We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!
Answer:
Step-by-step explanation:
If we want to share £5 to the ratio of 1/3 we should follow this steps :
- our ratio is 1/3 so we should add 1 and 3 together to find the total number of parts : 1+3=4
- divide the total amount by the number of parts : 5/4 = 1.25
- multiply each number in the ratio by 1.25 : 1.25*1=1.25 and 1.25*3=3.75
the answer is 1.25 and 3.75
It was obvious from the beginning that the answer would be the last one since ut had two numbers
- following the same steps you get again in the second question :

Answer:
Sarita is wrong, the correct equation is ![y=-3x+7](https://tex.z-dn.net/?f=y%3D-3x%2B7)
Step-by-step explanation:
we know that
The equation of a line in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
we have
![point(3,-2)\\b=7](https://tex.z-dn.net/?f=point%283%2C-2%29%5C%5Cb%3D7)
substitute in the equation
![-2=m(3)+7](https://tex.z-dn.net/?f=-2%3Dm%283%29%2B7)
Solve for m
![3m=-2-7](https://tex.z-dn.net/?f=3m%3D-2-7)
![3m=-9](https://tex.z-dn.net/?f=3m%3D-9)
![m=-3](https://tex.z-dn.net/?f=m%3D-3)
substitute
![y=-3x+7](https://tex.z-dn.net/?f=y%3D-3x%2B7)
therefore
Sarita is wrong
I'm pretty sure the original price would be $90.75 because 3/4 is .75, so all you have to do is add that to the $90
