Answer:

18

Step-by-step explanation:

18 can be divided by 18 =1

54 divided by 18 = 3

The greatest common factor of numbers 18 and 54 is,

⇒ GCD = 18

The highest number that divides exactly into two more numbers, is called  Greatest common factors.

We have to given that;

To find the greatest common factor of 18 and 54.

Now, We know that;

Greatest common factor of numbers are that highest number which divides exactly into two more numbers,  

Here, The numbers are,

⇒ 18 , 54

⇒ 18 = 18

⇒ 54 = 18 × 3

Hence, The greatest common factor of numbers 18 and 54 is,

⇒ GCD = 18

Answer:

FV= $819.03

Step-by-step explanation:

Giving the following information:

Initial investment= $600

Number of periods= 5*12= 60 months

Interest rate= 0.062/12= 0.0052

To calculate the future value of the investment, we need to use the following formula:

FV= PV*(1+i)^n

FV= 600*(1.0052^60)

FV= $819.03

Answer: 3c - 5

Step-by-step explanation:

Since c represent the number of cookies that Mark made. We are then informed that Peter made five less than triple as many cookies as Mark. This will be:

= (3 × c) - 5

= 3c - 5

The expression is 3c - 5

Answer:

The solutions to the quadratic equations will be:

[tex]x=\sqrt{57}+6,\:x=-\sqrt{57}+6[/tex]

Step-by-step explanation:

Given the expression

[tex]x^2-12x\:=\:21[/tex]

Let us solve the equation by completing the square

[tex]x^2-12x\:=\:21[/tex]

Add (-6)² to both sides

[tex]x^2-12x+\left(-6\right)^2=21+\left(-6\right)^2[/tex]

simplify

[tex]x^2-12x+\left(-6\right)^2=57[/tex]

Apply perfect square formula: (a-b)² = a²-2ab+b²

i.e.

[tex]x^2-12x+\left(-6\right)^2=\left(x-6\right)^2[/tex]

so the expression becomes

[tex]\left(x-6\right)^2=57[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

solve

[tex]x-6=\sqrt{57}[/tex]

add 6 to both sides

[tex]x-6+6=\sqrt{57}+6[/tex]

Simplify

[tex]x=\sqrt{57}+6[/tex]

also solving

[tex]x-6=-\sqrt{57}[/tex]

add 6 to both sides

[tex]x-6+6=-\sqrt{57}+6[/tex]

Simplify

[tex]x=-\sqrt{57}+6[/tex]

Therefore, the solutions to the quadratic equation will be:

[tex]x=\sqrt{57}+6,\:x=-\sqrt{57}+6[/tex]

Answer:

Let the required angles be 7x and 11x

According to the above problem,

[tex]7x + 11x + 90 = 180 \\ 18x = 90 \\ \boxed{ x = 5}[/tex]

★1st angle= 7x= 35°

★2nd angle=11x= 55°

★3rd angle is 90°

2. 35°,55°,90° is the right answer.

Answer:

x = 400

Step-by-step explanation:

5x + 100 = 2100

5x = 2000 (subtarct 100 from both sides)

x = 400 (Divide 5 from both sides)

x = 400

Answer:

x=400

5x+100=2100

5x=2100-100

5x=2000

x=400

Answer:

The interest is $1350 and the amount is $5850.

Step-by-step explanation:

STEP 1: Find an interest by using the formula I = P*I*T, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this example P = $4500, i = 7.5% and t = 4 years, so

4500*0.075*4

I = 1350

STEP 2: Find an amount by using the formula .

Since P = $4500 and I = $1350 we have

$4500 + $1350 = $5850

Given

Shape: Rhombus

[tex]JL = 48[/tex]

[tex]KM = 20[/tex]

Required

Determine the perimeter

The given parameter are the diagonals of the rhombus.

The perimeter (from diagonals) is calculated as thus:

[tex]P = 2\sqrt{(JL)^2 + (KM)^2}[/tex]

Substitute values for JL and KM

[tex]P = 2\sqrt{48^2 + 20^2}[/tex]

[tex]P = 2\sqrt{2304 +400}[/tex]

[tex]P = 2\sqrt{2704}[/tex]

[tex]P = 2 * 52[/tex]

[tex]P = 104[/tex]

Hence, the perimeter is 104 units

Step-by-step explanation:  What is the value of the x-coordinate of the point of ... We can solve the system of equations by substituting the value of y from the second equation into the first. y = 2x + ... Thus, the second and third lines intersect at (-11/2,-8). ... 6y - 3x = -6: 4x - 5y + (6y - 3x) = 12 + (-6). 4x - 3x + 6y - 5y = 12 - 6. x + y = 6.
