Write an Equation and solve for x.

Answers

Answer:

x = 17

Step-by-step explanation:

The angles 3x + 1 and 4 + 2x MUST total 90 degrees:

5x + 5 = 90 degrees

or:  5x = 85 degrees

therefore:  x = 17

Answer:

x=17

Step-by-step explanation:

(3x+1)+(4+2x)=90

3x+1+4+2x=90

5x+5=90

5x + 5 - 5 = 90 - 5

5x = 85

5x/5 = 85/5

x = 17

Name a fraction that is equivalent to three twelfths and also has a denominator that is less than 12. Explain how you found your answer.

Answers

5: six twelfths is one half

6: eight tenths is four fifths

7: four eighths is one half

8: ten tenths is two halves

9: two sixths is one third

10: one quarter, because you divide the top and bottom number by 3

method:

take the first one - four eighths, which is 4/8

the question gives you what to divide them by, 4, so u divide both the top number and bottom number to get 1/2, which is one half :)

Dividing by 6 - six twelfths(6/12) = 1/2(one half)

Dividing by 2-  eight tenths(8/10) = 4/5( four fifth)

Dividing by 4 - four eighths(4/8) = 1/2 (one half)

Dividing by 5- ten tenths(10/10) = 1 = two halves(2/2) =1

Dividing by 2 -two sixths(2/6) = 1/3(one third)

Which idea is unsupported by the authors main arguments about Benjamin Franklin's accomplishments?Benjamin Franklin's Fascination with Electricityadapted from the National Park Service Benjamin Franklin was fascinated by electricity and gave a lot of his time after he retired to study its properties. Some of his research resulted in "tricks" that he used to amuse others. For example, he made a charged metal spider that moved like the real thing. He discovered new ways to generate, store, and turn on electricity. His design of lightning rods helped prevent untold numbers of structural fires throughout the world. His famous kite experiment occurred in June 1752. Franklin asked his son William to fly a kite to which he had attached a wire on top and a key at the end of a string. Ultimately, the kite gathered an electric charge from a storm cloud. Franklin was then able to collect some of the charge and compare it to the electricity he had created in other experiments. He did not mention the experiment until October, four months after it took place, at which point Franklin did not clarify that he had conducted the experiment himselfan issue that has caused some people to doubt Franklin's story.A-Paved the way for theoriesB-Never patented any of his inventionsC-Largely self-educatedD-the only president who was never elected president50 Points why do players choose to follow the unconventional route of kicking down the middle Find AY.
