Alan is making spaghetti for the picnic at the end of a 40-mile bike ride. Each
batch requires 3. jars of pasta sauce.
He plans to make 42 batches of
spaghetti. How many jars of pasta
sauce does he need?

126 jars

Step-by-step explanation:

Each batch requires 3 jars so the equation for 42 batches is:

42*3 = 126

i think its 126 but i may be wrong which i think i am sorry

Step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

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.
