Answer:

\boxed {\tt 90 \%}

Step-by-step explanation:

The average can be found by adding up all the values and dividing by the number of values.

1. Add the values

The values are her five test scores: 100, 95, 75, 100, 80

Add them : 100+ 95+75+100+80 = 450

2. Divide by the number of values

She took five tests, so there are five values. Divide 450 by 5.

450/5=90 = 90%

Her average grade is 90%

Answer:

average grade = 90%

Step-by-step explanation:

to find the average: add all the grade points up and divide it by the # of grades listed (in this case, 5)

100 + 95 + 75 + 100 + 80 = 450

450/5 = 90

average grade = 90%

\\ \sf\longmapsto L-M

  • Put values

\sf \left[\begin{array}{cc}\sf 4&\sf 6\\ \sf 5 &\sf 8 \\ \sf 3 &\sf -2\end{array}\right]-\left[\begin{array}{cc}\sf 2&\sf 3\\ \sf 1 &\sf 4 \\ \sf -5&\sf3\end{array}\right]

Just substract corresponding terms

\\ \sf\longmapsto \left[\begin{array}{cc}\sf 2 &\sf 3\\ \sf 4&\sf4\\ \sf 8&\sf -5\end{array}\right]

PLEASE HELP!!<br> How many solutions can be found for the equation −4x − 11 = 2(x − 3x) + 13?
PilotLPTM [1.2K]

Answer: No~Solutions

Step-by-step explanation:

Let's factor then solve to find the complex solutions.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : -4x-11=2(x-3x)+13

Equations that are never true:

1.1     ~~~~ Solve :    -24   =  0

This equation has no solution.

A non-zero constant never equals zero.

<u><em>Therefore your answer is </em></u>No~Solution
