What is 3/8 + b/3= 5/12
Final answer:
To solve the equation 3/8 + b/3 = 5/12 for b, we find a common denominator, combine the fractions, and then isolate and solve for b. The solution for b is 1/8.
Explanation:
The equation presented by the student is 3/8 + b/3 = 5/12. To solve for b, we must first get a common denominator for the fractions to combine them. In this case, the common denominator is 24, since it is the least common multiple of 8 and 3. Multiplying each term by 24 yields:
(3/8)*24 + (b/3)*24 = (5/12)*24
9 + 8b = 10
Next, we isolate the variable b by subtracting 9 from both sides of the equation:
8b = 10 - 9
8b = 1
Finally, divide both sides by 8 to solve for b:
b = 1/8
Thus, the value of b that satisfies the given equation is 1/8.
A dog takes 3 steps to walk the same distance for which a cat takes 4 steps. If 1 step of the dog covers 1/2 door how many feet will the cat cover on 24 steps?
Answer:
9 feet will the cat cover on 24 steps.
Step-by-step explanation:
Given: A dog takes 3 steps to walk the same distance for which a cat takes 4 steps.
⇒ 3 steps of dog=4 steps of Cat
If 1 step of the dogs cover [tex]\frac{1}{2}[/tex] feet
then,
4 steps of cat=3 steps of dog
24 steps of cat=[tex]\frac{3}{4}\times(24)[/tex]=18 steps of dog
Also, 1 step of the dogs cover=[tex]\frac{1}{2}[/tex] feet
18 steps of the dogs cover=9 feet
therefore, 24 steps of cat will cover 9 feet .
finding terms of an arithmetic sequence with a recursive formula

Hey there!!
Recursive formula :
... a( n ) = a ( n - 1 ) + 7
The first term is 12
To find the second term, we will need to substitute 2 in place of ' n '
2 term :
... a( 2 ) = a ( 2 - 1 ) + 7
... a( 2 ) = a( 1 ) + 7
We know a( 1 ) = 12
... a( 2 ) = 12 + 7
... 19 is the second term and we will need to use this to find the other terms.

A roller coaster car rapidly picks up speed as it rolls doen a slope. As it starts down the slope, it's speed is 4m/s. But 3 seconds later, at the bottom of the slope, it's speed is 22m/s. What is its average acceleration?
The average is 18m/s.
The average acceleration of the roller coaster car is [tex]\( 6\, \text{m/s}^2 \)[/tex].
The average acceleration of the roller coaster car is calculated using the formula:
[tex]\[ a = \frac{{v_f - v_i}}{{\Delta t}} \][/tex]
where [tex]\( v_f \)[/tex] is the final velocity, [tex]\( v_i \)[/tex] is the initial velocity, and [tex]\( \Delta t \)[/tex] is the time interval over which the acceleration occurs.
Given:
[tex]- Initial velocity (\( v_i \)) = 4 m/s \\- Final velocity (\( v_f \)) = 22 m/s\\ - Time interval (\( \Delta t \)) = 3 s[/tex]
Plugging in the values:
[tex]\[ a = \frac{{22\, \text{m/s} - 4\, \text{m/s}}}{{3\, \text{s}}} \] \[ a = \frac{{18\, \text{m/s}}}{{3\, \text{s}}} \] \[ a = 6\, \text{m/s}^2 \][/tex]

A) 29 with a remainder of 4
B) 207 with a remainder of 4
C) 209
D) 209 with a remainder of 4
D) 209 with a remainder of 4
The question is about the division of 1467 by 7. The answer is '209 with a remainder of 4'.
Explanation:This question is about division in mathematics. To solve this, we will divide 1467 by 7. Division is really repeated subtraction. You subtract 7 from 1467 as many times as you can until you get a number smaller than 7. That number is called the 'remainder', and the number of times you could subtract is the 'result' of the division.
After the division, the quotient is 209 and the remainder is 4. Therefore, the correct option is 'D) 209 with a remainder of 4'.

A total value of $6,000 is invested into two simple interest accounts. The annual simple interest rate on one account is 9%; on the second account, the annual simple interest rate is 6%. How much should be invested in each account so that both accounts earn the same amount of annual interest.
hello there this one was tricky i looked at it for sevrel minutes and solve dit
the answer is 50%
To obtain the same annual interest on both accounts, $3,600 should be invested at 9%, and $2,400 should be invested at 6%.
Explanation:To solve this problem, we need to use the formula for simple interest, which is I = PRT, where P is the principal amount (the initial amount of money), R is the annual interest rate in decimal form, and T is the time the money is invested for in years. Here, we want both accounts to earn the same annual interest, so we'll let x be the amount of money invested at 9%, and 6000 - x be the amount of money invested at 6%. The annual interest for both should be the same, so:
x × 0.09 = (6000 - x) × 0.06
Solving for x, we get x = $3,600. So, $3,600 should be invested at 9%, and $2,400 ($6,000 - $3,600) should be invested at 6% to obtain the same annual interest.

Solution:
Work:
To solve the given system of equations by substitution, 'y' from the first equation is substituted into the second, resulting in x = 4/3. Substituting this into the first equation yields y = 5/3. Therefore, the solution to the system is x = 4/3, y = 5/3.
Explanation:To solve the given system of equations by substitution, we will start with the first equation y = 2x - 1 and substitute it into the second equation 6x - 3y = 7.
Substituting 'y' from the first equation into the second, we get: 6x - 3(2x - 1) = 7.
Solving this, we find 'x': 6x - 6x + 3 = 7 => x = 7/3 = 4/3.
Next, we substitute 'x' into the first equation to find 'y': y = 2(4/3) - 1 = 8/3 - 1 = 5/3.
So, the solution to the system of equations is x = 4/3, y = 5/3.

What is 12x - 5 = 127
Here is your equation:
[tex]12x-5=127[/tex]
You're trying to find x, and to do that, the variable must be alone. That means you need to cancel out everything with it. The only thing with the variable 12x is -5. To cancel that out, you have to do the opposite of it, which is +5. Add 5 to both sides.
[tex]12x-5+5=127+5 \\12x=132[/tex]
12x(12 times x) is equal to 132. You need to find x. You have to do the opposite of times 12, which is divide by 12. Divide both sides by 12.
[tex]\frac{12x}{12} = \frac{132}{12} \\ \\x=11[/tex]
Your answer is x is equal to 11 ; x = 11

examine the diagram on the right and explain how it illustrates the value of n^+n/2
the key is to write [tex]n^2 + n[/tex] as [tex]n(n+1)[/tex] which can be easily seen as an area of a rectangle with one side length n and the other (n+1). That explains the rectangle made of dots - 3 x 4
Now you only have half of them because of the 1/2. So that explains the lower "triangle" of dots being greyed out - they do not count in the area (upper triangle). So the count of the dark dots corresponds to the original expression.
For n=5 you can draw a similar rectangular matrix with 5 x 6 dots. And count only the upper triangular part.
Name two points on a line that has a slope of 5/8
The two points on a line such that it has a slope 5/8 is:
(0,0) and (8,5)
Step-by-step explanation:We know that the slope of a line is the ratio of the change in the y-coordinates to the change in the x-coordinates.
Now, let us assume that the equation of a line with slope 5/8 be given by:
[tex]y=\dfrac{5}{8}x[/tex]
Hence, the point (0,0) lie on the line.
( since, when x=0 we have:
[tex]y=\dfrac{5}{8}\times 0\\\\y=0[/tex] )
and also the point (8,5) lie on the line.
( when x=8 we have:
[tex]y=\dfrac{5}{8}\times 8\\\\y=5[/tex] )

Applying the concept of Algebra, the toll collector processed 40 cars and 5 buses during a 4-hour period. This is found by checking each option against the equations 8c + 9b = 368 and c + b = total number of vehicles (where c = cars and b = buses).
Explanation:To solve this problem, we need to find the number of cars and buses that make up the total toll collected, which is $368. We can set up a system of equations to solve for the two variables: number of cars (c) and number of buses (b).
So, we have two equations: 8c + 9b = 368 and c + b = total number of vehicles. By checking each option, only 40 cars and 5 buses match these equations, because 8*40 + 9*5 = 368.
So, the toll collector processed 40 cars and 5 buses during the 4 hour period.

Is (2,10) a solution of the equation y = 9x
This line is already in slope-intercept form.
The slope of the line is 9, and the y-intercept is 0.
Because of this, we can find every y value for any x value simply by replacing x with the value of the x coordinate.
By replacing x with 2, we can see what the y coordinate would be when x is 2.
9(2) = 18
The y value would be 18, which is not 10, meaning (2, 10) is not a solution to the equation.
The point (2,10) is not a solution to the equation y = 9x because when x is substituted into the equation, it results in y = 18, not y = 10 as in the point.
To determine if the point (2,10) is a solution to the equation y = 9x, we need to substitute the x-value from the point into the equation and see if the corresponding y-value matches the one in the point. Let's substitute x = 2 into the equation:
y = 9 x 2
y = 18
For the point (2,10), the y-value is 10, which does not equal the calculated y-value of 18. Therefore, the point (2,10) is not a solution to the equation y = 9x.

Now the value of z will be,
→ 9z + 10 = 1 - 3(5 - 3z)
→ 9z + 10 - 1 = -15 + 9z
→ 9z + 9 = -15 + 9z
→ 9z - 9z = -15 - 9
→ 0 = -24
→ [ z = no solution ]
Hence, there is no solution.
