Well, I believe the answer is b. But technically, it would depend on the size of the ice cube.

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!

Answer:

Kid tickets = $4

Adult tickets = $7

Step-by-step explanation:

3K+9A=75 this is the equation for this week, it shows how many adult and kid tickets were added up to a total of $75

8K+5A=67 this is the equation for last week, it shows how many adult and kid tickets were added up to a total of $67

here, we can use substitution or elimination with these two formulas:

3K+9A=75

8K+5A=67

Substitution method; solve one equation for a variable and use the value in the other equation, such as follows:

3K+9A=75 we will solve for the variable, K, seeing that both 9 and 75 are divisible by K's coefficient of 3

3K+9A=75 subtract 9A from both sides to get 3K=75-9A

3K=75-9A divide by 3 to get K by itself, leaving us with K=25-3A

now that we know K=25-3A, we can substitute it's new value in the other equation: 8K+5A=67

8(25-3A)+5A=67 we will multiply out to get rid of the parentheses first because of PEMDAS

200-24A+54=67 now we add like terms to simplify to 200-19A=67

now we subtract 200 from both sides to get -19A=-133

now we divide by -19 to get A by itself A=7

Now that we have A, we can plug it into any equation to get K

let's use the first equation: 3K+9A=75

3K+9(7)=75 this simplifies to 3K+63=75 and then 3K=12 we divide by 3 to get K=4

With this information, we know now that each Kid ticket cost $4 and each adult ticket cost $7

Now, if we were to use elimination, it would look like this because we eliminate one variable like I do here:

our Greatest Common Factor (GCF) is 24 between the Ks

3K+9A=75 we can multiply this whole equation by 8

8K+5A=67 and this equation by -3

8(3K+9A=75)   =   24K+72A=600

-3(8K+5A=67)  =  -24K-15A=-201

if we set this up like subtraction, we can eliminate K because 24 is cancelled out by -24 and we are left with this:

72A=600

-15A=-201

we add the equations to get this:

57A=399 and now we divide to get A

A=7

Again, now that we have A, we use it in an equation, just like in Substitution. This time I will demonstrate with the second equation: 8K+5A=67

8K+5(7)=67 ypu should know the steps by now, so I am going to skip to the last step:

8K=32 K=4

Hope that helps!

Answer:

I hope this is what you mean, it could be 238, 328, 823, 283, 832, and many more.

Answer:

The equation of line perpendicular to given line and passes through points  ( - 1 , 4 ) is 2y = -3x + 5

Step-by-step explanation:

Given line equation as :

3 y = 2 x - 1

Or, y = x -  

So ,  The equation is in the form of y = m x + c

Where m is the slope of the line

∴ satisfying the condition

Slope of given line is  m =

Now , ∵ The other line is perpendicular to this line and passes through point    ( - 1 , 4 )

Let , Slope of other line  = M  

∴ for perpendicular line condition , products of the slope = - 1

I.e m × M = - 1

Or , M = -

Or   M = -

Or   M =  -

Thus The equation of line with slope M and passing through points  ( - 1 , 4 ) is

or,   (x + 1)[/tex]

or, 2y - 8 = - 3 (x +1)

Or, 2y - 8 = - 3x - 3

or   2y = - 3x - 3 + 8

∴   2y = -3x + 5

Hence The equation of line perpendicular to given line and passes through points  ( - 1 , 4 ) is 2y = -3x + 5  Answer
