I need help and I don't know what to do

Answers

Answer 1

Answer: i think combine like terms
12x+10x+3x+2x -y+y+5y
X=27 Y=5y

Answer 2

Answer: any two opposite angles are equal so,
12x - y = 10x +5y
12x-10x = 5y+y
2x = 6y
so x=3y ----> eqn.1

and, the sum of all angles are equal 360 degrees
so 12x-y + 2x+4y + 10x+ 5 y + 3x + y = 360 then , 27x + 9y = 360 substitute by y= x/3 from eqn.1 the 27x +9(x/3) = 360 27x+3x=36030x=360x=12 substitute in eqn.1 y=x/3 y=12/3y=4 so we get x = 12 & y = 4

B. 6/41
C. 41/60
D. 11/12

Answers

Add all the fractions together:
to do this find the lcd:
which is 60
1/10 = 6/60
1/4= 15/60
1/5= 12/60
2/15= 8/60
add them together
(6+15+12+8)/60
41/60 or C is the answer

C is the right answer
Thank you

How many terms are in this equation
8y-6y^2/7^3

Answers

Answer:

Step-by-step explanation:

You count terms that are seperated by - and + signs. Any type of fraction is considered one term.

So you count 8y as one term and the rest is a whole fraction so you also count that as one term.

You add all the terms together and you have 2 terms in this equation.

Hope this helped :)

What is the main reason that people are hesitant to use nuclear energy a. It produces radioactive waste. b. It uses large amounts of water. c. The ore used for nuclear energy must be mined. d. It is more damaging to natural habitats than the use of coal.

Answers

Nuclear energy is FEARED due to production of radioactive waste. Expose to radioactive waste have already taken place like Fu.kushima nuclear power station (March 2011) and more famously known; Chernobyl (April 1986). Nuclear waste is dangerous for over tens of thousands of years! For humans, radioactive waste breaks up our DNA. Either damaging our cells, or MUTATING them, which eventually lead to cancer and ever death.

The main reason that people are hesitant to use nuclear energy is It is more damaging to natural habitats than the use of coal.

What is nuclear energy?

Nuclear energy refers to the energy that is obtained from the nucleus of an atom. It is the energy that that can be obtained from a fusion or a fission reaction.

However, there are many uncertainties that surround the use of nuclear energy especially the posibility of a nuclear disaster. Hence, the main reason that people are hesitant to use nuclear energy is It is more damaging to natural habitats than the use of coal.
