-3(2/5x-2)=18
multiply -3 by 2/5 and my -2
-6/5x + 6 = 18
subtract 6 from each side
-6/5x = 12
divide by -6/5, multiply 12 by -5/6
x = -10
It’s 20+40=60
24+37=60 rounding to the nearest 10 is 60
Answer: -3, -2.5, -1, 2, 5.
Explanation:
The number line goes from the smallest number to the largest number. As an example you may ask why -3 is smaller than -1 even though it looks larger. This is because it actually isn’t since it is negative. When a number is negative, the higher the number are the smaller it is. One more example could be that -10 is smaller than -5.
Answer:
Neon: 0
Oxide: -2
Copper: 2
Tin: 0
Step-by-step explanation: To solve you must add/subtract the numbers to get the charge, for example if its -30 charge from electrons and 10 charge from protons, -30 + 10 = -20 therefore the charge is -20
