If you would like to solve 80% of 40, you can do this using the following steps:
80% of 40 = 80% * 40 = 80/100 * 40 = 32
The correct result would be 32.
Q1
I like to use the standard form to write the equation of a perpendicular line, especially when the original equation is in that form. The perpendicular line will have the x- and y-coefficients swapped and one negated (remember this for Question 3). Thus, it will be
... 5x - 2y = 5(6) - 2(16) = -2
Solving for y (to get slope-intercept form), we find
... y = (5/2)x + 1 . . . . . matches selection C
Q2
The given equation has slope -3/6 = -1/2, so that will be the slope of the parallel line. (matches selection A)
Q3
See Q1 for an explanation. The appropriate choice is ...
... B. 4x - 3y = 5
Q4
The given line has slope -2, so you can eliminate all choices except ...
... D. -2x
Q5
The two lines have the same slope (3), but different intercepts, so they are ...
... A. parallel
Answer:
3.5
Step-by-step explanation:
11.5 - 2.5 = 9
9 - 5.5 = 3.5
and scalene triange means none of the 3 sides are equal...
3.5 does not equal 5.5 or 2.5
