Answer:
Step-by-step explanation:
you can solve for the fractions first, but you have to give them a common denominator
which is in simplest form
then solve for the whole numbers
3-2=1
therefore, the answer is
Answer:
(9, <u>81</u>) (<u>8</u>, 71)
Step-by-step explanation:
My explanation is in the picture. All I did was replace the known variable with the proper letter!
|2x + y - 3z|
Plug in the values
|-4 + 10 - 9|
= |-3|
= 3
Answer:
A = 100
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A = (a + b)
Now, substitute the values of the height and the bases:
A = (10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100
A rational number is a number that can be written into a fraction. pi, some square roots, e, etc., are irrational numbers(numbers that cannot be written into a fraction).
