Mathematics
1 answer:
Sloan [31]3 years ago
8 0

Step-by-step explanation:

y=kx

say that y is the original prince and x is the sale price

15=k(10)

15/10=k

3/2=k

you can check with the next problem to check if it is the same

25=k(20)

25/20=k

5/4=k

so you take 5/4-3/2=-1/4 so the constant is -1/4

Hope that helps :)

If x is an odd number,write an expression for the odd number that comes directly before x.
Aleksandr [31]
Lets just say hypothetically that x=7. So to find the odd number before 7 we need to subtract a number. The odd before 7 is 5 which is 7-2. So by subtracting 2 from a odd value you get the odd value befire it so your equation is x-2

In the figure, angle B measures 44°, angle A measures 62°, and angle E measures 50°.
Gre4nikov [31]
We don't need the figure
angle b = 44 degrees
angle a = 62 degrees
angle e = 50 degrees
angle f = unknown
we know that 
angle a + b + e + f = 180 degrees
50 + 44 + 62 + f =180 degrees
f= 180-50-44-62
but here there is only one blank so we have to add 44 and 62 to make one number that is 106
therefore, f = 180-50-106
if you further want to solve it angle f is 24
