To determine the expression that is equivalent to 8a + 20, all you have to do is find the common denominator and divide the values by it.
8a + 20
8a/4 + 20/4
4(2a + 5).
The correct solution would cue the second option - 4(2a + 5).
I combined the three steps together and the following are my thoughts:
We can set the fixed fee for renting as (f) and an dynamic fee related to days as (d) per day, then we have:
Then we could get f=16, d=4, so we could have the equation as follows:
y = 16 + 4x
4.003 4.03 4.033 4.3 4.303 4.33
<em><u>Question</u></em>:
Given right triangle CAT such that mC = 16.7 and a = 49, which of the following statements are true? Round to the nearest hundredth. Check all that apply.
A. angle T = 73.3°
B. t = 34.92
C. c= 14.08
D. t = 46.93
<em><u>Answer:</u></em>
The true statements are
A. angle T = 73.3°
C. c = 14.08
<em><u>Step-by-step explanation:</u></em>
Given:
a = 49
Solution:
In a triangle the sum of all its angles is 180 degrees
so in the triangle CAT
Also we can find the length of c by
c= 14.08
