10984 rounded to the nearest thousand is 11,000
Answer:
Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.
Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.
So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is .
For this problem plug in the given x and y values:
For the first one: No
second one: No
third one: Yes
fourth one: No
Hey there! Hope I can help!
<span><span>P is the principal amount, $550.00.
</span><span>R is the interest rate, 3% per year, or in decimal form, 3/100 = 0.03.
</span><span>T is the time involved, 10 year(s) time period.
</span><span>So, t is the 10 year time period.
</span></span><span>To find the simple interest, we multiply 550 × 0.03 × 10 to get $165.00
</span>
<span>Then the interest is added onto the principal to figure the new amount after 10 years. </span>
<span>550.00 + 165.00 = 715.00 > $715.00 after 10 years.</span><span>
Hope this helps!

Answer:
79 electrons
Step-by-step explanation:
If it has 79 protons it will have a total proton charge of 79 so tho make the charge zero we need to add (79) electrons .Mathematically (1*79)+(-1*79)=0
