60 divided by 5 is 12 then you multiply 2 which is 24:)

Answer:

2nd option

Step-by-step explanation:

The ratios on both sides must be equal

[tex]\frac{15}{6}[/tex] ( divide numerator/ denominator by 3 )

= [tex]\frac{5}{2}[/tex] ≠ [tex]\frac{3}{2}[/tex] , then not a proportion

[tex]\frac{4}{5}[/tex] ( multiply numerator/ denominator by 3 )

= [tex]\frac{12}{15}[/tex] , this is a proportion

[tex]\frac{9}{21}[/tex] ( divide numerator/ denominator by 3 )

= [tex]\frac{3}{7}[/tex] ≠ [tex]\frac{6}{7}[/tex] , then not a proportion

[tex]\frac{10}{16}[/tex] ( divide numerator/ denominator by 2 )

= [tex]\frac{5}{8}[/tex] ≠ [tex]\frac{2}{8}[/tex] , then not a proportion

Answer:

1. 18/8

2. 16/20

3. 15/28

4. 12/24

Answer:

< 1 is 85

X= 50

Step-by-step explanation:

ok the first question has 2 angles given 60 and 65

consider this one shows a 90 degree angle and the other does not. so  60 plus 90 equals 150 degrees

the u must say 65 plus x (x being angle 1) must also equal 150

subtract 65 from 150 and you get 85

now the second problem lets use the

Exterior Angle Theorem

The measure of an exterior angle (our w) of a triangle equals to the sum of the measures of the two remote interior angles (our x and y) of the triangle.

using this we know the 40 degree angle and 2x + 20 equals 3x plus 10

so we subtract 10 degrees from both sides and get

2x plus 10 plus 40 equals 3x now this means x equals 10 plus 40 which is 50

Answer:

C ≈ 54

Step-by-step explanation:

The circumference (C) is calculated as

C = πd ( d is the diameter )

Here d = 18 , then

C = π × 18 ≈ 3 × 18 = 54

Based on the amount Maigan makes and the amount she spends on the phone per month, the relevant equation using the mentioned variables will be "T = 1,800 - 50m"

Maigan makes $1,800 and this is the source of the cost of the phone.

If she pays $50 per month, the relevant equation to find out the amount of money she would be left with after a number of months is:

= Amount started with - Amount spent per month x number of months

This can be written as:

T = 1,800 - 50 x m

T = 1,800 - 50m

In conclusion, the relevant equation would be T = 1,800 - 50m.

The quotient of the expression is [tex]\frac{1}{2y}[/tex]

The expression is given as:

[tex]\frac{3y^2}{3y} \div \frac{6y^4}{3y^2}[/tex]

Divide 3y^2 by 3y

[tex]\frac{3y^2}{3y} \div \frac{6y^4}{3y^2} = y \div \frac{6y^4}{3y^2}[/tex]

Rewrite the equation as a product

[tex]\frac{3y^2}{3y} \div \frac{6y^4}{3y^2} = y \times \frac{3y^2}{6y^4}[/tex]

Divide 6 by 3

[tex]\frac{3y^2}{3y} \div \frac{6y^4}{3y^2} = y \times \frac{y^2}{2y^4}[/tex]

Multiply y and y^2

[tex]\frac{3y^2}{3y} \div \frac{6y^4}{3y^2} = \frac{y^3}{2y^4}[/tex]

Divide y^3 by y^4

[tex]\frac{3y^2}{3y} \div \frac{6y^4}{3y^2} = \frac{1}{2y}[/tex]

Hence, the quotient of the expression is [tex]\frac{1}{2y}[/tex]

Answer: Neither A or B

Step-by-step explanation: In order for a relation to be a function, a relation can not have the x-values repeat. Y-values can repeat an infinite amount of times but x-values can only repeat 1 time in a given relation. In relation A, you have (2,-2), and (2,3) and relation B, you have (9,3), and (9,-3). You can also graph both of these relations and do a vertical line test with your pencil and see that it would cross more than once.

Hope this helps.

Answer:

Neither A nor B

Step-by-step explanation:

A function is a relation that has a unique x value for every y value. This means that the x-values will never repeat. So, to figure out if a list of coordinates is a function check the x-values. If they never repeat, then it is a function. However, in the case of both A and B, the x-values repeat. For, relation A the value 2 repeats, and for relation B the 9 value repeats. Therefore, neither are functions.

Step-by-step explanation:

The required numbers are -2.33 and 1 are a distance of 5/3 unit from -2/3 on a number line.

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

Here, we have,

We have been given that number line, the numbers that are 5/3 units away from the number -2/3 are the numbers that are 5/3 units to its right and left.

The numbers are given by -2/3 - 5/3 and -2/3 + 5/3.

So the required numbers would be:

⇒ -2/3 - 5/3 = -7/3 = -2.33

⇒ -2/3 + 5/3 = 3/3 = 1

Therefore, the required numbers are -2.33 and 1 are a distance of 5/3 unit from -2/3 on a number line.
