Answer:
D. The sum is a rational expression.
Step-by-step explanation:
the given expression is a/b +c/d
so in the question it is given that b and d are non zero values
a/b is rational number and c/d is a rational number
so if both are rational number , so we know that the sum of rational number is also a rational number.
The right option is D. The sum is a rational expression
Answer:
In B) y = x/7 , the constant of proportionality is 7.
Step-by-step explanation:
Two quantities X and Y are said to be in proportion if and only if
X = kY or, 
,
where k = Proportionality Constant.
Here, 7 is the constant of proportionality. Then,
A . y = 14x
here, 
≠ 7
B . y = x/7
here, 
= constant of proportionality .
C. y = x
here, 
≠ 7
Answer:
I got 17.
Step-by-step explanation:
Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)
1 - 0.16 = 0.84
21/0.84 = 25
