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.

A chair that cost $210 was reduced by 40% for a one day sale after the sale, the sale price was increased by 40% what is the price of the chairEnter

Answers

The price of the chair afterwards was $176.40. You take $210 and multiply it by .40 and get $84. Then you subtract it from 210 and get 126. Then take 126 multiply it by .40 and get $50.40 then you add it back to the $126 and get $176.40

The best way to find percent is to use proportion. After using proportion your answer would probably be 84$. Remember the percent always goes over 100. so u would put 40 over 100 and 210 under n which is the part you don't know.

0.007 is 1\10 of what because I don't make sense

Answers

0.007 x 10 = 0.07

In the scientific value of 5.893 x 10n. The standard value is 0.00005893 what is n? To better illustrate this phenomenon, we can explain it further under the rules of scientific notation.
For example.
1.  3 x 10^3 = 3 x 100 = 300
2.  3 x 10^-3 = 3 x 0.001 = 0.003

Solution:
0.00005893 = 5.893 x 0.00001 = 5.893 x 10^-5
n= ^-5

Answer:

it dosnt make sense because 0.007 is 10x 0.07
