Okay so the first thing we are going to do is change
into a improper fraction:
.
=224÷25=8.96
as a decimal is
.
Answer:
x=3
Step-by-step explanation:
There's many ways you can begin this, I prefer getting rid of the fraction first.
Multiply both sides by 3/2 (yes, I switched it on purpose)
You get. . .
5x-6 = 9
To isolate the 5x, add 6 to both sides
5x = 15
Divide both sides by 5 and you get . . .
x=3
Answer:
The slope is -3/2
Step-by-step explanation:
<u>A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal.
</u>
Example: Find the line perpendicular to y = 3x
First, you flip the sign which makes 3 into -3
Next, you make the reciprocal which makes -3 into <u>-1/3
</u>
Problem: Find the line perpendicular to y = (2/3)x + 7
First, you flip the sign which makes 2/3 into -2/3
Next, you make the reciprocal which makes -2/3 into <u>-3/2</u>
Answer: The slope is -3/2
10! If you use the trapezoid area formula and plug in the known values, just solve for h(height)
