Noah picked 3 kg of cherries. mai picked half as many cherries as noah. how many total kg of cherries did mai and noah pick?

Step-by-step explanation:

Cherries picked by Noah:

Cherries picked by Mai: , because she picked half as many cherries as Noah.

Therefore, the total number of cherries would be the sum of Noah's cherries and Mai's cherries:

So, they picked 4 and one half kilograms of cherries.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

maya’s expression will generate the wrong sum because she violated the commutative property.
