A 12-ounce bottle of shampoo lasts Enrique 16 weeks. How long would you expect an 18-ounce bottle of the same brand to last him?

It will last him 24 weeks. You would divide 12 by 16 and get .75 from that. That means he uses .75 ounces a week. Divide 18 by .75 and you get 24. It will last him 24 weeks

How do you do this problems?

x = 6

Step-by-step explanation:

It's based on similarity of triangles

DEF ~ △XYZ

$\implies \mathsf{ \frac{DE }{ XY } = \frac{EF}{YZ} = \frac{ FD}{ZX}}$

The sides should be taken in order, like the triangles start with DE and XY so, we'll proportionate DE and XY and then the next two sides and so on.

I'm using $\mathsf{ \frac{DE }{XY } = \frac{EF}{YZ} }$ to get the value of x.

[You can use any two fractions out of the three given above. ]

$\implies \mathsf{ \frac{10}{x - 1} = \frac{8}{4} }$

$\implies \mathsf{ \frac{10}{x - 1} = 2 }$

$\implies \mathsf{ 10 = 2 (x - 1) }$

$\implies \mathsf{ 10 = 2 x - 2 }$

$\implies \mathsf{ 10 + 2= 2 x }$

$\implies \mathsf{ 1 2= 2 x }$

$\implies \mathsf{ x = 6 }$

Hence, the value of x is 6.

If you bought something for $372.60 including an 8% tax, what was the price before the tax?

Dvinal [7]

Answer:

$345

Step-by-step explanation:

<u>Let the price before tax be x, then we have:</u>

x + 8% = 372.60
x + 0.08x = 372.60
1.08x = 372.60
x = 372.60 / 1.08
x = 345

The initial price was $345
