Answer:

Step-by-step explanation:

CD is an angle bisector and divides the opposite side into segments which are proportional to the other 2 sides, that is

$\frac{BC}{AC}$ = $\frac{BD}{AD}$ , substitute values

$\frac{4}{3}$ = $\frac{x}{2.25}$ ( cross- multiply )

3x = 9 ( divide both sides by 3 )

x = 3 → D

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 these expressionis is <br> equivalent to x^4-5x+3/x^2+7

bonufazy [111]

Next time, please list the possible answer choices. Without them, all I can do is to attempt this problem without having those choices as guidelines.

I must assume that your expression x^4-5x+3/x^2+7 actually meant:

5x + 3

x^4 - ---------------

x^2 + 7

and I assume that this result was one of the several possible answer choices.
