Answer:
6.5
Step-by-step explanation:
Change the divisor 2.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equation:
25 into 162.5 equals 6.5
Calculated to 1 decimal places.
I believe the answer would be
-1 1/3
37 short-sleeved shirts were sold and 30 long-sleeved shirts were sold
Step-by-step explanation:
Let s be the number of short-sleeved shirts
and
l be the number of long sleeved-shirts
Then according to given statements

From eqn 1:

Putting in equation 2:

Dividing both sides by 11

Putting l=30 in equation 1

Hence,
37 short-sleeved shirts were sold and 30 long-sleeved shirts were sold
