Answer:
Number of small boxes shipped = 10
Number of large boxes shipped = 12
Step-by-step explanation:
Let x be the number of small boxes
and
y be the number of large boxes
According to the first statement, a total of 22 boxes were shipped
Equation 1 will be:
x+y=22
And
According to 2nd statement, Total weight was 1350 and we know the weight of one small box is 45 and large box is 75
So equation 2 will be:
45x+75y=1350
We will use the substitution method for solving the equation
So from equation 1

Putting the value of x in eqn 2

Putting the value of y in eqn 1

So,
Number of small boxes shipped = 10
Number of large boxes shipped = 12 ..

Answer:
81-25k²
Step-by-step explanation:
We need to write the expression for "The quantity 81 minus 5k, squared".
Square of any number x is given by x².
Square of 5k is given by : (5k)²= 5²×k²=25k²
Now subtract 25k² from 81.
It means we get : 81-25k². It is required expression.
