To add or subtract numbers with the power of ten you need to make sure the exponents match before you do anything to the coefficients

Answer:

Step-by-step explanation:

Angle 21  is calculated like this:

180 - 70 - 50 = 60 because a line is 180 degrees.

Angle 22 = 50 degrees because it is opposite to the upper angle of 50 degrees.

Angle 23 = 70 degrees because it is also opposite to the upper angle of 70 degrees.

The sum of the angles would be

60 + 50 + 70 = 180 degrees

Answer: i believe it is 12x²−2x−2

Step-by-step explanation:

(4x−2)(3x+1)

=(4x+−2)(3x+1)

=(4x)(3x)+(4x)(1)+(−2)(3x)+(−2)(1)

=12x²+4x−6x−2

=12x²−2x−2

Answer:

16 pieces of pizza when the pizza was whole.

Step-by-step explanation:

You know that 6 pieces are equal to 3/8 of the pizza.

Let x represent the total number of pieces and write an equation:

3

-- times x = 6

8

Multiply each side of the equation by 8:

8 times 3

            -- x = 8 times 6

            8

3x = 48

Divide each side of the equation by 3:

3x     48

---  =  ---

x = 16

Answer:

$19.60

Step-by-step explanation:

245 is 100% of the total.

x is 108% of the total.

245/100 = x/108

245(108) = 26460

26460/100 = 264.6

264.6 - 245 = 19.6

So, we know that the internal angles of a triangle add up to 180 degrees, yes?  

60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.

Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!

Step-by-step explanation:

(x-8)+11= (answer)

The correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.

To determine which of the ordered pairs is not from the function f(x) = -3x + 4, we need to substitute the x-value of each ordered pair into the function and check if it matches the corresponding y-value.

A. (2, -2)

Substituting x = 2 into the function: f(2) = -3(2) + 4 = -6 + 4 = -2

The y-value (-2) matches the given ordered pair. This is a valid solution.

B. (5, -11)

Substituting x = 5 into the function: f(5) = -3(5) + 4 = -15 + 4 = -11

The y-value (-11) matches the given ordered pair. This is a valid solution.

C. (-3, 13)

Substituting x = -3 into the function: f(-3) = -3(-3) + 4 = 9 + 4 = 13

The y-value (13) matches the given ordered pair. This is a valid solution.

D. (-6, 21)

Substituting x = -6 into the function: f(-6) = -3(-6) + 4 = 18 + 4 = 22

The y-value (21) does not match the given ordered pair (-6, 21). This is not a valid solution.

Therefore, the correct answer is D. (-6, 21), as it is not an ordered pair from the function f(x) = -3x + 4.

Answer:

  (g, b) = (70, 0), (56, 10), (42, 20)

Step-by-step explanation:

The g-intercept is 35/0.5 = 70, so (g, b) = (70, 0) is a possible combination.

The slope of the relation is such that when g goes down by 14, b goes up by 10. Other points on the line are (70 -14, 0 +10) = (56, 10) and (56 -14, 10 +10) = (42, 20).

Of those listed, the possible combinations are ...

  (g, b) = (70, 0), (56, 10), (42, 20)

Answer:

The equation for slope-intercept form is y=mx+b In this form, m is the slope of the line and the b is the y-intercept. or rise/run

Answer:

t = 39

Step-by-step explanation:

the diagonals of a parallelogram bisect each other, therefore t = 3t - 78 further solving this equation we get

2t = 78 and then t = 39

Answer:

For the first picture, x = 126 and therefore x - 30 = 96

Second picture:

Step-by-step explanation:

since the sum of the angles is 540°, we can say that

x + x + (x - 30) + (x - 30) + (x - 30) = 540

5x - 90 = 540

5x = 630

x = 126

therefore x - 30 = 96°

_____________________________________

2nd picture

we use the same method as we did in the first picture:

5x + 2x + 110 = 180

7x + 110 = 180

7x = 70

x = 10, 5x = 50, 2x = 20

Final amount= $13200

Required:

The time t

Step two

The expression for the compound interest is

[tex]A= p(1+r)^t[/tex]

t = ln(A/P) / r.

substitute

t = ln(13200/9500) /0.05

t= ln(1.39)/0.05
