Jennifer Lopez met her 9 cousins at a family reunion. The number of male cousins (x) was 2 less than the number of females cousi
vesna_86 [32]
We define the variables first:
 x = number of male cousins
 y = number of females cousins
 We write the system of equations:
 x + y = 9
 x = y-2
 We solve the system:
 Equation 1:
 x + y = 9
 (y-2) + y = 9
 2y-2 = 9
 y = 11/2 = 5.5
 Equation 2:
 x = 5.5-2
 x = 3.5
 Answer:
 Although physically it does not make sense, mathematically the answer is:
 number of male cousins = 3.5
 number of females cousins = 5.5

ALLL MY POINTS PLSSS HELPPPPP
Rama09 [41]

Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0  

Discriminant = 4 - 4(K)(-1) = 4 + 4K  

For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.  

The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.

Can you solve this problem? <br><br> Don't forget to show your work :) thanks!
Rzqust [24]
Well, start from 100% and work backwards.

It takes 5600 years to get to 50%
Another 5600 years to get to 25%
And a bit under another 5600 to get to 15% (another 5600 years would get it down to 12.5%)

Add the first two 550s to get 1120, and add about 5,000 and see which answer is closest.
In this case, D is closest at 15!w29

There are more exact ways of solving, but for a multiple choice this is faster and efficient nonetheless

Aliun [14]

Answer: Girls: 20

Boys: 30

Step-by-step explanation: 40% of 50 is 20, which means there are 20 girls.

Subtract 50-20 to get the number of boys, which is 30.
