How can estimating be helpful

1 answer:

6 0

It helps you narrow down to a smaller answer for example there is pi, (3.14159265359) and there is more and more to that number. It is now estimated to 3.14 because it would be almost impossible to work with pi if it wasn't estimated

Jerome will also order t-shirt for the volunteer he will order both adults and child t-shirt . Adults t-shirt are $5 child t-shi

Gala2k [10]

Answer:

$A\geq 200...(1)$

$5A+2.50C\leq 1500...(2)$

Step-by-step explanation:

Let A represent number of adult t-shirts and C represent number of child t-shirts.

We have been given that adults t-shirt are $5 child t-shirt are $2.50, so cost of A adult t-shirts would be $5A$ and cost of C child t-shirts would be $2.50C$ .

We have been given that Jerome need at least 200 adults t-shirt. This means the number of adult t-shirts should be greater than on equal to 200.

We can represent this information in an inequality as:

$A\geq 200...(1)$

We are also told that Jerome will spend no more than $1500 on t-shirt. This means that cost of A adult t-shirts and C child t-shirts should be less than or equal to 1500.

We can represent this information in an inequality as:

$5A+2.50C\leq 1500...(2)$

Therefore, our required system of inequalities would be:

$A\geq 200...(1)$

$5A+2.50C\leq 1500...(2)$

-144 is -1 x 2a x 3b what is the sum of a+b?

BigorU [14]

-144= -1×2a×3b
144=2a×3b
144= 6ab
24= ab

a,b could b any two factors that have a product of 24
For example a,b could = 6,4 or 8,3 or 24,1

Answer:
This question is tricky because it could have multiple answers: for example is a,b= 6,4 then a+b= 10, but if a,b=24+1=25. So, the answer is that the sum of a+b varies depending on which 2 factors of 24 a and b are equal to. Does this make sense?
