Samir buys x cans of soda at 30 cents each and (x+4) cans of soda at 35 cents each. The total cost was $3.35. Find x
Answers
An equation is formed of two equal expressions. The value of x is 3.23.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The cost of x cans can be written as
The cost of (x+4) cans can be written as,
Now, the total cost of the cans is given to us like $3.35, therefore, the value of x can be written as,
Hence, the value of x is 3.23.

Cost of Soda A + Cost of Soda B = Total Cost
0.30x + 0.35(x+4)=3.35 --> Expand 0.35(x+4)
0.30x + 0.35x + 1.4 = 3.35 --> Add the x's and subtract 1.4
0.65x = 1.95 --> Divide by 0.65
x = 3
Samir buys 3 cans of soda at 30 cents each and 7 (3+4) cans of soda at 35 cents each. Samir buys a total of 10 cans of soda.

Answer: The contrapositive of the statement is
"If a number is not divisible by 10, then it does not end with 0".
Step-by-step explanation: We are given to write the contrapositive of the following statement:
"If a number ends with 0, then it is divisible by 10".
We know the contrapositive of a conditional statement of the form
"If p then q" is given by "If not q then not p".
Or,
the contrapositive of "p ⇒ q" is "~q ⇒ ~p".
So, the contrapositive of the given statement is
"If a number is not divisible by 10, then it does not end with 0".
Thus, the contrapositive of the statement is
"If a number is not divisible by 10, then it does not end with 0".
So the contrapositive for this statement would be, "If a number is NOT divisible by 10, then it does NOT end with 0". ("not" capitalized for emphasis)

The required simplified value of the given expression at x = -4 and y = 4 is 16, 385/4. Option D is correct.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
when x = -4 and y = 4.
Expression = x⁶ - x/4y
Put x = -4 and y = 4.
= (-4)⁶ - [-4 /(4×4)]
= 4096 + 1/4
= 16385/4
Thus, the required simplified value of the given expression at x = -4 and y = 4 is 16, 385/4. Option D is correct.

Final answer:
After evaluating the expression x^6 - x/4y with the given x = -4 and y = 4, the answer comes out to be 4096.25, which is not currently listed in the provided options. A likely explanation for this could be a typo or error in the question.
Explanation:
The given expression is: x^6 - x/4y . Now, let's substitute the given values x = -4 and y = 4 into the expression.
Therefore, (-4)^6 - (-4/4*4) = 4096 - (-4/16)
This gives 4096 - (-1/4) or 4096 + 1/4.
That simplifies to 16384/4 + 1/4 = 4096.25 which is none of the options presented. Hence, the correct answer should be "4096.25."

In this question, we're trying to find how much money she'll have after 18 visits.
We know that she already paid $393 dollars
We also know that there is a $5 deduction from the account for every time she uses the club
x = visits to the club
y = value remaining in the account
Our equation would be:
y = -5x +393
Since we know that she visited the club 18 times, plug 18 into x and solve:
y = -5(18)
y = -90 + 393
y = 303
This means that after 18 visits, there will be a remaining balance of $303
Answer:
$303
Answer:
y= 393- 5(x) after 18 visits value remaining in her account is 303$
Step-by-step explanation:
let the amount in her account be y $
y= 393- 5(x) where x is the number of visits.
after 18 visits y= 393- 5(18)= 393-90= $303
