To solve this problem we have to find what 85% of 40 is, and then add that value to 40.
40 * 0.85 = 34
34 + 40 = 74
74 is the result when 40 is increased by 85%.
-a+7=2a-8
-a+a+7=2a+a-8 add a on both sides
7+8=3a-8+8 add 8 on both sides
15/3=3a/3 divide 3 on both sides
a=5 solution
Answer:
6
Step-by-step explanation:
(n- 1)(n)( n +1)=210
n(n²-1)=210
n³-n= 210
n³-n-210=0
let n = 6 => 6³-6-210 = 216-6-210 = 0 (true)
so, n = 6
