Answer:
The small box contains 21 cans
<em></em>
Step-by-step explanation:
Represent the small box with S and the large with L.
For Estelle:
For the boy:
Required
Determine the cans in the small box
--- (1)
--- (2)
Divide (2) through by 4
Make L the subject
Substitute 46 - S for L in (1)
Open bracket
Collect Like Terms
Divide both sides by 2
<em>Hence, the small box contains 21 cans</em>
Answer: is very simple 26
Step-by-step explanation:
multiply and then divide the both numbers
Answer:
The percentage decrease = 0.9%
Step-by-step explanation:
Using the formula
Percentage Decrease = [ (Initial Value - Final Value) / |Initial Value| ] × 100
= [(9.80 - 9.71 ) / (9.80)] × 100
= [0.09 / 9.80] × 100
= 0.009 × 100
= 0.9%
Therefore, the percentage decrease = 0.9%
The answer is: " 95 km " .

Don't get too involved in the 'simplify' part just yet.
It doesn't mean make the problem easier.
It means that when you have the answer, make sure it's in simplest form.
That's why it says "Simplify your answer".
Notice that that's the 2nd instruction.
There's nothing to simplify until you have an answer.
The first thing you have to do here is find the area of a triangle.
Do you remember that formula ?
I'll bet you do.
The area of a triangle is (1/2) · (length of the base) · (height) .
The height and the length of the base are given, right there
in the picture. Take those, and use them to find the area.
Once you've multiplied the binomials, don't forget about the (1/2).
Finally, you have a trinomial for an answer.
Put the big sweet cherry on top: Factor it !
I think that's the 'simplify' part.
You may be surprised.
I was when I worked it out just now ... just for you.
