Answer:
Step-by-step explanation:
Commission = 2% of 2,50,000
= Rs. 5000
Let x be the unknown number of years.
Let C be Chris' age and J be Jenny's age.
Then J+x = 2(C+x)-7
... describes this situation.
4+x = 2(2+x) - 7
4+x = 4 + 2x - 7
x = 2x -7 becomes 7=x
In 7 years, Jenny will be 7 years younger than twice Chris' age.
Check: Is this true? 4+7 = 2(2+7)-7
11 = 18-7, or 11=11 TRUE
This is the equation: 3x-2=5x+15
<span>you combine like terms: 3x-3x-2=5x-3x+15 </span>
<span>the 3x on the left cancles out: -2=2x+15 </span>
<span>subtract 15 on both sides: -2-15=2x+15-15 </span>
<span>the 15 on the right cancles out:--17=2x </span>
<span>divide by 2: -17/2=2x/2 </span>
<span>x equals negative 8.5: x=-8.5</span>
3/4 - 5/9 .....common denominator is 36
27/36 - 20/36 =
7/36 <==
(x-6.5)^2 = 60.25 is the answer
