Step-by-step explanation:
angle ABC= angle ACB= 37° --------- because AB=AC
angle ACB+ angle ACD=180°
37+angle ACD=180
angle ACD=143°
The area of the parallelogram is given by:
A = b * h
Where,
b: base
h: height
Substituting values we have:
A = (16.5) * (6)
A = 99 feet ^ 2
The number of packages will be:
N = 99/5
N = 19.8
Rounding:

Answer: B
Step-by-step explanation:
Let's solve the given equation. Then we can see which other equation has the same answer.
-5n+31=-14n-5
36=-9n
n=-4
We need to fina another equation that gives n=4 as the answer.
A. Incorrect
3-6n+3n=-3+4-4n
3-3n=1-4n
n=-2
B. Correct



C. Incorrect
1=0.75n+3.25
-2.25=0.75n
n=-3
D. Incorrect
-1-22n=-20n-9
8=2n
n=4
When you divide 52 by 8, you have to find the nearest multiple of 8 that is either equal to or less than 52.
closest multiple of 8 that is less than 52 is 48. Quotient is the number of times 8 is in 48. In other words 8 is there 6 times in 48.
quotient is found by dividing the closest multiple of 8 (48) by 8.
48 / 8 = 6
quotient is 6
remainder is the difference between the number given and closest multiple
number given is 52. closest multiple is 48. difference between 52 and 48 is
52 - 48 = 4
the remainder is 4
quotient is 6
