The expression 6a − 3b = 5b after solving for a:b is 4:3 after using arithmetic operation.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that:

The expression is:

6a − 3b = 5b

To solve the above expression:

6a = 5b + 3b

6a = 8b

a/b = 8/6

As we know,

The expression can be defined as the combination of constants and variables with mathematical operators.

a:b = 8: 6

a:b = 4: 3

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variabe.

Thus, the expression 6a − 3b = 5b after solving for a:b is 4:3 after using arithmetic operation.

let y = x^2

4y^2 -21y + 20 = 0

solve for y

then substitute back in to get x

Answer:

4y^2 - 21y + 20 = 0

Step-by-step explanation:

As (4x^4 - 21x^2 + 20=0) being a biquadratic equation, meaning it is a 4-degree equation without the terms of degree 1 and 3.

To solve this particular case you only need to replace the variables of degree 4 and 2 for a new variable of degree 2 and 1 and solve it as regular quadratic equation and then undo the change.

* Using a new variable we can rewrite the equation:

Let y be the new variable;

y= x^2, then y^2= x^4

Then we have;

4y^2- 21y+20=0

Solve for y and then find X which will be the roots for the biquadratic equation.

We have

k^2 - 25f^2 + 5kf - 25f^2 =

k^2 - (5f)^2 + 5f( k - 5f) =

( k - 5f )( k + 5f ) + 5f( k - 5f ) =

( k - 5f )( k + 5f + 5f ) =

( k - 5f )( k + 10f );

Step-by-step explanation:

Answer:  The required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]

Step-by-step explanation:  We are given to factor the following quadratic expression :

[tex]E=k^2+5kf-50f^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To factor the given expression, we need two integers with sum 5 and product -50 and those two integers are 10 and -5.

The factorization of expression (i) is as follows :

[tex]E\\\\=k^2+5kf-50f^2\\\\=k^2+10kf-5kf-50f^2\\\\=k(k+10f)-5f(k+10f)\\\\=(k-5f)(k+10f).[/tex]

Thus, the required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]

Because there are 2 minus signs next to each other, we can replace both of them with a single plus sign.

Simplify 1/3x to x/3

y = -x/3 - 9

Add 9 to both sides

y + 9 = -x/3

Multiply both sides by 3

(y + 9) * = -x

Regroup terms

3(y + 9) = -x

Using the formula, rewrite in standard form

Answer: x + 3y = -27

To convert the equation y = -1/3x - 9 to standard form, you need to eliminate the fraction and rearrange the equation. Multiply both sides of the equation by 3 to get 3y = -x - 27. Rearrange the equation to get x + 3y = -27, which is the standard form.

The equation y = -1/3x - 9 can be written in standard form as Ax + By = C, where A, B, and C are constants. To write the equation in standard form, we need to eliminate the fraction by multiplying both sides of the equation by 3. This gives us 3y = -x - 27. Rearranging the equation, we get x + 3y = -27, which is the standard form.

Jayden's stack of superhero cards, which is 0.41 meters high, is taller than Brett's stack of superhero cards, which is 0.405 meters high. The number sentence to compare them is 0.41 > 0.405.

The student is asking to write a number sentence that compares Jayden's stack of cards to Brett's stack of cards.

Jayden's stack was 0.41 meter high, and Brett's stack was 0.405 meter high. To compare these two stacks, we look at the decimal values given for the heights. Since 0.41 is greater than 0.405, the number sentence that compares the two stacks is:

Jayden's stack > Brett's stack

Or in terms of the specific values:

0.41 > 0.405

This shows that Jayden's stack of cards is taller than Brett's stack of cards.

Maya swims 0.75 kilometers each day because to convert 750 meters to kilometers, we divide by 1,000.

The student wishes to know how many kilometers Maya swims each day if she swims 750 meters. To convert meters to kilometers, we use the fact that 1 kilometer is equivalent to 1,000 meters. So, to find out how many kilometers 750 meters is, we divide the number of meters by 1,000.

750 meters \/ 1,000 = 0.75 kilometers

Therefore, Maya swims 0.75 kilometers each day.

You can use the given distance to amount of gasoline used relationship to find how much gasoline is needed for 1 km of traveling. Then use that data to find the amount of gasoline needed to travel 500 km.

The amount of gasoline needed to travel 500 km is 40 L

We can equate the 150 km figure to 12 L use of gasoline on the basis of usage.

Thus,

[tex]\rm 150 \: km = 12 \: L\\\\\\\text{Dividing both quantities in 150 parts}\\\\\\dfrac{150}{150} \: km = \dfrac{12}{150} \: L\\\\1 \: km = 0.08 \: L[/tex]

Thus, there will be use of 0.08 L gasoline for travelling 1 km by that same car.

Using that above derived relationship, we can find the amount of gasoline needed to travel 500 km by that same car.

[tex]1 \rm \: km = 0.08 \: L\\\\\text{Multiplying 500 on both the sides}\\\\500 \: km = 40 \: L[/tex]

Thus,

The amount of gasoline needed to travel 500 km is 40 L

Answer: The answer to this problem is: no solution

Step-by-step explanation: The trick to solving this problem is listing out 38's factors:

1, 2, 19, 38. As you can see, none of these pairs add up to 15, so there is no solution (unless you are talking about fraction factors)

The equation is: 7 + (x + 5)

The expression for '7 plus the sum of a number x and 5' is written as '7 + (x + 5)'.

The phrase '7 plus the sum of a number x and 5' can be written as an algebraic expression. This involves taking the sum of the variable x and the number 5, and then adding 7 to this sum. In mathematical terms, this is expressed as 7 + (x + 5).

Let's break it down step by step:

First, identify the sum: x + 5.

Next, add 7 to the result of this sum.

So, if we were to evaluate this expression for x = 4, we would calculate it as follows:

7 + (4 + 5) = 7 + 9 = 16

1 ≤ s -8

1+8 ≤ s

1 ≤ s - 8

Simplify the inequality, then the value of the variable s will be

1 ≤ s - 8

1 + 8 ≤ s

9 ≤ s

Thus, the value of the variable s is greater than or equal to 9.

x-scale is a time in hours

and we are given

The graph of the distance a car travels at a constant speed passes through the points (0,0) and (2,136)

so, points would be

(0,0)

x1=0 , y2=0

(2,136)

x2=2 , y2=136

so, slope would be speed

because speed = distance / time

we can use slope formula
