Answer:

a) x = 60. b) b = 110. c) x = 20. d) x = 30.

Explanation:

For question a, 2x and 120° are opposite (vertical) angles so they must be the same measure according to the vertical angle theorem by definition, given they are angles formed by the transversal cutting two parallel lines. 2x = 120, so x = 60.

For question b, 130° and b + 20 are corresponding angles of the transversal cutting parallel lines, so they must be the same measure according to corresponding angle theorem(same side, one angle inner, and the other exterior of that) by definition. Given that they are both pairs of the same angle, they must be corresponding angles. 130° = b + 20, b = 110.

For question c, 120° and 2x + 20 are same side interior angles so they must be supplementary(add up to 180°) by definition. This is on the *same side* of the transversal inside the two parallel lines cut by it. 120° + 2x + 20° = 180°, x = 20°.

For question d, They are also on the same side but on the left so the same property of corresponding angles applies, so 3x + 10, and 100° must be the same measure. Therefore 3x + 10 = 100°, and x = 30.

Answer:

  2.4 g/cm^3

Step-by-step explanation:

Density is the ratio of mass to volume (as the units g/cm^3 tell you). If you cut the marble in half, each piece will have half the mass and half the volume, so the density remains unchanged. It will still be ...

  2.4 g/cm^3

Answer: x= -10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4.5(8−x)+36=102−2.5(3x+24)

(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)

36+−4.5x+36=102+−7.5x+−60

(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)

−4.5x+72=−7.5x+42

−4.5x+72=−7.5x+42

Step 2: Add 7.5x to both sides.

−4.5x+72+7.5x=−7.5x+42+7.5x

3x+72=42

Step 3: Subtract 72 from both sides.

3x+72−72=42−72

3x=−30

-3, -3/2, 0, 5, 11

Answer:

-3, -3/2, 0, 5, 11

Step-by-step explanation:

Answer:

0.2

Step-by-step explanation:

C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.

So to find that you would divide y by x.

In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.

Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

Answer:

The difference quotient of f is 8. Option C

Explanation:

Difference Quotient

Given a function f(x), the difference quotient is defined as

[tex]\displaystyle d=\frac{f(h+h)-f(x)}{h},\ h\neq 0[/tex]

The function provided in the question is

[tex]f(x)=8x+1[/tex]

Find f(x+h) by substituting x by x+h:

[tex]f(x+h)=8(x+h)+1[/tex]

[tex]f(x+h)=8x+8h+1[/tex]

Now compute:

[tex]\displaystyle d=\frac{8x+8h+1-(8x+1)}{h}[/tex]

Operating:

[tex]\displaystyle d=\frac{8x+8h+1-8x-1}{h}[/tex]

Simplifying:

[tex]\displaystyle d=\frac{8h}{h}[/tex]

d=8

Answer:

Hey!

Your answer is C!

Step-by-step explanation:

1. You must divide, 650/10. This is equal to 65.

2. Subtract 65 from 650. You will end up with 585.

To represent the amount that is left would be 9/10...

Now just put the 2 together to form...

Answer:

5x5=25

Step-by-step explanation:

5 x 5

= 5(1 + 0) x 5(1 + 0)

=5(1 + 1 - 1) x 5(1 + 1 - 1)

=5(2 - 1) x 5(2 - 1)

=(10 - 5) x (10 - 5)

=5 x 5 :0

=> 5 x 5 = 5 x 5 = 25

Answer:

y  = [tex]\frac{7}{6} x - 5[/tex]

Step-by-step explanation:

 Given expression:

        6x + 7y  = -42

To find an equation perpendicular to this, it implies the slope must be a negative inverse of the given one.

Solution:

Equation of any straight line is given as;

        y  = mx + c

where x and y are the coordinates

                m is the slope

                c is the intercept

Let us now find the slope of the line;

          6x + 7y  = -42

              7y = -6x - 42

   divide through by 7 to give;

             y = [tex]-\frac{6}{7} x[/tex] - 6

The slope is  [tex]-\frac{6}{7}[/tex]

     A line perpendicular will have a slope of a negative inverse;

          - ( [tex]-\frac{7}{6}[/tex] ) = [tex]\frac{7}{6}[/tex]

The answer is A.

The expression that represents D is (q²+7)/f

The subject of formula is a way of representing a variable to represent all other variables in a function

Given the expression

Add 7 to both sides

fD - 7 + 7 = q² + 7

fD = q² + 7

Divide both sides by f

fD/f = (q²+7)/f

D =  (q²+7)/f

Hence the expression that represents D is (q²+7)/f

Answer:

Y=5/16x -3/4

Step-by-step explanation:

3/8 * 8/3y=(5/6x -2) *3/8

y=5/16x - 3/4

The standard form of the equation is  5x -16y = 2.

It is required to find the standard form.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

According to given question we have,

The least common multiple of the fraction denominators is 6. Multiplying by that gives

 16y = 5x -2

We can put this in standard form by adding 2-16y to both sides.

 5x -16y = 2

Therefore, the standard form of the equation is  5x -16y = 2.

Answer:

Cost of chip cookies  = $17.5

Cost of ginger cookies  = $19.5

Step-by-step explanation:

Assume;

Cost of chip cookies  = c

Cost of ginger cookies  = g

So,

Maya's sales = 8c + 12g = 374 .....Eq1

Carlo's sales = 2c + 4g = 113 .......Eq2

4 x eq2

So

8c + 16g = 452......Eq3

Eq 3 - Eq 1

4g = 78

g = 19.5

and

c = 17.5

Cost of chip cookies  = $17.5

Cost of ginger cookies  = $19.5
