Answer:
The number is -3.
Step-by-step explanation:
Set up an equation:
Variable n = number
12 + 7n = n - 6
Assuming the question is solve for n, isolate the variable:
Subtract n from both sides:
12 + 6n = -6
Subtract 12 from both sides:
6n = -18
Divide by 6 on both sides:
n = -3
Check your work:
12 + 7(-3) = -3 - 6
12 - 21 = -3 - 6
-9 = -9
Correct
Step-by-step explanation:
Using log properties

Plug in the knowns
Answer: 114
Step-by-step explanation:
To find the perimeter, you will find the distance around the shape by adding the numbers.
The is one missing side and to find that side you will subtract 10 from 38.
38 - 10 = 28
Now add the them.
28 + 5 + 10 + 26 + 10 + 35 = 114
Answer:
x=4
Step-by-step explanation:
ABCD is a rectangle, so AD and BC are parallel. Thus, The angle complementary to 6x+19 is 47.
6x+19+47=90
6x+66=90
6x=24
x=4
