An ounce is equal to about 28 g. If 1 g of soil contains 2.5 billion bacteria, how many bacteria are in 1 oz of soil?

Nimfa-mama [501]

Answer:

About 700 billion bacteria

Step-by-step explanation:

Given

$1oz \approx 28g$

$1g = 25\ billion\ bacteria$

Required

Number of bacteria in 1 oz

$1g = 25\ billion\ bacteria$

Multiply both sides by 28

$28 * 1g = 25\ billion\ bacteria * 28$

$28g = 700\ billion\ bacteria$

Recall that

$1oz \approx 28g$

This means:

$1oz \approx 700\ billion\ bacteria$

-4(3-2x)+2x=2x-8 pls help me will give BRAINLIEST

nikdorinn [45]

Answer:

x = -1/2

Step-by-step explanation:

multiply the -4 to all in parentheses

-4(3-2x) +2x =2x -8

-12+8x +2x =2x-8

isolate x by moving whole numbers to other side of equal sign and x to the other side

8x +2x -2x = -8+12

8x = -4

divide by 8 to isolate x

x= -4/8

simplify

x= -1/2
