If the scale factor of Figure A to Figure B is 7:2, find the perimeter of Figure A.
Answer:
122.5 units
Step-by-step explanation:
The proportion would be between the perimeters and the given ratio:
7/2 = p/p
Where P is the perimeter of the bigger figure and p is the perimeter of the smaller figure.
Remember that the perimeter is the sum of all sides, using all given values and solving for P, we have
7/2=P/9+5+9+12
7/2=P/35
7(35)/2=P
P=245/2=122.5
Therefore, the perimeter of Figure A is 122.5 units.

The mixture sells for $2.00 per pound. Which system of linear equations can be used to find the amount of each ingredient in the mixture?
A) xy = 17
1.60x + 2.45y = 34
B) x + y = 17
1.60x + 2.45y = 34
C) x + y = 17
1.60x + 2.45y = 17
D) x + y = 17
1.60x − 2.45y = 34
Answer: B) x + y = 17
1.60x + 2.45y = 34
Step-by-step explanation:
Cost of x = $1.60 per pound
Cost of y = $2.45 per pound
Total pounds of x and y = 17
Cost per pound of mixture = $2
Total number of pounds of the mixture :
x + y = 17
Since the cost per pound of the mixture = 2
Hence ;
(Cost of x * number of pounds of x) + (Cost of y * number of pounds of y)
(1.60 * x) + (2.45 * y) = (cost per pound of mixture * total number of pounds of the mixture)
1.60x + 2.45y = 2 * 17
1.60x + 2.45y = 34
Answer: answer is B

20 Points!
I'm Really confused on this please help.
Write three points (x, y) that exist on the line.
Answer:
3 points on the line - (.5,3) (1,2) (1.5,1)
Step-by-step explanation:
y = -2x + 4 (1.5,1)
1 = -2x + 4 subtract 4 from each side
-3 = -2x divide each side by -2
1.5 = x
y = -2x + 4 (1,2)
2 = -2x + 4 subtract 4 from each side
-2 = -2x divide each side by -2
1 = x
y = -2x + 4 (.5,3)
3 = -2x + 4 subtract 4 from each side
-1 = -2x divide each side by -2
.5 = x
Answer:
(1,2) (2,0) (3,-2)
Step-by-step explanation:
What I did to get those is plug in the numbers 1, 2, and 3 as values of X.
-2(1)+4
that gave me 2 as the Y value and now we have the coordinate (1,2).
-2(2)+4
that gave me 0 as the Y value and now we have the coordinate (2,0).
-2(3)+4
that gave me -2 as the Y value and now we have the coordinate (3,-2).

I agree with your first 2 answers and it might be a glitch cause that's how it was with my last school years online quizzes but I'm not positively sure about your third answer cause I haven't done the work yet... just make sure you took all the numbers and added them together then divided them by 8 cause there's 8 groups.
ngl I cant tell you what's wrong with the second question so I'm thinking somethings wrong with the coding but alrighty...
