Answer: 280 dollars
Step-by-step explanation:
if the IPOD is 350,
10% out of 350 is 350/10=35
20% is 35*2=70
the price will be 350-70=280
He built 15 robots (4 + 8 + 3) = 15

Answer:
Combine like terms
Step-by-step explanation:
The first step in such equations is to simplify the equation which is done most often by combining like terms, and by combining like terms i mean for example:
1 + 5 + 3x = 4y + z
You will combine the like terms (those that can be added or subtracted):
6 + 3x = 4y + z
In our example, combining terms would be adding 2x/3 and 1x/3 to give
3x/3 + 2 = 5
The equation is now simple and easy to solve as you simplify 3x/3 to 1x and then proceed to rearrange the equation to yield the value of x
Hope this helps!

Use Pythagorean thrm
17^2+10^2=21^2
