margos grade average in math 92. Then for seven month her average dropped an average of five-eighths of a point per month. write a rational number expression involving addition that you can evaluate to find her average at the end of seven months. what was her final average.

Answers

Answer 1

Answer: it is probably around 50 or close to that

Answer 2

Answer:

Final answer:

To find Margos's average at the end of seven months, subtract the average drop in points per month from her initial grade average.

Explanation:

To find Margos's average at the end of seven months, we need to subtract the average drop in points per month from her initial grade average. Since her average dropped by an average of five-eighths of a point per month, we can write this as a rational number expression: 92 - (5/8 * 7). To evaluate this expression, we first multiply 5/8 * 7 = 35/8. Then we subtract this from 92: 92 - 35/8. To subtract these fractions, we need a common denominator: 92/1 - 35/8 = 736/8 - 35/8 = (736 - 35)/8 = 701/8.

So Margos's final average after seven months is 701/8 or 87.625.

Fold the slope 2x+y=10

Answers

Answer:

Step-by-step explanation:

slope=m

mx+y=10

2x+y=10

How do you find the slope of the line 2x+y=10?

Change the equation to slope-intercept form, y=mx+b , where m is the slope and b is the y-intercept.

2x+y=10 Subtract 2x from both sides.

y=−2x+10 The slope is −2 .

Will the sum of two linear expressions each with an x-term , always,sometimes,or never have an x-term ? Explain your reasoning

Answers

The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.

Examples:

-- Two linear expressions:

   y + x
and
   y + 2x

The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.

   (y + x) + (y + 2x) = 2y + 3x .
_______________________________

Two different linear expressions:

   y + 3x
and
   y - 3x

The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.

   (y + 3x) + (y - 3x) = 2y .
