its A because 55 - 17 = 38
17 * 2 = 34
38 - 34 = 4
hope this helps :)
We have one -4 so we leave that alone.
4x4x4x4x4x4x4 is the same as 4^6
So, we can rewrite the equation to -4 * 4^6
Best of Luck!
(x,y) =(7,2) so 7 is x and 2 is y, hope this helps
We know that a nickel equals $0.05.
We know that a dime equals $0.10.
So we will start by looking at the basic pricing of each coin, then to look into writing this problem out in an basic algebra a format. *key - anytime you are trying to find out the amount (value) that is written out in word format you always want to convert it into an equation to get your solution.*
We will use x (which is the most common) for the number of dimes that we have.
44-x (so x is the amount of dime, and 44 is the total coins that we have all together between the nickles and dimes).
0.10 (the price of a dimes)x+0.05 (the price of the nickles)*(44-x)=3.10 (the total amount of the nickels and dimes together.
Always use your rule of PEMDAS
10x+5*(44-x)=3.10
10x-5x=310-5*44
5x=90
x=18 (this is simplified)
So there are 18 dimes and then there is 26 nickels which = $1.30.
So your answer is going to be $1.30.
You can check your work by, the 18 dimes would be 44-18 which is 26 and then the value of the nickels 26*$0.05=$1.30
The length of XY on the line segment WY is 6 units.
<h3>How to find line segment?</h3>
The full line segment is WY.
Point X is on the line segment WY.
Therefore,
WY = 16 units
WX = 10 units
XY = WY - WX
Hence,
XY = 16 - 10 = 6 units.
Therefore, the length of XY on the line segment WY is 6 units.
