I think in this situation the best method would be a guess and check. You know that there are 8 dimes more than there are nickels. So just keep increasing each number by one until you reach $1.40. If there were 9 dimes and 1 nickels it would add up to $0.95. If there were 10 dimes and 2 nickels, it would add up to $1.10. If there were 11 dimes and 3 nickels, it would add up to $1.25. If there were 12 dimes and 4 nickels, it would add up to $1.40. So your answer is 12 dimes and 4 nickels.
I hope this helped!
We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12
The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.
To find the area of a circle, the equation we use is 3.14*r^2.
We know 17^2 is 289.
So to find the area, we simply multiply 289 by 3.14, which would be 907.46
The answer is option B.
Answer:
18
Step-by-step explanation:
because u count 2 on each side of the cube
Answer:
The answer to your question is CB = 55
Step-by-step explanation:
AC = 7x + 11
AB = 2x + 29
CB = 4x + 3 = ?
We know that AB = BC, then
2x + 29 = 4x + 3
2x - 4x = 3 - 29
- 2x = - 26
x = -26 / -2
x = 13
Find the value of CB
CB = 4x + 3 = 4(13) + 3 = 52 + 3 = 55
AB = 2x + 29 = 2(13) + 29 = 26 + 29 = 55
