Answer:
Step-by-step explanation:
triángulo 30°-60°-90°
Okay, so:
You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.
So,
423*.1
(you have to turn the percentage into a decimal; 10%= .10
423*.1= 42.3
So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.
I hope this helps!

Answer:
lets start with the easy equation. X+Y=60. so we take 60 and subtract Y to get X by itself. meaning X = 60-Y. every time we see X replace with (60-Y).
X + 5Y = 100 change to
60-Y+5Y = 100
5Y - Y = 4y.
60+4Y = 100. 100 minus the 60 = 40. 4Y=40. divide by 4. Y = 10. ok so now we solve for X. X + Y (or 10) = 60. 60-10 = 50. X = 50.
Step-by-step explanation:
Answer:
56 + 23 + (-5)
you want to expand the bracket first
23 + (-5)
23-5 = 18
56 + 18 = 74
a) 74
6 + 24 + (-2)
24 - 2= 22
6 + 22 = 28
b) 28
3 + 7 + (-42)
7 - 42 = -35
3 - 35 = -32
c)-32
( 8 + 1 ) + (-3)
+(-3) = -3
9 - 3 = 6
d)6
( 7 + 10 ) + ( 3 + 1 )
17 + 4 = 21
e)21
59 + 2+ (-6)
2+(-6) = 2-6 = -4
59-4
55
f)55
41 + ( -89)
41 - 89
= - 48
g)-48
( - 13) + 33
-13+33
= 20
h) 20
