Answer:
F
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 5500 × 0.06 × 2.5 = 825
I = $ 825.00
The simple interest accumulated
on a principal of $ 5,500.00
at a rate of 6% per year
for 2.5 years is $ 825.00.
Explanation:
The given <em>expression</em> is not an <em>equation</em>. There is nothing that can be <em>solved</em>.
___
An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.
For example, we might have ...
5n +1 = 1
Your familiarity with math facts means you know that ...
0 +1 = 1
In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is <em>n = 0</em>, because 5×0 + 1 = 1 is a true statement.
___
An <em>expression</em> can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.
To evaluate 5n+1 for n=6 we put 6 in place of n:
5×6 +1
Doing the arithmetic, we get ...
= 30 +1 = 31
The value of 5n+1 for n=6 is 31.
To obtain an overall average of 86%, a score of 96 is required on her 4th test.
Let the required score on her fourth test = t
The required average = 86%
Initial scores : 80% + 83.5% + 84.5%
Average = ΣX/ (fx)
fx = total score obtainable = 4 × 100 = 400
ΣX = sum of scores
Average = 86%
0.86 = ((80 + 83.5 + 84.5 + t) / 400)
86 = (248 + t) / 400
400 × 0.86 = 248 + t
344 = 248 + t
344 - 248 = t
96 = t
In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

Step-by-step explanation:
the line passing through the points (-7, - 7) and (4,-7).
Slope: (-7+7) /(4+7) = 0/11 = 0
this is a horizontal line
through the points (4,7) and (4, -6).
slope: (-6-7) /(4-4) = -13/0 = oo
this is a vertical line
