Hi,
The answer should be y^2, since (y^5)/(y^3) = y^(5-3)

It’s y^2. When dividing exponents, you subtract the second one (“under the line”) from the first one (on top). Since 5-3=2, it’s y2.

6(x-4)=7(x+3) <br> Show your work
sergeinik [125]

Answer:

do distributive property on both, so multiply 6•x and 6•-4. then multiply 7•x and 7•3.

so it'll basically be 6x - 24 = 7x + 21.

then add 24 to both sides so: 6x - 24 + 24 = 7x + 21 + 24. since -24+24=0 it'll be 6x = 7x + 21 + 24.

then add 21 + 24 and that will be 45.

so 6x = 7x + 45

then subtract 7x from both sides 6x - 7x = 7x + 45 - 7x

that'll be -x = 7x + 45 - 7x

combine like terms (7x - 7x) = 0

so -x = 45

and since x can't be negative, do the opposite signs

so instead of -x = 45, make it x = -45

Hope it helped! (sorry that's its very long just wanted to show u the steps just in case)

A cell phone charger costs $21. There is a 10% discount this week only. The sales tax is 9%. What is the total of the phone char
Marizza181 [45]

Answer:

$20.60

Step-by-step explanation:

Price before discount = $21

Discount rate = 10% or 0.1

Discount in dollars = 0.1* 21 =  $2.1

Price after discount = $21 -$2.1 = <em>$18.90</em>

If sales tax is 9% or 0.09

amount of tax  will  be = 0.09 * 18.90 = <em>$1.701</em>

Total price of the phone including taxes = Price before tax + tax amount;

Total price = 18.90 +1.701

                 = 20.601

Therefore total price will be $20.60

Solve the systems of equations 9x+5y=41 and x+y=9 by combining the equations
Sholpan [36]

Step-by-step explanation:

multiplying the 2nd eqn by 9 we get,

9x+9y=81

then,subtracting 1st and 2nd eqn

9x+5y=41

9x+9y=81

- - -

__________

0. -4y=-40

we get y = 10

then we get x=9-y

x=9-10

x= -1

so x is -1 and y is 10
