What you want to do is write the numbers with similar bases, and then you can cross the bases off. Like this:

25^x+2=125^3x+4
5^2(x+2)=5^3(3x+4)
Now you can cross the similar bases off.
2(x+2)=3(3x+4)
2x+4=9x+12
7x=-8
X=-8/7

(-2/3)*(-2 1/4)*(3/4)   Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4)   Then you multiply the numerators with numerators and                                             denominators with denominators

(-2*-9*3)           negative times negative is positive, so the negative sign is gone
-------------    
(3*4*4*)              The lines (-----) is the line of the fraction 

54/48            This is the product of this multiplication, now you need to simplify 
                        by reducing the numbers of the fraction

9/8         And that would be the answer

<span>"ratio of princesses to celebrities is 3:1"

The are 3 more times princesses as celebrities.

</span>"<span>The ratio of superheros to princesses is 5:4"

For each 4 princesses, there are 5 superheroes.

For 1 celebrity, there are 3 pincesses.

For 4 celebrities, there are 12 princesses.
For 12 princesses, there are 15 superheroes.

The ratio of celebrities to princesses to superheroes is
4:12:15 or 4x:12x:15x

Add them: 4x + 12x + 15x = 31x

31x = 93

x = 93/31 = 3

Celebrities: 4x = 4(3) = 12
Princesses: 12x = 12(3) = 36
Superheroes: 15x = 15(3) = 45

Answer both question for 20 points and brainliest
Dmitrij [34]

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

V=\frac{1}{2} bhl

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct
