solve the equation 243×=73, where × is the base of the number.
The value of × that satisfies the equation 243× = 73 is approximately 0.6691.
To solve the equation 243× = 73, where × represents the base of the number, we need to determine the value of × that satisfies the equation.
We can start by rewriting the equation as an exponential equation:
243ˣ= 73
To solve for ×, we need to isolate × on one side of the equation. We can do this by taking the logarithm of both sides of the equation. Let's take the logarithm with base 10 (log) for simplicity:
log(243ˣ) = log(73)
Applying the logarithmic property, we can bring down the exponent × as a multiplier:
× * log(243) = log(73)
Now, we can solve for × by dividing both sides of the equation by log(243):
× = log(73) / log(243)
× ≈ 0.6691
Therefore, the value of × that satisfies the equation 243× = 73 is approximately 0.6691.

Group of answer choices
800
8700
870
87
Answer:
870 as it is the only number in the list which closest and lesser then 956.
(if you divide, then you get 10 as quotient and 86 as remainder)
we can also take 87 but the question mentions with multiples of 10.

0 1 2 3 4 5 is an example of what set
Step-by-step explanation:
A set which is not finite is called an infinite set. Example: A set of all whole numbers. A = {0,1,2,3,4,5,6,7,8,9……}2x + 2y = –2 and 3x – 2y = 12 what does x and y equal?
Answer:
(2,-3)
Step-by-step explanation:
by elemination
2x + 2y = –2
3x – 2y = 12
cross out the 2y and -2y because the cancle each other.
that leaves 2x= -2
and 3x = 12.
simply add/subtract. 2x+3x=5x
-2+12=10.
5x=10
x=2.
now for the y. we have x so all we have to do is plug.
take any equation. 2x + 2y = –2 and plug 2 into the x.
2(2)+ 2y = –2
4+2y= -2
-2-4= -6
2y=-6
y=-3.
put x and y into ordered pairs
(2,-3) and done.
easy peasy.
Answer:
x=2 y= -3
Step-by-step explanation:
2x+2y = -2
x+y = -1 (dividing both sides with 2
x+1 = -y
3x - 2y = 12
3x + (-y)(2) = 12
3x + (x+1)(2) = 12
3x+2x+2=12
5x+2=12
x=2
-y= 1+2
y= -3
Which expression shows the quotient of two terms where one of the terms includes the coefficient of 8?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete; So, I will solve generally
Required
Quotient of two terms where 1 has a coefficient of 8
The quotient (Q) of a and b can be represented as:
[tex]Q = \frac{a}{b}[/tex]
Where a and b are the terms
For a or b to have a coefficient of 8, then a or b must be
[tex]a\ or\ b = 8x[/tex]
Where x is the variable
So, the quotient can be expressed as any of:
[tex]Q = \frac{8x}{y}[/tex]
[tex]Q = \frac{z}{8i}[/tex]
[tex]Q = \frac{24b}{8c}[/tex]
As long as one of the terms has a coefficient of 8
Anya rolls an octahedron labelled A A A B C C C C what is the probability the octahedron will land on each letter
Answer:
the probability the octahedron will land on A is 3/8
the probability the octahedron will land on B is 1/8
the probability the octahedron will land on C is 4/8 or 1/2
Step by Step explanation:
All u have to do to figure this out is to first count the total amount of letters and in this case there are 8. To find the probability of a specific letter, you have to count how many of that letter there is in the total of 8. For example the letter A's probability is 3/8 since there are 3 A's and 8 letters in total.

Answer:
.01*.5ˣ
Step-by-step explanation:
we can see that x=0 y= .01
so in our equation
a*bˣ
a=.01
This is throuhg plugging in 0 for x
a*b⁰=.01
a*1=.01
a=.01
Now it's just a matter of finding b
to do this just plug in a value
we know that when x=1 y=.005
.01*b¹=.005
b= .5
So our final equation is : .01*.5ˣ

A ) 8 times
Explanation:
There are two 1's shown on the spinner out of 6 numbers. The probablility of rolling a 1 is 2/6 or 1/3.
If you spin the spinner 24 times, you need to multiply the probablility by 24 or 1/3 x 24, which is 8.
