Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.

Which of the following is the conjugate of a complex number with 2 as the real part and 7i as the imaginary part? (5 points)

lisov135 [29]

The complex conjugate of 7i is −7i The complex conjugate of a number

z is a number with opposite imaginary part.

So if z=a+bi then conjugate is: ¯z=a−bi for any a,b∈R

We can note, that if we represent all complex numbers in coordinate system, then for any number: the number z and its conjugate ¯z are symetrical according to "real part" axis.
