In a grade with 164 students, there were 18 more girls than boys. How many girls were in the grade?

91

Step-by-step explanation:

Let us set boys as x. Girls would then be x+18

Girls and Boys together would be x + x+ 18

Therefore,

x+x+18=164

2x+18=164

2x=146

x=73

Since girls are x + 18, they would be 73 + 18, or 91.

I hope this helps! :)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

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.
