Answer:
28 centimeters.
Step-by-step explanation:
Let w be width of desk.
We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.
Since the area of trapezoid is half the sum of parallel sides times its height.
, where
h= Height of trapezoid,
a and b= Length of parallel sides of trapezoid.
We have been given that the height of the trapezoid is the width of the desk.
Upon substituting our given vales in above formula we will get,
Therefore, the width of trapezoid is 28 centimeters.
A. all number greater than a will be to the RIGHT of a
b. all numbers less than a will be to the LEFT of a
we conclude that the solution for the given algebraic expressions are:
- J = -5
- s = -106
- t = 38
- r = -60
- a = 57

How to solve these algebraic expressions?</h3>
Here we have some simple algebraic expressions:
The first one is:
-25/J = 5
We want to solve this for J.
Remember that we can perform the same operation in both sides of the equation, then we cans tart by multiplying both sides by J.
(-25/J)*J = 5*J
-25 = 5*J
Now we can divide both sides by 5, so we isolate J:
(-25)/5 = (5*J)/5
-5 = J
We conclude that the solution is J = -5.
Now, similarly for the other equations we have that:
16 + s = -90
Here we subtract 16 in both sides:
s = -90 - 16 = -106
13 + t = 51
Here we subtract 13 in both sides:
t = 51 - 13 = 38
r/10 = (-6)
Here we multiply both sides by 10:
r = (-6)*10 = -60
a + (-12) = 45
Here we add 12 in both sides:
a = 45 + 12 = 57
Then we conclude that the solution for the given algebraic expressions are:
- J = -5
- s = -106
- t = 38
- r = -60
- a = 57
