Answer:

y=10

Step-by-step explanation:

\frac{4}{100}=\frac{y}{250}

cross-multiply, 4*250=100y

isolate the variable and solve for y, 1000=100y

divide 100 on both sides, 10=y

OLEGan [10]
This would depend on if we assume this is constant or exponential growth.  If it is linear then it would be:

600=3m+300

300=3m

100=m

A=100d+300

A(12)=1500 mi^2

If it is exponential:

600=300r^3

2=r^3

r=2^(1/3)

A=300(2)^(d/3)

A(12)=4800 mi^2

valentinak56 [21]
Well, the decrease was 130 - 39, that is 91

so... if 130 is the 100%, what is 91 of that in percentage?
well   \bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\

Answer:

x<2

Step-by-step explanation:

-1 + 6 (-1 - 3x) > -39 - 2x

-1 - 6 - 18x > -39 - 2x                  <--- multiply the 6 by 3

-7 - 18x > -39 - 2x

-7 - 18x + 2x > -39                      <--- add 2x to the other side

-7 - 16x > -39

-16x > -39 + 7                             <--- add 7 to the other side

-16x > -32

x < -32/-16

x < 2
