A school cafeteria has 30 boxes of Wheaty Squares cereal and 20 boxes of Mighty O's cereal. Each box has the same number of ounces of cereal. Write an expression to
represent the total ounces of cereal. Then simplify it to create an equivalent expression.

50e=t

Step-by-step explanation:

Wheaty Squares = w

Mighty O's = m

ounces in each box = e

total ounces of cereal = t

w+m=30+20=50

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

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
