Does anyone know how to solve this?
A triangle has angles described as follows: The measure of the first angle is two more than nine times a number, the measure of the second angle is five less than the first, and the measure of the third angle is 19 times the number more than the second angle. What is the measure of each angle in degrees?
Answers
Answer:
x = measure of the first angle
2x -5 = measure of the second angle
3x - 19 = measure of the third angle
the sum of the measures of a triangle is 180 degrees
x + (2x-5) + (3x-19) = 180
6x - 18 = 180
x = 33 (first angle)
2x - 5 = 2 (33) -5 = 61 (second angle)
3x - 19 = 3 (33) - 19 = 86 (third angle)

You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 3.1 feet long, if the remaining piece needs to be 2.27 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth
Answers
Answer:
the answer might be 20
Step-by-step explanation:
first you add 3.1 to 3.1 to get 6.2
then you multiply 6.2 by 2.27
then you add the answer you get from that to 3.1+3.1 to get the final length to be 20.274 and that would be 20 in the nearest tenth

Answers
Answer:
x is all real numbers
Step-by-step explanation:
4(x + 1) = 4x + 4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions

727÷9 Pleaase HEEEELLLPPP!!!!!!!!
Answers
Answer:
80.77777778
Step-by-step explanation:
when dividing 727 by 9, think about how many times does 9 go into 7? none.
next how many times does 9 go into 72? 8 times!
but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

In a triangle, two angles have measures of 45 degrees and 85 degrees. What is the measure of the third angle in this triangle?
Answers
Answer:
50 degrees
Step-by-step explanation:
All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.
45+85=130. Then, subtract 130 from the total, or 180. 180-130=50. The measure of the third angle of the triangle is 50 degrees.

(a) Write a sentence of interpretation for
g(4) = 13.10.
Answers
The answer is "The local inventory car racing team used 1310 gallons of engine oil in July".
The function consists of 3: input, output, as well as the relationship between the two.The interpretation of a mathematical formalism is to derive important data from a line chart or given symbolic image.Therefore, the amount of oil that the regional sports car racing team is using during the month is G(t), which is 100 gallons, wherein T is the number of months that very last March.Given:
[tex]\to \bold{g(4) = 13.10}[/tex]
If [tex]\bold{g(4)=13.10}[/tex] means that [tex]\bold{1310 }[/tex] gallons of motor oil was used by the local stock car racing squad in July.So, the final answer is "The local inventory car racing team used 1310 gallons of engine oil in July".Learn more:
