What you do is take two of the numbers and add them together then you take the sum (what you get after you add the two numbers) then add them to the third number and if there are more numbers then you can take the sum of the three numbers and add the fourth and so on
Answer:
7) 7.8*10^0
8) 3.2
*
10
^-7
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
D. -6m²n² + 10m²n + 8mn² - 10mn
Step-by-step explanation:
(-7mn + 8mn² - 8m²n²) + (10m²n + 2m²n² - 3mn)
Apply the distributive property to remove the parentheses
-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn
Combine like terms together and arrange in standard form
-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn
-8m²n² + 2m²n² + 10m²n + 8mn² - 7mn - 3mn
-6m²n² + 10m²n + 8mn² - 10mn
Answer:
20/30 (2/3)
Step-by-step explanation:
1 5/6 in improper form is 11/6 and 1 2/5 in improper form is 7/5. We need to find an LCM (Least Common Multiple). The LCM in this case is 30. 11/6 times 5 is 55/30 and 7/5 times 6 is 35/30. 55/30 minus 35/30 is 20/30. That could also be simplified to 2/3.
