Answer:
8.3
Step-by-step explanation:
8.25 has to round up because of the five making it 8.3
Answer:The term X is a variable that takes the place of any number. ... If X stands for the number 13 then 2 times 13 is equal to 13 plus 13 which gives 26 when added. Similarly 2 multiplied by X results to X plus X which means a number added to itself since multiplication is a repeated addition. So 2X = 2 * X = X + X = 2X.
Step-by-step explanation:hope that helps
We can focus on each part separately, first the numbers:
-3 times (5 squared)
-3 times 25
= -75
This rules out the last two options
Next let’s focus on the x terms:
x^3 times (x^5 squared)
When raising a term that is already raised to a power by another power, you multiply the powers, in this case 5 times 2 = 10
x^3 times x^10
When multiplying numbers with the same base, you add the powers
=x^13
So the answer must be B but we can check the y terms just to make sure
y^2 times (y^4 squared)
y^2 times y^8
=y^10 which matches answer B
67.82 x .075 = 5.0865 rounded to 5.09. 5.09+ 67.82 = $72.91. There's your answer
