Answer:
D
Step-by-step explanation:
If we look at the options and we pay attention to D,
Lets work this out Step By Step:
Part 1:
5/4(-2) = -2.5
-2.5 - 3 = -5.5 (Correct)
Part 2:
5/4(4) = 5
5 - 3 = 2 (Correct)
Both of these rows are correct.
Hope this helps!

Answer:Let's assume x be the smaller number.
Given that, The greater number is 4 more than the smaller number.
So, greater number= x+4.
It's also given that, The sum of two numbers is 52. Which means sum of x and x+4 must be equa to 52. Hence,
x + (x + 4) = 52
Step-by-step explanation:
This is most likely coming from a triangle where angle x has an opposite side of length 9.4, and an adjacent side of length 8.2, giving rise to the equation
tan(x) = 9.4/8.2
x = (tan^-1)(9.4/8.2)
Simplifying gives:
x = (tan^-1)(1.146)
x = 48.9 degrees.
This is approximately equal to 49 degrees.
