Answer:

8.75, 8 3/4 or 35/4

Step-by-step explanation:

3 1/2 + 5 1/4

=(3+5) + (1/2 + 1/4)

=8 + (2/4 + 1/4)

=8 + 3/4= 8 3/4

Answer:

8 3/4 below sea level

Step-by-step explanation:

Given that:

Depth of fish at 7:00 A. M = 3 1/2 feets below sea level

Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M

Rational number to represent position of fish with respect to the water surface at 11:00 a. M

Position at 11:00 a. M :

Addition of the two depth distances given :

(3 1/2 + 5 1/4)

7/2 + 21/4 = (14 + 21) / 4 = 35 / 4

35/4 = 8 3/4 feets below sea level

If F(x) = 3x + 10x and g(x) = 5x - 3, find (f+g)(x)
Ugo [173]
(f+g)(x) represents the sum of the two functions f(x) and g(x).

Arrange these functions vertically and add up like terms:

<span>   f(x) = 3x + 10
</span><span>+g(x) = 5x - 3
-----------------------
(f+g)(x) = 8x + 7

Please note:  You've typed in "</span><span>F(x) = 3x + 10x and g(x) = 5x - 3."
I doubt that F(x) actually equals 3x + 10x.  Please ensure that you have copied down the original problem correctly.  Come back once you've done that, so that we can finish this problem solution.</span>

Marizza181 [45]

Answer:

-71 + 22n is the equivalent expression.

This is the simplified expression.

Step-by-step explanation:

4(-11 + 4n) -3(-2n + 9)

= -44 + 16n + 6n - 27

= -44 + 22n - 27

= -71 + 22n
