I am not sure on this sorry ....... I think it's $5.00 .....
We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
Mathematics is the science that deals with the LOGIC of shape, quantity, and arrangement. for example algebra, analysis, number theory…. etc are all the examples of math.
This is simple. Just add the x and y values of each ordered pair to see which ones equals 2.
The answer is (-4, 6), (0, 2), (4, -2)
