Answer:

-1 = x + 2

-2 -2

-3 = x

x = -3

Answer 2

Answer:

-1=-x+2

first you need to get x by itself so you are going to move it to the other side. the way you do this is by subtracting 2.

-3=-x

then you need to divide out a negative 1

x=3

Ryan tried to solve the system of equations shown below.{3x−2y=11−1.5x+y=−4He concluded that the system has no solution. Which is the best evaluation of Ryan's conclusion?

A
He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.

B
He is incorrect. If the second equation is multiplied by 2 and subtracted from the first equation, the result is 6x−4y=19 , which has infinitely many solutions.

C
He is correct. For any positive value of x , the corresponding value of y is negative, which means the system has no solution.

D
He is incorrect. Both equations describe lines that have infinitely many solutions.

Answer:

I believe the answer is A

He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.

if 5 potatoes together have a mass of 1 kilogram and 8 pears together have a mass of 1,200 grams, which has the greater mass, a potato or a pear? explain

Answers

The potatoes because kilograms are bigger than grams

Final answer:

The pear has a greater mass than the potato.

Explanation:

To compare the mass of a potato and a pear, we need to convert the mass of each to the same unit. Since the mass of the potatoes is given in kilograms and the mass of the pears is given in grams, we need to convert the mass of the pears to kilograms. There are 1,000 grams in a kilogram, so the mass of the pears is 1.2 kilograms.

Comparing the mass of the potato and the pear, we can see that the pear has a greater mass of 1.2 kilograms, while the potato has a mass of 1 kilogram.

Therefore, the pear has a greater mass than the potato.
