Which expression correctly represents "nine less than the quotient of a number and four, increased by three"?
c
tic
9-9

(x/4 + 3) - 9

Step-by-step explanation:

Break down each section of the question:

nine less is - 9

quotient(divison) of a number and four   x/4

increased by three  +3

let x be the number

(x/4 + 3) - 9

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
