12.8-12.4=0.4
0.4 divide by 12.4 = 0.0322
0.0322 x 100 = 3.22%
we are given with the inequality
Open the parenthesis we get on left side we get
7
The answer is 7
The ratio would look like 35/7
Let the missing number be x
r= x/50= 450/x
x^2 = 22500
x = 150
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
