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

Mr. Soto plans to open a savings account. Four banks offer the annual interest rates shown. Which list shows these interest rate
Delvig [45]
Ok, so IDK if I'm about to do this problem right, but here we go;


so first, lets change these all to decimals (I more of a decimal gal)

3 1/2 = 3.5
3 2/3 = 3.6666 (repeating)
3 3/5 = 3.6
3 3/8 = 3.375

So now, just order them from greatest to least.  

3.66666, 3.6, 3.5, 3.375.  

Now, change them back to fractions.  
3 2/3, 3 3/5, 3 1/2, 3 3/8


So, if I'm correct, the answer is 3 2/3%, 3 3/5%, 3 1/2%, 3 3/8%
Hopefully I solved your problem!

Find the measure of angle A.<br> 66°<br> x +49<br> x+83
liubo4ka [24]

Step-by-step explanation:

Since , internal sum of angle of triangle is 180°

So,

66 + x +49 + x+83 = 180

or, 198 + 2x = 180

or, 2x = 180 -198

or, 2x = -18

hence, x = - 9

Now angle A = x + 49

= (-9) + 49

= 40

<u>Hence </u><u>measure</u><u> </u><u>of </u><u>angle </u><u>A </u><u>is </u><u>4</u><u>0</u><u>°</u><u>.</u>
