Answer: 0.27£
Explanation:
9 apples + 9 bananas = 2.43
9(apple + banana) = 2.43
Apple + banana = 2.43/9
Apple + banana = 0.27£
Therefore, the cost of an apple AND a banana is 0.27£
Simplify both sides then isolate the variable and it gives you y=3.6
Both mean to factor, I've never heard of a difference
Answer:
4% sales tax
Step-by-step explanation:
Take the original costs and subtract it from the price after sales tax.
$84.24-$81= $3.24
Divide 3.24 by 81
this gives you .04, now either multiply by 100 or move the decimal two places to the right to convert the decimal to a percentage.
Simplify 4^4 to 256
256 + 1/2 = 256.5
Simplify 256 + 1/2 to 513/2
513/2 = 256.5
Since both sides equal, there are infinitely many solutions.
