Explanation:
The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.
If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.
If n = 3, then -4+5n = -4+5*3 = 11 is the second term
and so on until you reach n = 10.
A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

last year, there were m pies baked for the bake sale. This year, there were 124 pies baked. Using m , write an expression for the total number of pies baked in the two years.
Answers
Answer:
→ Last year, there were m pies baked for the bake sale. This year, there were 215 pies baked. Using m , write an expression for the total number of pies baked in the two years.
Step-by-step explanation:
▶ Given :-
→ Last year, number of pies baked for bake sale = m.
→ This year, number of pies baked for bake sale = 215 .
▶ To find :-
→ The equation that represents the total number of pies baked for bake sale .
▶ Solution :-
→ Let the total number of pies baked for bake sale in two years be ‘x’ .

What is the number?
n = 7.75
n=2.125
n= -7.75
n=-2.125
Answers
Answer:
n=-7.75
Step-by-step explanation:
Based on the given conditions, formulate: 5.5+2×X=-10
Rearrange unknown terms to the left side of the equation:2x=-10-5.5
Calculate the sum or difference:2x=-15.5
Divide both sides of the equation by the coefficient of variable:x=-15.5/2
Multiply both the numerator and denominator with the same integer:-155/20
Cross out the common factor:-31/4
get the result: -7.75
Answer: -7.75

For questions #9 - 11 "finding the slope" of a linear (straight) line, recall the "tools" that we can use:
1) Given a Graph: Slope or "m" = rise/run from one (x, y) point to a second (x, y) point on the line
2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1
3) Given a "Table of Values": Choose any two (x, y) points in the table, then calculate the slope using the slope formula - Slope or "m" = y2 - y1 / x2 - x1
