Answer:

False

Step-by-step explanation:

It still has a solution, just not a solution with whole or exact numbers.

A system of equations would only have no solution if there were no points of intersection at all.

Noor brought 21 sheets of stickers. She gave 1/3 of a sheet to each of the 45 students at recess. She wants to give teachers 1 1
Tamiku [17]

Answer:

\frac{3}{2}t+15\leq 21

Step-by-step explanation:

Let t represent the number of teachers.

We have been given that Noor gave 1/3 of a sheet to each of the 45 students at recess.

Let us find the number of sheets given to students by Noor by multiplying the total number of students by the part of sheet given to each student.

\text{Number of sheets given to 45 students}=45\times \frac{1}{3}

\text{Number of sheets given to 45 students}=15

So, Noor gave 15 sheets to 45 students.

We have been given that Noor wants to give 1\frac{1}{2}=\frac{3}{2} sheet to each teachers, so the number of sheets given to t teachers will be \frac{3}{2}t.

As Noor has bought 21 sheets, so the number of sheets given to students and t teachers will be less than or equal to 21.

We can represent this information in an inequality as:

\frac{3}{2}t+15\leq 21

Therefore, the inequality \frac{3}{2}t+15\leq 21 represents the number of teachers ,t, Noor could give sheets of stickers too.

A dishonest shopkeeper has two false balances. One balance weighs 10% more while
sleet_krkn [62]

Answer:

Shopkeepers gain just by weighing is 22.22%

Step-by-step explanation:

Explanation:

Assume that the shopkeeper bought x units of goods i.e. actual weight of goods.

As the balance used to buy goods weighs 10% more, he actually bought x×110100=1.1x weight units i.e. although the shopkeeper paid for x units, he actually bought 1.1x units by weight.

Now he has 1.1x units of goods, but for selling he uses another balance, which actually measures 10% less i.e. 1−0.10=0.9 units for each unit weight of goods sold.

So while selling 1.1x becomes 1.1x0.90=1.2222... units.

Hence, shopkeepers gain just by weighing is 22.22%
