Answer:
12:4, 12 to 4, 12/4
Step-by-step explanation:
tiger exhibit : gorilla exhibit
tiger exihbit = 12 students
gorilla exhibit = 4 students
Angles that are complementary end up equally 90 degrees. That means 30 degrees is one and 60 is the other because 30*2 = 60
60+30=90
<u>ANSWER</u>
<u>EXPLANATION</u>
This very simple to do.
First locate the entry in 
in matrix A. That is the entry in the intersection of the fourth row and first column of matrix A. This entry is 
.
Then multiply by the scalar which is 2 to get,
.
Next we locate the entry in 
in matrix B also. Which is 
. We multiply by the scalar of 
to get,
.
We now add these two corresponding entries to obtain,
See diagram
1. Parenthesis:
(15)8 - 4 + 2 + 1
Multiply:
120 - 4 + 2 + 1
Subtract:
116 + 2 + 1
Add:
119, the answer is A.
2. 8 x 15 = 120
120 / 2 = 60
6 x 15 = 90
90 + 60 = 150
The answer is A.
Hope this helps!
Hey there! :)
If you switch the equation around, it becomes: 14 + x = 4
x = -10 because: -10 + 14 = 4
x = -10
Hope this helps :)
