Answer:
a=3 x= all reals
Step-by-step explanation:
I actually did not get 6 for an answer
4x+a=4x+3
cancel equal terms on both sides of the equation
a=3
which means the x would be all reals cause it is true.
What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°
Decrease £120 by 12.5%
Answer:
£ 105.
Step-by-step explanation:
Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:
100 - 12.5 = 87.5
100 = 120
87.5 = X
87.5 x 120/100 = X
10,500 / 100 = X
105 = X
Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

A class was conducting a series of probability experiments.
Which set of events would have an equally like chance of occurring?
A
spinning a spinner with 3 sections and tossing a coin.
B
rolling a six-sided cube and drawing 6 marbles out of a bag.
С
tossing a coin and choosing an odd number between 1 and 7
D
drawing 1 card out of 25 cards and choosing a letter out of the alphabet.
Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.
Option B is correct.
Probability:Probability of series of experiments shown below;
A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .
When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]
So that, set A has not equally like chance of occurring.
B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]
When one marble is drawn out of 6 marble in a bag, then probability is [tex]\frac{1}{6}[/tex]
Therefore, set B has equally like chance of occurring.

Step-by-step explanation:
Step 1: Simplify both sides of the equation.
12x+2.2=−4
Step 2: Subtract 2.2 from both sides.
12x+2.2−2.2=−4−2.2
12x=−6.2
Step 3: Divide both sides by 12.

How many solutions can be found for the equation 5x + 3(x - 1) = 10x - 2x - 3?
None
One
Two
Infinitely many
Answer:
Infinitely many
Step-by-step explanation:
Equation: 5x + 3(x - 1) = 10x - 2x - 3
1) 5x + 3x - 3 = 10x - 2x - 3
2) 8x - 3 = 8x - 3
3) 8x = 8x
4) x = x
Based on this information, it seems that the best answer would be infinitely many solutions.

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride?
Answer:
8
Step-by-step explanation:
You can solve this by creating a linear equation.
Slope: 2.50
Y-intercept: 4.70
y=2.50x+4.70
Since we know that the total fare was 24.70 we can plug it into the y.
24.70=2.50x+4.70
Now solve for the equation.
20=2.50x
8=x
So he went 8 miles with the taxi.
Total number or mile taxi run is 8 miles.
Given that;
Pick up charge = $4.7
Charges per mile = $2.5 per mile
Total fare = $24.7
Find:
Number of mile taxi ride
Computation:
Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]
24.7 = 4.7 + [Total number or mile taxi run][2.5]
[Total number or mile taxi run][2.5] = 24.7 - 4.7
[Total number or mile taxi run][2.5] = 20
Total number or mile taxi run = 20 / 2.5
Total number or mile taxi run = 8 miles

535.78
Step-by-step explanation:
Dont how to explain
Need help plz. Don't answer for points or you will be reported!
Step-by-step explanation:
13.
Supplementary angles = 180º (theorem)
Set <ABD + <DBC = 180º
2x + (x+24) = 180º
add like terms = 3x+24=180
3x=156
x = 52
now plug in x for both angles
<ABD = 2(52) = 104
<DBC = 52+24 = 76
14.
complementary angles = 90º (theorem)
set <EFG + <GFH = 90º
y-32 + y = 90
2y - 32 = 90 : combine like terms
2y = 122
y = 61
now plug in y for both angles
<EFG = 61-32 = 29
<GFH = 61
15.
Vertical angles are equal to each other (theorem)
<PQR = <TRS
38 = 5w-7
45 = 5w
w = 9
plug into <TRS
<TRS = 5(9) - 7 = 38
(Also since you know that <PRQ is 38 and that the measure has to be the same for both angles, it can be assumed without algebra that <TRS would be 38º)
