There are 10 total numbers.
10 - 7 = 3, so there are 3 numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Answer:
$75.6
Explanation:
If the original cost was $70 and it was marked up 20%, the price after this is calculated as:
$70 + $70(0.2) = $70 + $14 = $84
Where $70(0.2) = $14 is the amount added to the original when it is marked up 20%.
Then, it was discounted 10%, we get that the selling price is
$84 - $84(0.1) = $84 - $8.4 = $75.6
Where $84(0.1) = $8.4 is the discount made on the initial price.
Therefore, the answer is $75.6
The answer is 65.45 meters
Answer:
Given equation are:
......[1]
.....[2]
- The two lines are parallel lines then their slopes will be equal.
- When two lines are perpendicular then, the slope of lines are the negative reciprocals of each other.
Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.
Slope
of equation of line in [1] is;
then;

Slope
of equation of line in [2];
Add both sides 2x we get;
-2x + 8y + 2x = 2x + 4
Simplify:
8y = 2x +4
Divide both sides by 8 we get;

then;

Therefore, the given two lines are neither parallel nor perpendicular.
Hope this helps but I think the answer could be : 157+25m=50+60m
