Answer:
24
Step-by-step explanation:
all odd numbers possible: 1, 3, 5, 7
__ __ __ __
there are 4 possibilities for the first blank
for the second blank there are 4-1 = 3 possibilities as one of the numbers will have been used
for the third blank there are 4-2 = 2 possibilities as 2 of the numbers have been used
for the last blank there is only 1 possibility
so the number of solutions possible is 4 x 3 x 2 x 1 = 24
That is what you would do. How ever you could also distribute the 7 to both the 10 and the 5 and then add the two numbers together. Either way you should get the same number.
Take the neg recip of the slope -5; the correct result is 1/5.
Using the slope-intercept form of the eqn of a str line:
y = mx + b becomes 3 = (1/5)(0) + b. Thus, b = 3, and y = (1/5)x + 3 (ans)

Giiven Z is proportional to x let us suppose Z contain x as Cx where c is some constant
Z is inversely proportional to y let us suppose Z contain y as k(1/y) where k is also some another constant .
WE can write Z= (c x)/( ky )
Or Z= ( c/k) ( x/y ) where c/k is a constant
Given at x= 12 y= 4 z= 57 . let us place these values in this equation
57 = ( c/k)( 12/4)
57= ( c/k) (3)
19 = c/k we got the constant value .
we can write Z= 19( x/y)
Now if x= 18 and y = 10 we need to find Z
Z= 19( 18/10)
Z=34.2
Answer : 34.2
