Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180°     then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180         subtract 10 from both sides

        -10     -10

10x = 170            divide each side by 10

/10     /10

x = 17

Answer:

1:4

Step-by-step explanation:

Since the first circle has an area of 50.24 and the second circle is 4 times that, the ratio is 1:4 because for every 50.24 units of the first circle, there are 200.96 units of the second circle (which is 4 times the amount of the first circle).

the first x < 3 so x could be from - 1 till 3 in this graph

the other x > - 7 so x could be from from - 7 till - 3 in this graph

Answer:

x = 25.46

Step-by-step explanation:

Answer: D. y = 3x + 2

Step-by-step explanation: because that's what it shows in the graph

Answer:

D. y = 3x + 2

Step-by-step explanation:

y = mx + b,

where m = slope = rise/run,

and b = y-intercept

From the graph we see that b = 2, s we have

y = mx + 2

Now we look for the slope. Start at (0, 2), the y-intercept, go up 3, a rise of 3, and right 1, a run of 1 to the next point on a grid line intersection.

m = slope = rise/run = 3/1 = 3

Now we have

y = 3x + 2

Answer: D. y = 3x + 2

I'm sorry for not answering but have you got the answer to this question

Answer:

yes

Step-by-step explanation:

For the given sides to form a triangle.

The sum of any 2 sides must be greater than the third side.

12.2 + 6.8 = 19 > 6.5

12.2 + 6.5 = 18.7 > 6.8

6.8 + 6.5 = 13.3 > 12.2

Thus the 3 given sides form a triangle

Answer:

$10.25

Step-by-step explanation:

Set up a system of equations, so 3c + 2m = 7 and 2c + 4m = 8, where c = the cost of coffees, and m = cost of muffins

To solve multiply the first equation by -2(3c + 2m=7) so you get -6c -4m = -14 now add the two equations

-6c - 4m = -14

2c + 4m = 8   notice that -6c + 2c = -4c and -4m + 4m cancels, then -14+8=-6

so we have -4c = -6 so c = $1.50

To solve for m, substitute c = 1.50 so 3(1.50) + 2m = 7, so solve for m so

4.5 + 2m = 7, 2m = 2.5, so m = $1.25

So now solve the final problem 6(1.50) + 1(1.25) = $10.25

The value of x is 17

An equation between two variables that gives a straight line when plotted on a graph.

Given,

x represents a certain number

Number is multiplied by 3 = 3x

Adding 34 to the number = x+34

Given,

The number x is multiplied by 3 the result is the same as adding 34 to the number x​

Therefore

3x = x+34

3x-x =34

2x =34

x = 17

Hence, the value of x is 17

Step-by-step explanation:

Given [Missing Information]

[tex]Red = 12[/tex]

[tex]Blue = 10[/tex]

[tex]Green = 15[/tex]

[tex]Yellow = 13[/tex]

Way 1:

Add up the total marbles that are not red.

[tex]Not\ Red = Blue + Green + Yellow[/tex]

[tex]Not\ Red = 10 + 15 + 13[/tex]

[tex]Not\ Red = 38[/tex]

Divide by total marbles to get the probability;

[tex]Probability = \frac{Npt\ Red}{Total}[/tex]

[tex]Probability = \frac{38}{38 + 12}[/tex]

[tex]Probability = \frac{38}{50}[/tex]

[tex]Probability = 0.76[/tex]

Way 2:

Calculate the probability of choosing red

[tex]P(Red) = \frac{Red}{Total}[/tex]

[tex]P(Red) = \frac{12}{50}[/tex]

[tex]P(Red) = 0.24[/tex]

Apply complement rule (i.e. subtract it from 1)

[tex]P(Not\ Red) = 1 - P(Red)[/tex]

[tex]P(Not\ Red) = 1 - 0.24[/tex]

[tex]P(Not\ Red) = 0.76[/tex]

Answer:

degree 3

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of the term within the polynomial.

4x²y = 4x²[tex]y^{1}[/tex] ← with exponent 2 + 1 = 3

x² ← exponent 2

- 2y² ← exponent 2

The term with the largest exponent is 4x²y with exponent 3

Then the polynomial is of degree 3

Please find the full question in the attached image

the area of rectangle is length x breadth. The area of each room would be found and the three areas would be added together

for example ,

dimension of room 1 = 5 x 3

dimension of room 2 = 2 x 3

dimension of room 3 = 4 x 5

area of room 1 = 15

area of room 2 = 6

area of room 3 = 20

total area = 15 + 6 + 20 = 41

Answer:

100 miles

Step-by-step explanation:

Given data

let the number of miles driven be x

and the total charge for x miles be y

Hence the expression for the total charge is

Rapid Rental Car

charges a $55.00 rental fee plus $0.25 per mile driven.

y= 55+0.25x--------------1

Capital Cars charges a $45.00 rental fee and $0.35 per mile driven.

y= 45+0.35x--------------2

Equate 1 and 2

55+0.25x= 45+0.35x

collect like terms

55-45=0.35x-0.25x

10=0.1x

x= 10/0.1

x= 100 miles

Hence the mile is 100 miles

Answer:

32

Step-by-step explanation:

Answer:

a; 3.45 * 10^3

b) 2.34 * 10^18

c) 80%

Step-by-step explanation:

a) 3450 in standard form

To write in standard form, we have to place a decimal at the back of the first non-zero number

we have this as ;

3.450

The count of numbers after the decimal point is 3

This will be the power to which 10 will be raised

We have this as;

3.45 * 10^3

b) 234 * 10^16

Let us write 234 in standard form

That will be;

234 = 2.34 * 10^2

So we have ;

2.34 * 10^2 * 10^16

Using the law of indices, we have;

2.34 * 10^(2 + 16) = 2.34 * 10^18

c) From the question, Kuwait is 4/5 of Hong kong’s population

Let Honk Kong’s population be x

4/5 * x = 2.4 million

4x = 5 * 2.4 million

x = 5 * 2.4/4

x = 5 * 0.6

x = 3 million

so writing the population of Kuwait as a percentage of that of Hong kong, we have

2.4/3 * 100%

= 0.8 * 100% = 80%
