7 0

Answer:

1100 %

Step-by-step explanation:

% increase = Increase/original × 100%

Increase = 3000 – 250

Increase = 2750

% increase = 2750/250 × 100

% increase = 11 × 100

% increase = 1100 %

The population increased 1100 % .

Circumference=2\pi r\\C = 2 \pi (2.5)\\C = 15.708

What is -5n+7&lt;57 and 6n+2&lt;8
pishuonlain [190]

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1
