Find the HCF of 18 and 12

Answer:

12x+2+6x=110(Exterior angle is equal to sum of two non adjacent angles)

18x=110-2

18x=108

x=108/18

x=6

Therefore the value of x is 6

Step-by-step explanation:

We need to simply like terms. Let's break this out into four different problems that are easy to solve, then we can put it all back together for the final answer.

There are four like terms in both the numerator (top) and denominator (bottom) of the fraction. Numbers, m, p, and v. We will look at each of these seperately.

What is [tex]45/15[/tex]? Easy right, just 3.

Let's move on to the harder parts.

[tex]\frac{m^{-6}}{m^{-2}}[/tex]

Remember that negavite exponents mean to divide.

For example, [tex]2^{-2} = \frac{1}{2^2} = 1/4[/tex]

So we just need to apply this rule to both of these exponents to get,

[tex]\frac{m^2}{m^6}[/tex]

Now remember that when dividing by exponents, the exponents subtract from each other[tex]\frac{x^y}{x^z} = x^{y-z}[/tex]

So we get, [tex]m^{2-6} = m^{-4} = \frac{1}{m^4}[/tex]

So far we have

[tex]\frac{3}{m^4}[/tex]

Keep applying the same rules for the other two terms. Reply back if you need more help and I can keep working through with you.

Answer: 48

Step-by-step explanation:

Here's the complete question:

The mean number of people per household in eight households is six people. what is the total number of people in the eight households?

First and foremost,we should note that mean means the average of a given set of numbers.

Since the mean number of people per household in eight households is six people, the total number of people in the eight households would be calculated by multiplying 6 by 8. This would be:

= 6 × 8

= 48 people

The question is incorrect

Type the correct answer in each box. Use numerals instead of words. Consider the quadratic equation -x² − 5x + 6 = 0.

Answer:

(−x + 1)(x + 6)

Step-by-step explanation:

-x² − 5x + 6

-x² - 6x + x + 6

(-x² - 6x) +(x +6)

= -x (x + 6) + 1(x +6)

=(−x + 1)(x + 6)

Answer:

Width of the garden box = 4 feet

Step-by-step explanation:

Given that:

Length of garden box = 22 feet

Let,

w be the width of garden box

It is also given that:

The length of a garden box is 6 feet longer than 4 times the width.

L = 4w + 6

Putting L = 22

22 = 4w + 6

22 - 6 = 4w

4w = 16

Dividing both sides by 4

[tex]\frac{4w}{4}=\frac{16}{4}\\w=4[/tex]

Hence,

Width of the garden box = 4 feet

Ryan calculated an estimation of 93*48= 4464

The percent error is [tex]|\frac{Actual- estimate}{actual} | = \frac{4700-4464}{4700} = \frac{236}{4700} = approx . 5.02 %, or C[/tex]%

Answer:

The value of sin X = 12 / 13

Step-by-step explanation:

Given

To determine

sin X = ?

We know that the trigonometric ratio involving sin Ф such as

sin Ф = opposite / hypotenuse

Here:

so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation

sin Ф = opposite / hypotenuse

sin X = 12 / 13

Therefore, the value of sin X = 12 / 13

Cost of renting a truck for one day = $96

Money Calvin can spend = $120

Money left with Calvin after he spends on the daily rent :

[tex] = \tt120 - 96[/tex]

[tex] = \tt\$ 24[/tex]

Cost charged per mile = 0.60

Number of miles he can drive the rental truck :

[tex] =\tt 24 \div 0.60[/tex]

[tex] = \color{plum}\tt40 \: \: miles[/tex]

Thus, number of miles he can run the truck = 40 miles

Therefore, Calvin can run the truck for 40 miles after he pays the daily fee.

Area of triangle= 1/2 (Length x breadth)

For first triangle : 1/2 x 6 x 2= 6cm^2

For the second triangle:

Answer:

A) {-1,2}

Step-by-step explanation:

square both side of the equation. Then:

x+2=x^2

simplify:

x^2-x-2=0

factor:

(x+1)(x-2)=0

then:

x=-1, x=2

Answer:

B

Step-by-step explanation:

Given

[tex]\sqrt{x+2}[/tex] = - x ( square both sides )

x + 2 = (- x)² = x² ( subtract x + 2 from both sides )

0 = x² - x - 2 ← in standard form

0 = (x - 2)(x + 1) ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x + 1 = 0 ⇒ x = - 1

As a check

Substitute these values into the equation and if both sides are equal then it is a solution.

x = 2 : left = [tex]\sqrt{2+2}[/tex] = [tex]\sqrt{4}[/tex] = 2, right side = - 2 ← not equal

Thus x = 2 is an extraneous solution

x = - 1 : left = [tex]\sqrt{-1+2}[/tex] = [tex]\sqrt{1}[/tex] = 1 , right side = - (- 1) = 1 ← equal

Thus the solution is { - 1 } → B

Answer:

$15.5

Step-by-step explanation:

let a = price of one orchid plant

8 orchids would cost 8 x a = 8a

12 orchids would cost 12 x a = 12a

Let b = price of one lily plant

12 lilies would cost 12 x b = 12b

8 lilies would cost 8 x b = 8b

8a + 12b = 362 -- eqn 1

12a + 8b = 388 -- eqn 2

to solve, multiply equation 1 by 8 and equation 2 by 12

64a + 96b = 2896 equation 3

144a + 96b = 4656 equation 4

substract equation 4 from 3

80a = 1760

a = $22

Substitute for a in eqn 1 and solve for b

8(22) + 12b = 362

b = $15.5

Answer:

Step-by-step explanation:

Answer:

50 degrees

Step-by-step explanation:

Given

<A = 20 + x

<B = 10+2x

Since <A and <B are supplementary then the sum of their angles is 180 degrees

<A + <B = 180

20+x + 10+2x = 180

30+3x = 180

3x = 180-30

3x = 150

x = 150/3

x = 50 degrees

Hence the value of x is 50 degrees
