5(2x-8)=90
10x-40=90
add 40 to both sides
10x=130
divide 130 by 10
and the answer Is x=13

Answer: x=13

Step-by-step explanation:

distributive property: a(b+c)=ab+ac

addition property of equality is adding the same number to both sides of an equation does not change the equation.

divide by 5 both sides of an equation.

5(2x-8)/5=90/5

simplify.

2x-8-18

add 8 both sides of an equation.

2z-8+8=18+8

simplify.

2x=26

divide by 2 both sides of an equation.

2x/2=26/2

simplify.

26/2=13

13*2=26

2*13=26

x=13

Hope this helps!

Thanks!

Have a great day!

Samantha wants to use her savings of 1150 to buy shirts and watches for her family. The total price of the shirt she bought was

ioda

Answer-

The maximum number of watches that Samantha come by with her savings is 10.

Solution-

The amount of money Samantha has in her savings account = $1150

She wants to buy shirts and watches.

Cost of one shirt = $84

Cost of each watch = $99

Let she can buy maximum of x watches, so the net price of the watches is $99x.

Then,

$\Rightarrow 99x+84=1150\\\\\Rightarrow 99x=1150-84\\\\\Rightarrow 99x=1066\\\\\Rightarrow x=\dfrac{1066}{99}\\\\\Rightarrow x=10.77$

As the number of watches can not be in fraction, so at most she can buy 10 watches.

Enter the equations of the asymptotes for the function f(x). f(x)= 3/x−7 + 2

Alexxx [7]

Answer:

x = 7, y = 2

Step-by-step explanation:

I assume it is 3/(x-7) + 2.

When x = 7, there is an asymptote because it is undefined.

When y = 2, there is also one, because 3/(x-7) is never 0.

These are the only ones.
