Simplest form for 4/15X18

Step-by-step explanation:

let the num be 3x & 4x

3x+4x=28

7x=28

x=28/7

x=4

now, num of girls=3x=3×4=12

& num of boys=4x=4×4=16

Answer: 12 girls

Step-by-step explanation: You first want to make this equation become a fraction with the number of girls on top and the total on bottom. This becomes 3/7. To make this over 28, multiply by 4 on the top and the bottom. This makes 12/28, making 12 girls the answer.

The greatest common factor (GCF) of 150, 275, and 420 is 25. It is the highest number that can divide all three numbers without a remainder and is found by identifying the common prime factors among them.

The question is asking for the greatest common factor (GCF) of the numbers 150, 275, and 420. The GCF is the highest number that can divide all three numbers without leaving a remainder. To find the GCF, we can break down each number into its prime factors:

the common factors for 150, 275, and 420 are 5 × 5, since these are the only prime factors that appear in all three prime factorizations. Consequently, the GCF of 150, 275, and 420 is 5 × 5, which equals 25.

Answer:

f(a + 2)= (5 + a) / (a - 1) or f(a+2)= (a+5)/(a-1)

Step-by-step explanation:

f(x)=(3+x)/(x-3)

To evaluate f(a+2), simply replace the x with a+2

f(a+2) = (3 + a+2)/(a+2 - 3)= (a+5)/(a-1)

or

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function:

f(a + 2) = (3 + a + 2) / (a + 2 - 3)

Simplifying the function generated above:

f(a + 2) = (5 + a) / (a - 1)

Step-by-step explanation:

f(x) = 3+x/x-3

Substituting x = a+2, we get

[tex]f(a + 2) = \frac{3 + (a + 2)}{(a + 2) - 3} \\ f(a + 2) = \frac{a + 5}{a - 1} [/tex]

which is the final answer.

The question is about solving an inequality, but the actual inequality is not fully provided. General steps have been given to approach solving such problems, with a note that a specific solution requires the complete inequality. The student should provide the full inequality for a precise solution.

The student is asking for help with solving an inequality problem. Without a complete and clear inequality provided, we are unable to give a full step-by-step solution. However, I can provide a general approach to solving linear inequalities:

If the student provides the full inequality, using these steps will lead to the solution, where you would then graph the solution set on a number line and use either parenthesis or brackets to denote whether endpoints are included (for 'greater/less than or equal to') or excluded (for 'greater/less than').

Answer:

203.5 N

Step-by-step explanation:

Force = mass × acceleration

F = ma

F = (55 kg) (3.7 N/kg)

F = 203.5 N

The weight of the Kai on planet mars is 203.5 N.

Weight can be defined as the heaviness of a person. Also, weight is the product of the mass of the object and the acceleration due to gravity (or gravitational field strength).

[tex]\rm{ Weight = mass \times gravitational\ field\ strength[/tex]

[tex]\rm{Kai's\ weight\ on\ Mars = Kai's\ mass \times gravitational\ field\ strength\ on\ Mars[/tex]

Answer: Find the lowest common denominator of the 2 denominators

Step-by-step explanation:

The common in both denominator is 15.

3: 3,6,9,12,15,18,21,24,27,30

5: 5,10,15,20,25.30,35,40,43,50

Since 5x3 is 15, 1/5 x 3/3= 3/15

Since 3x5 is 15, 2/3 x 5/5= 10/15

3/15 is equivalent to 1/5 and 10/15 is equivalent to 2/3.

3/15 + 10/15 is equal to 13/15

13/15 can't be simplified because they are both odd numbers and they have less than 2 factors.

Hope this helped! Have a nice day! :D  

Final answer:

To add 1/5 and 2/3, you must find the LCD, which is 15, convert the fractions to have the same denominators, then add them to get the sum of 13/15.

Explanation:

To add the unlike fractions 1/5 and 2/3, we first need to convert them to equivalent like fractions using their Least Common Denominator (LCD).

Prime factorize the denominators: 5 is already a prime number, and 3 is also a prime number.

To find the LCD, we take the product of the different prime factors, which is 5 × 3 = 15.

Convert each fraction by multiplying by an appropriate form of '1' to get the same denominator: 1/5 = (1×3)/(5×3) = 3/15 and 2/3 = (2×5)/(3×5) = 10/15.

With like denominators, we can now add the fractions: 3/15 + 10/15 = 13/15.

The final answer, 13/15, is already in its simplest form and cannot be reduced further.

Answer:

infinite solutions

Step-by-step explanation:

Given

- 6(n - 8) = 4(12 - 5n) + 14n ← distribute parenthesis on both sides

- 6n + 48 = 48 - 20n + 14n, that is

- 6n + 48 = 48 - 6n ( add 6n to both sides )

48 = 48 ← True

This indicates that the equation is true for any value of n

Answer:

This is a very classical type of equation in which, the solution is basically any number and it is known as an "Identity". So it has infinite solutions

Step-by-step explanation:

-6(n-8) = 4(12-5n)+14n

-6n-6*(-8) = 4*12+4*(-5n) + 14n

-6n+48=48-20n+14n

-6n+48=48-6n

-6n+48=48-6n

-6n +6n + 48 -48 = 48 -48 - 6n + 6n

Answer:

Step-by-step explanation:

In the expression

[tex]0.90(2.25d+1.40t+6),[/tex]

d is the number of drinks Lindy orders;

t is the number of toppings Lindy orders.

If Lindy and her friends order 4 drinks and a medium pizza with 3 toppings, then d = 4 and t = 3. Find the value of the expression above when d = 4 and t = 3:

[tex]0.90(2.25\cdot 4+1.40\cdot 3+6)=0.90(9+4.20+6)=0.90\cdot 19.20=17.28[/tex]

So, Lindy and her friends will pay $17.28

Lindy's total cost for ordering 4 drinks and a pizza with 3 toppings amounts to $17.28, so the correct answer is Option A.

First, we substitute the given number of drinks and toppings into the expression, resulting in 0.90(2.25*4 + 1.40*3 + 6). That simplifies to 0.90(9 + 4.2 + 6), which further simplifies to 0.90(19.2). Finally, we multiply 0.90 by 19.2 to get the total cost, that is $17.28, which implies the correct answer is Option A.

Answer:

D

Step-by-step explanation:

Since the constructed line is a perpendicular bisector of the line AB, then

AC = BC ← substitute values

4x + 12 = 2x + 18 ( subtract 2x from both sides )

2x + 12 = 18 ( subtract 12 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Hence

AB = 2AC = 2(4x + 12) ← substitute x = 3

AB = 2(12 + 12) = 2 × 24 = 48 → D

6 percent

Step-by-step explanation:

if the 6 was in the tenths place (1 to the left) it would be 60%, however it is in the hundreds place therefore its value is 6%

Final answer:

To convert 0.06 to a percent, multiply it by 100 to get 6%.

Explanation:

To change 0.06 to a percent, you multiply it by 100. Doing this moves the decimal point two places to the right.

Here's the step-by-step calculation:

Start with the decimal: 0.06

Multiply by 100: 0.06 × 100 = 6

Answer:

x-2y-8=0

Step-by-step explanation:

The equation of line is given by the relation

y-y1=m(x-x1)

where m is the slope

now, given x1=-4 and y1=-6 and the slope is 1/2.

substitute into the equation to get

y+6=1/2(x+4)

multiplying through with the L.C.M

which is 2

2(y+6)=1/2×2(x+4)

2y+12=x+4

making x the subject

x= 2y+8 hence the equation of the line is x-2y-8 =0

Final answer:

The equation of the line that passes through the point (-4, -6) with a slope of 1/2 is y = 1/2x - 4.

Explanation:

To find the equation of a line that passes through the point (-4, -6) with a slope of 1/2, we use the point-slope form of a line's equation which is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. In this case, the point is (-4, -6) and the slope m is 1/2.

Plugging in the values, we get:

y - (-6) = (1/2)(x - (-4))

Simplify the equation:

y + 6 = 1/2x + 2

To get the equation in slope-intercept form y = mx + b, we do:

y = 1/2x + 2 - 6

y = 1/2x - 4

So the equation of the line is y = 1/2x - 4.
