5+2x /3x -1= 6/7 find the answer.
Answers
To solve the equation 5 + (2x / 3x) - 1 = 6/7, we can follow these steps: Step 1: Simplify the expression on the left side of the equation. The expression (2x / 3x) can be simplified to 2/3 by canceling out the common factor of x. So, the equation becomes 5 + (2/3) - 1 = 6/7. Step 2: Combine like terms on the left side of the equation. The expression 5 + (2/3) - 1 can be simplified to (15/3) + (2/3) - (3/3) = 14/3. So, the equation becomes 14/3 = 6/7. Step 3: Cross-multiply to eliminate fractions. Multiply the numerator of the left side (14) by the denominator of the right side (7), and multiply the denominator of the left side (3) by the numerator of the right side (6). This gives us: 14 * 7 = 3 * 6. Step 4: Simplify and solve for x. Simplifying the equation gives us 98 = 18. Since 98 is not equal to 18, the equation is not true. Therefore, there is no solution for the given equation. In conclusion, the equation 5 + (2x / 3x) - 1 = 6/7 does not have a solution.
= 7 1/4
Step-by-step explanation:
If the question is written this way,
5 + 2x / 3x - 1 = 6/7
Cross multiply by both sides
7 (5 + 2x) = 6 (3x - 1)
35 + 14x = 18x - 6
Group liked terms
35 + 6 + (14x - 14x) = 18x - 14x +(6 - 6)
41 = 4x
Divide both side by 4
41/4 = 4x/4
41/4 = x
: . x = 10 1/4
Thank you

The price of senior citizen ticket is 8 and price of student ticket is 14.
What is Equation?
Two or more expressions with an Equal sign is called as Equation.
Let x be the price of senior citizen ticket
y be the price of student ticket.
On the first day of ticket sales the school sold 4 senior citizen tickets and 5 student tickets for a total of $102.
4x+5y=102..(1)
The school took in $126 on the second day by selling 7 senior citizen tickets and 5 studenttickets.
7x+5y=126..(2)
Subtract equation 1 and 2
4x+5y-7x-5y=102-126
-3x=-24
Divide both sides by 3
x=8
Now let us find y
4(8)+5y=102
32+5y=102
Subtract 32 from both sides
5y=102-32
5y=70
y=14
Hence, the price of senior citizen ticket is 8 and price of student ticket is 14.

x = cost of senior citizen ticket
y = cost of student ticket
4x + 5y = 102
7x + 5y = 126
4x + 5y = 102
4x = 102 - 5y
x = (102 - 5y)/4
x = 102/4 - 5y/4
7x + 5y = 126
7(102/4 - 5y/4) + 5y = 126
(714/4 - 35y/4) + 5y = 126
-35y/4 + 5y = 126 - 714/4
note:
-35y/4 = -8.75y
714/4 = 178.5
-8.75y + 5y = 126 - 178.5
-3.75y = -52.5
y = -52.5/-3.75
y = 14
x = 102/4 - 5y/4
x = 102/4 - 5(14)/4
x = 8
x = cost of senior citizen ticket = $8/ea
y = cost of student ticket = $14/ea

Answer: a.
Step-by-step explanation:
We know that the volume of a cylinder is given by :-
, where r is radius and h is height of the cylinder.
Given: The diameter of cylinder = 40 mm
The radius of cylinder =
The height of cylinder = 30 mm
Then , the volume of the cylinder will be :-
Hence, the volume of the cylinder =
= (pi/4)*D^2 * h
= (pi/4)*(40)^2 * 30
= 37,680 mm3

Answer:
#2 is not a function
Step-by-step explanation:
Although there can be multiple y-values attributed to a single x-value, there can only be ONE x-value(of a number) in a function, so #2 would be incorrect seeing as it uses the x-value, 2, two times.
