−3y−(8y+1)
Distribute the Negative Sign:
=−3y+−1(8y+1)
=−3y+−1(8y)+(−1)(1)
=−3y+−8y+−1
Combine Like Terms:
=−3y+−8y+−1
=(−3y+−8y)+(−1)
=−11y+−1
Answer:
The mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs.
Step-by-step explanation:
This questions implies that there is a need to fill in mathematical symbols that will this a true a equation.
A true equation can be described as situation whereby there the same values on the either sides of the equal sign "=". For instance, 5 + 1 = 6 is a true equation. Also, 4 * 2 = 8 is a true equation.
As regards this question, the mathematical symbols that are filled in between the numbers to make it a true equation are the multiplication signs. When the multiplication signs are filled in between the numbers, we have the following true equation:
2802 * 1811 * 123 * 441 * 3633 * 1/3 * 32^2 * 205 = 69,972,637,305,761,000,000
Answer:
The answer to your question is: letter A
Step-by-step explanation:
Rules for using scientific notation:
1.- The number before the decimal point must be between 1 and 10.
2.- Determine the exponent
3.- It must be in decimal format, ( x 10)
A 3.8*10^12 This number is in correct scientific notation.
B 33.8* 10 This number is incorrect, because before the decimal point the number must be between 1 and 10.
C 3.8 *20^8 This number is incorrect because the power must be 10 not 20.
Answer:
Whats the question?
Step-by-step explanation:
Answer: 46
Step-by-step explanation:
percentage scored = 92
number of correct question = x
total number of questions = 50
The formula for calculating the percentage scored
= number of correct question / total number of questions x 100
That is
92 = x
cross multiplying :
x
dividing through by 100 , we have
Therefore, she got 46 questions right
