Answer:
w = 9
Step-by-step explanation:
We can use ratios to solve
2 3
---- = ------
6 w
Using cross products
2w = 3*6
2w = 18
Divide by 2
w = 9
The height of trapezoid is 18 yards
<em><u>Solution:</u></em>
Given that, trapezoid has an area of 342 square yards
The length of one base is 17 yards, and the length of the other base is 21 yards
To find: height of trapezoid
<em><u>The area of trapezoid is given by formula:</u></em>

Where "h" is the height
"a" and "b" are the length of base
Here given that,
area = 342 square yards
a = 17 yards
b = 21 yards
h = ?
<em><u>Substituting the values we get</u></em>,

Thus height of trapezoid is 18 yards
Answer:
2y-4-6y-12=4
-4y=20
y= -5
Step-by-step explanation:
because (y+2)(y-2)=y^2-4
so we have the step to let the every part have the same denominator y^2-4
2(y-2)/(y+2)(y-2) -6(y+2)/(y-2)(y+2)=4/(y-2)(y+2)
the denominators are the same so the equality .we just need the part over be the same 2y-4-6y-12=4
y= -5

Answer:

$570
Step-by-step explanation:
Given that:
For each hour of tutoring, Lena earns 30 dollars.
E is her earning and
H is the number of hours for which she tutors.
To find:
Equation relating E to H.
Solution:
Let Lena tutors for 1 hour, then the earning = 30 dollars
Let Lena tutors for 2 hours, then the earning = 30+30 OR 2
30 = 60 dollars
Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 3
30 = 90 dollars
If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.

So, the equation that relates E to H is given as:

Now, it is given that she tutors for 19 hours.
Let us put H = 19 hours in the above equation:

Therefore, the earning for 19 hours of tutoring is <em>570 Dollars.</em>
