Answer:
x = 26
Step-by-step explanation:
Since the triangle is right, use Pythagoras' identity to find x
x² = 24² + 10² = 576 + 100 = 676
take the square root of both sides
= 
, hence
x = 26
so 15% off is 149.85 which makes it 849.85 then you add sales tax which is 79.92 and your cost is 929.07
Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
Answer: There is no proof that the population increased by 10% every year. it is possible the first year increased by 8 the first year then 12 the next, giving a 20% increase.
Extra: the answer the the first and second year is x you must figure the x out if you want the answer to those
