-8x -8x
-15x (÷ -15) = -15 (÷ -15)
x = 1
Answer:
x = 1
Step-by-step explanation:
18 = 3 + 15 x
15 = 15x
x = 1
PLUG IN THE 1 TO CHECK:

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180
Answers
Answer:
because its a straight line
Step-by-step explanation:
Answer:
Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.
(2x-7)+(x+25)+(3x+12)=180
6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.
6x=150 subtract 30 from both sides of the equation
x=25.

Answers
Answer: 50
Step-by-step explanation:
5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

Henry's dog ate 8 cans of dog food this week. Each can contain 55.4 grams of protein. How much protein was this in all?
Answers
Answer:
443.2 grams
Step-by-step explanation:
Each can contains 55.4 grams of protein, and there are 8 cans, so the answer would be 55.4*8 = 443.2 grams.
Since there are each can had 55.4g of protein, and Henry’s dog ate 8 of them, you can think of it as 55.4 • 8 = 443.2
Aisha measures the length of a sheet of paper and finds that it is 29 cm long. The label on the package indicates that the paper length is 32 cm. Calculate the percentage error in the measurement.
Answers
Answer:
just do the step by step and you'll probably get it because it's quite simple but hard for me to explain so just read this!
Step-by-step explanation:
In making any measurement, the chances are that our results will not be absolutely accurate. We can often compare our results with some standard or accepted value to see how closely they agree. But how much error can be allowed before the result becomes meaningless?
As you may guess, the amount of error that is acceptable varies with the situation. Suppose you measure the distance on a map between your Scarsdale and Mamaroneck and you get a result of 5 miles. If the actual distance is 5 1/2 miles, the chances are this error will have no effect on the trip between the two towns. But if the same degree of error existed in the calculations used to send astronauts to the moon, those people would be in big trouble!
Percentage Error = measured value - accepted value x 100%
accepted value
Suppose, you measured the length of a table and obtained a measurement of 202 cm. A friend also measures the table and obtains a result of 198 cm. To calculate the percentage error in each of the measurements, you need to know the "correct' or “accepted value” of the length of the table. After consulting the manufacturer’s catalog, you find that the table's length is listed as 200 cm in length. This will be used as the accepted value in our calculation.
The calculations of percentage error for the two measurements are shown below. Both measurements show an error of 1%. Your friend has made a measurement which is on the low side of the accepted value and is therefore, negative. You, on the other hand, have made an error on the high side of the accepted value and it is positive.

Thanks anyways.
Answers
Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X
Answers
Explanation: The anglers in a triangle must all add to 180.
Therefore, we can use the equation 180=3x+28+5x+52+2x-10
Combing like terms gives us 180=10x+70
Solving for x gives us 11.
To check our work, we can plug in 11 for x.
3(11)+28+5(11)+52+2(11)-10=180.
