing line.
Answer:
solution = (1.-2)
Step-by-step explanation:
put x= 1 and y = -2 in this system : y=-4x+2 and y + 2x = 0
you have : - 2 = - 4(1)+2 and -2 +2(1)=0
-2=-2 and 0=0 .....right
