Answer:</h2>
- 9 3 x 7 5
<h2>
Step-by-step explanation:</h2>
To get the combination that would yield the greatest result if the true number are multiplied,
<em>i. multiply each given combination</em>
73 x 95 = 6935
79 x 53 = 4187
97 x 35 = 3395
93 x 75 = 6975
<em>ii. get the largest result from the results calculated above in (i)</em>
The greatest of the results is 6975, therefore the digits should be placed like so;
<u> 9 </u> <u> 3 </u>
<u> 7 </u> <u> 5 </u>

There would be 450 rabbits last year.
Since 900 is double 450, 200% of 450 is 900. (450 would be 100%, so you would double it).
Answer:
10,500
Step-by-step explanation:
Decimal: It’s easier to work with the numbers You can add, subtract, multiply and divide in your head (for the most part) instead of having to find common denominators and things like that.
Fraction: You can put repeating values in fraction form to represent them in a simpler way, as opposed to having to put the line over the repeating digits if it were in decimal form.
Power: Powers are just condensed forms of repeated multiplication, so they save space/time and you can use certain properties with some powers that allow you to multiply and divide them instantly.
Scientific notation: This is good when you’re dealing with numbers that have a lot of digits/place value. That can become confusing, so scientific notation is a way we can represent these numbers clearly and more condensed (takes less space/time).
Answer:
(a) (6, 2)
Step-by-step explanation:
The system of equations has one of them in y= form, so it lends itself to solution by substitution.
__
Using the equation for y to substitute into the first equation, we have ...
2x -y = 10
2x -(-1/2x +5) = 10 . . . . . substitute for y
2x +1/2x -5 = 10 . . . . . eliminate parentheses
5/2x = 15 . . . . . . . . . add 5, collect terms
x = 6 . . . . . . . . . . . multiply by 2/5
Using the equation for y, we have ...
y = -1/2(6) +5 = -3 +5
y = 2
The solution is (x, y) = (6, 2).
