As a rule , - times - = + and - times + = -

\begin{gathered} -16m^2n-(-25m^2n)+(-7m^2n\text{ ) } \\ =-16m^2n+25m^2n-7m^2n\text{  ( based on the rule above )} \\ =+9m^2n-7m^2n\text{    ( -16 + 25 = + 9 )} \\ =+2m^2n \end{gathered}

Therefore the correct answer to the question is 2m squared n

viktelen [127]

Answer:

B) one solution

Step-by-step explanation:

The blue line and the red line cross at only one point so there is one solution. It would be no solution if the blue line never crossed the red line and it would be two or possibly more solutions if the lines crossed more than once.

25% of 400 is equal to 20% of What?
Bess [88]

Here is your answer:

First find 25% of 400:

  • 400/x=100/25
  • (400/x)*x=
  • (100/25)*x
  • x 400=4*
  • 400/4=x  
  • 100=x  
  • x=100

The answer is "500."

  • 100 ÷ 20%
  • 100 ÷ (20 ÷ 100) =
  • (100 × 100) ÷ 20 =
  • 10,000 ÷ 20 =
  • = 500

Hope this helps!

CORRECT ANSWER GETS BRAINLIEST A frequency table of grades has five classes​ (A, B,​ C, D,​ F) with frequencies of ​4,11 ​,15 ​,
ra1l [238]

Answer:

A = 10.5%

B = 28.9%

C = 39.5%

D = 18.4%

F = 2.6%

Step-by-step explanation:

Add all the frequencies together = 38

  • 4/38 × 100 = 10.5%
  • 11/38 × 100 = 28.9%
  • 15/38 × 100 = 39.5%
  • 7/38 × 100 = 18.4%
  • 1/38 × 100 = 2.6%

10.5 + 28.9 + 39.5 + 18.4 + 2.6 = 100%
