Devon’s teacher requires that students show each step in solving a problem. devon wrote the following when solving the equation x- 7 = 20: x -7 = 20 x -7 = 20 + 7 x = 27 the teacher said that devon’s work was not shown correctly. why? a) devon’s final answer should be 13 b) devon should have shown that he added 7 to both sides c) devon should have shown that he subtracted 7 from both sides d) devon should have shown that he added 7 to the left side only

B) Devon should have shown that he added 7 to both sides

Step-by-step explanation:

x-7 =20

add 7 to each side

x-7+7 = 20+7   NOT x-7 = 20+7

x=27

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
