Answer:
The weight of the larger box is 18.75 kg
The weight of the small box is 6.75 kg
Step-by-step explanation:
Let
x -----> the weight of large box
y ----> the weight of small box
we know that
The system of equations is equal to
9x+7y=216 -----> equation A
3x+5y=90 -----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (18.75,6.75)
therefore
The weight of the larger box is 18.75 kg
The weight of the small box is 6.75 kg
Answer:
it's equivalent to
9/4 = 2.25 or 2+1/4
Answer:2.25
Step-by-step explanation:
Round to the nearest hundredth or cent.
We are given original cost of the item excluding tax = $3.
Sale tax is 4.4% of the original cost of the item.
4.4% of 3 is = 0.044 × 3 = 0.132.
We need to round it to the nearest hundredth or cent.
So, we need to round 0.132 to two decimal places.
Therefore, 0.132 can be round to 0.13.
We needed to find the tax amount on the original cost of the item.
