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.
Answer: It is True.
Step-by-step explanation:
13 + 15 = 28
3 + 5 = 8
1 + 1 = 2
Half of 28 is 14.
28 / 2 = 14
14 * 2 = 28
Hope this helps you!
The two numbers are 6 and 3
The answer is tens because all the numbers the decimal end with an ‘s’, and all the numbers the decimal end with a ‘ths’.
In this problem you will need to use the Pythagorean theorem (c^2=a^2+b^2).
The a and b represents the two edges, while c is the diagonal side and it is called the hypotenuse. Since you already know what the hypotenuse is and what one of the sides already are you just have to use the problem: c^2-a^2=b^2. Then if you plug the data you already have into the problem you will get 10^2-6^2=b^2. That then equals 100-36=b^2. Then you subtract and get b^2=64. Then you square root both sides and you get the answer b=8.
