$1.50x + 3 = 13.50$

If x=number of chores, then you can solve for x to see how many chores Jane would have to do in order to earn enough money for her cd.

1.50x+3=13.50
subtract 3 from both sides
1.50x=10.50
divide both sides by 1.50
x=7

32^{3x+5}=8^{x−1} I need help plz

Elena L [17]

Answer:

The value of x for the given expression is $\dfrac{- 7}{3}$

Step-by-step explanation:

Given as :

The expression is

$(32)^{3 x + 5}$ = $(8)^{ x - 1}$

Now,

∵ $(2)^{5}$ = 32

And $(2)^{3}$ = 8

So, $(2^{5})^{3 x + 5}$ = $(2^{3})^{x - 1}$

Or, $2^{15 x + 25}$ = $2^{3 x - 3}$

<u>Here , on both side base is 2 , so we remove common base 2</u>

∴ Equation can be written as

15 x + 25 = 3 x - 3

Or, 15 x - 3 x = - 25 - 3

Or, 12 x = - 28

∴ x = $\dfrac{- 7}{3}$

So, The value of x = $\dfrac{- 7}{3}$

Hence, The value of x for the given expression is $\dfrac{- 7}{3}$ Answer

In your own words, explain why C=2πr, where C is the circumference of a circle of radius r. Include a description of the number

schepotkina [342]

Answer:

Pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle's size, this ratio will always equal pi(3.1415).

There are two radii in one diameter. The formula for circumference is pi*d when using diameter which explains the two in front of the formula given by your teacher.
