If you have to figures - Figure A and Figure B, and their linear scale factor is 2/5, then does that mean Figure B's sides are 2
/5 of Figure A's or Figure A's sides are 2/5 of figure B. Also, What is the ratio of the area of Figure A and Figure B?
1 answer:
Answer:
Correct answer: Figure A's sides are 2/5 of figure B.
Step-by-step explanation:
In the order the figures are given the proportion will be:
A : B = 2 : 5
By multiplying the outer and inner members of the proportion we get:
5 · A = 2 · B ⇒ A = (2/5) · B
That mean figure A's sides are 2/5 of figure B.
This means that the two units of figure A are referred to as the five units of figure B.

Answer:
b has 79,775 million
a has 241,275 million
Step-by-step explanation:
a has more than b
b+161,500 is a
b=b
b+b+161,500=321,050
2b=321,050-161,500
2b=159,550
b=159,550/2
b=79,775
a=b+161,500
a=79,775+161,500
a=241,275
X = 2y - 12....so sub 2y - 12 in for x in the other equation
3x + 4y = 14
3(2y - 12) + 4y = 14
6y - 36 + 4y = 14
6y + 4y = 14 + 36
10y = 50
y = 50/10
y = 5
x = 2y - 12
x = 2(5) - 12
x = 10 - 12
x = -2
solution is (-2,5) <==
