Answer:

x = 12

Step-by-step explanation:

The ray from the vertex to the base is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

$\frac{x}{9}$ = $\frac{4}{3}$ ( cross- multiply )

3x = 36 ( divide both sides by 3 )

x = 12

Answer:

f(x) = 3 + 5x

Step-by-step explanation:

For this problem, we can see a simple pattern whereas x increases by 1, y is increasing by 5.

This means that f(0) = 3.

And to create the function, we simply use f(0) summed with the increasing 5 multiplied by the input x.

Hence, we will create the function equation:

f(x) = 3 + 5x

Cheers.

Jen wants to buy a dress that originally had the price of $33, but now it is on sale 10% off. How much will Jen pay for the dres

You multiply 33 by 0.9 because it's minus 10% (0.1) and the answer is $29.7

How many liters of a 20% alcohol solution must be mixed with 60 liters of a 90% solution to get a 80% solution?

leva [86]

x = liters of 20% solution

Mixing the 20% solution with the 60 L of 90% solution gives a new mixture with volume (x + 60) L. Each L of the 20% solution contributes 0.2 L of alcohol and thus a total of 0.2x L of alcohol, while the 60 L of 90% solution contributes 54 L of alcohol.

We want the concentration of the new mixture to be 80%, so we require

$\dfrac{0.2x+54}{x+60}=0.8$

Solve for x:

$0.2x+54=0.8x+42$

$12=0.4x$

$\implies\boxed{x=30}$

So you will need 30 L of the 20% solution.
