Answer:
<h2>
Most explained:</h2>
40% = 100%
15 = (100% - 15% = 85%) 85% in Alaska
California = 15% of 40 = (0.15 x 40) = 6
Alaska = 85% of 40 = (0.85 x 40) = 34
<h2>The simple way (or the way i found it simple):</h2>
<h3>40 - 15 = 34</h3><h3>15% of 40 = 6</h3>
<h3>(I found the simple way after i solve the first way)</h3>
Bye, i hope this helps.

208 is the answer
add all the numbers multiply till 800
multiply 52 by the same number and you'll get the answer
It would be 60. He sold his painting for 50 which was 10 less that the original price. So 50+10=60
Answer:
c: x=2
Step-by-step explanation:
5x-3= 13-3x
+3 +3
5x=16-3x
+3 +3
8x=16
divide all of it by 8 and thats how you get your answer
a = amount (in oz) of solution A
b = amount of solution B
The scientist wants a mixture of 110 oz, so
a + b = 110
Solution A consists of 65% salt, so each ounce of solution A contributes 0.65 oz of salt; similarly, each ounce of B contributes 0.9 oz. The mixture is supposed to consist of 75% salt, which amounts to 0.75 * (110 oz) = 82.5 oz of salt. So
0.65 a + 0.9 b = 82.5
Solve for a and b:
b = 110 - a
0.65 a + 0.9 (110 - a) = 82.5
0.65 a + 99 - 0.9 a = 82.5
0.25 a = 16.5
a = 66 ==> b = 44
