Answer:
2 1/10 kilograms
Step-by-step explanation:
2 9/10 minus 4/5
Make the 4/5 have the same denominator as 9/10
2 9/10 minus 8/10
Subtract
2 1/10
PLZ MARK ME BRAINLIEST.
Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.
For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>

Multiply then add
Answer:
3.4121 * 10 ^4
Step-by-step explanation:
34,121 is same as
3.4121 * 10 ^4
because the first number has to be between 0 and 10 and if you move the decimal 4 places to the right you got the initial number
Answer:
n= 1/9
Step-by-step explanation:
3/n 3/6=3/2
Simplifies to
1/6n = 3/2
Cross-multiply.
1/6n = 3/2 - (1)*(2)=3*6n
2=18n
Flip the equation
18n=2
Divide both sides by 18
18n/18 = 2/18
n=1/9
Hope it's right :)
