Answer:
perimeter=sum of all sides
=7x - 6 + 3x + 4 + x
=7x + 3x + x + 4 - 6
=11x - 2
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
the sum of the exterior angles of a polygon = 360°
sum the 4 exterior angles and equate to 360
8x + 9x + 5 + 5x + 4 + 9x + 3 = 360 , that is
31x + 12 = 360 ( subtract 12 from both sides )
31x = 148 ( divide both sides by 31 )
x ≈ 11.23 ( to 2 dec. places )
then exterior angle at B is
9x + 3 = 9(11.23) + 3 ≈ 104° → C
Answer: deduction???
-------------------------------
A = number of $1 bill
B = number of $5 bill
A + B = 1919
A*$1 + B*$5 = 5959
so
A + B = 1919
A + 5B = 5959
Substract both equation
A + 5B - (A + B) = 5959 - 1919
4B = 4040
B = 1010
And
A = 1919 - B = 1919 - 1010 = 909
A = 909
Check the result :
A*$1 + B*$5 = 909 + 1010*5 = 909 + 5050 = 5959
Answer: 60 % - percent of increase
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Original number of cups: 5
</em>
- <em>New number of cups: 8
</em>
For the first part, because the original number of cups increases, the percent of change is an increase.
To find the number:
(new number -original number ) / (original number) =
Replacing with the values given:
(8-5) /5 = 0.6 (decimal form)
To obtain the percentage we have to multiply it by 100:
0.6 x 100 =60%
In conclusion, we have a 60 percent of increase.
