Answer:

You check one-step equations by: Once you've solved it, you've found the value of the variable that makes the equation true. To solve one-step equations we do inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself

the width of a rectangle is 2/3 the length. the perimeter of the rectangle is 15 centimeters. what is the length of the rectangl

tester [92]

Lenght is 4 1/2 cm
P=2L +2W
15cm = 2L + 2(2/3L)
15cm = 2L + 4/3L
15cm = 2 4/3 L
15cm ÷ 2 4/3 = 2 4/3L ÷ 2 4/3
4 1/2cm = L

Check
P=2L +2W
P=2(4.5) +2(3)
15= 9 +6
15=15

An environmental (soil) sample obtained from a temperate region was transferred to a liquid growth medium and incubated at 30°C

ad-work [718]

Missing Question:

The question was missing information. I have found the question online and attaching it here for convenience.

Answer:

Option D

Explanation:

From the picture, we can see two types of bacteria (i.e. A and B), therefore it is not a pure culture.

We can not predict whether any culture has been lost during incubation.
A and B are different organisms.

Hence, the only correct option is D, which states:

"Identification of microbial types in the environmental sample could have been attempted without culturing anything."
