Henry has completed 40% of his work, leaving him with a remaining 60%.

What you do is divide 20 by 50 and your answer is .4, move the decimal two places to the right to get your percent, 40. Then subtract it out of 100 and you get the remaining 60%, which essentially is your answer.

URGENT!!! PLEASE HELP

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

Answer:

a=3,b=7,c=-20

Step-by-step explanation:

we are given equation as

3x^2=20-7x

Firstly, we will move all terms on left side

Subtract both sides by 20

3x^2-20=20-7x-20

3x^2-20=-7x

Add both sides by 7x

3x^2-20+7x=-7x+7x

3x^2-20+7x=0

3x^2+7x-20=0

now, we can compare it with quadratic equation

ax^2+bx+c=0

and we get

a=3,b=7,c=-20
