Answer:
A=1665
Step-by-step explanation:
An area of a rectangle is length times width or l*w=a
I think this should be the answer!!
Both 8,15,17 and 15,20,25 will form a right triangle
If you need help with these types of problems just go into google and search Pythagorean theory silver and plug in 2/3 side lengths and if the outcome equals the third number, then that means that the side lengths make a right triangle
Answer:
$25.03725
Step-by-step explanation:
<u>Step 1: Multiply both sides by %5 to get the raise</u>
26.355 * %5 is same as 26.355 * 0.05
$1.31775 is the raise
<u>Step 2: Subtract the raise from the new salary</u>
26.355 - 1.31775
25.03725
Answer: $25.03725
Answer:
1) Subtracting one from the other
2) x = 0.375 and y = 0.125
Step-by-step explanation:
Equation 1 :
![\frac{2x+1}{2y}=7\\\\](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B1%7D%7B2y%7D%3D7%5C%5C%5C%5C)
Equation 2:
![\frac{6x-1}{2y}=5](https://tex.z-dn.net/?f=%5Cfrac%7B6x-1%7D%7B2y%7D%3D5)
To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,
![\frac{2x+1}{2y} =7\\\\2x+1=14y\\\\Multiplying\ Equation\ 1\ with\ 6\\\\12x+6=84y](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B1%7D%7B2y%7D%20%3D7%5C%5C%5C%5C2x%2B1%3D14y%5C%5C%5C%5CMultiplying%5C%20Equation%5C%201%5C%20%20with%5C%206%5C%5C%5C%5C12x%2B6%3D84y)
Now for the second equation:
![\frac{6x-1}{2y}=5\\\\6x-1=10y\\\\Multiplying\ equation\ 2\ with\ 2 \\\\12x-2=20y](https://tex.z-dn.net/?f=%5Cfrac%7B6x-1%7D%7B2y%7D%3D5%5C%5C%5C%5C6x-1%3D10y%5C%5C%5C%5CMultiplying%5C%20equation%5C%202%5C%20with%5C%202%20%5C%5C%5C%5C12x-2%3D20y)
Now subtracting equation 2 from equation 1
![12x+6=84y\\\\12x-2=20y\\\\Subtracting\ leads\ to\\12x-12x+6-(-2)=84y-20y\\0+8=64y\\8=64y\\8/64=y\\0.125=y](https://tex.z-dn.net/?f=12x%2B6%3D84y%5C%5C%5C%5C12x-2%3D20y%5C%5C%5C%5CSubtracting%5C%20leads%5C%20to%5C%5C12x-12x%2B6-%28-2%29%3D84y-20y%5C%5C0%2B8%3D64y%5C%5C8%3D64y%5C%5C8%2F64%3Dy%5C%5C0.125%3Dy)
now insert this value of y into any equation
lets insert it into equation 1
![\frac{2x+1}{2y} =7\\\\2x+1=14y\\2x+1=14(0.125)\\2x+1=1.75\\2x=1.75-1\\2x=0.75\\x=0.75/2\\x-0.375](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B1%7D%7B2y%7D%20%3D7%5C%5C%5C%5C2x%2B1%3D14y%5C%5C2x%2B1%3D14%280.125%29%5C%5C2x%2B1%3D1.75%5C%5C2x%3D1.75-1%5C%5C2x%3D0.75%5C%5Cx%3D0.75%2F2%5C%5Cx-0.375)
