We have two congruent trapezoids.
The formula of an area of a trapezoid:

We have:

Substitute:

Answer:

The way you work this out is by thinking about the odds of each singular event, then finding the overall odds based on the individual odds.
The number of different books Mrs. Reid can choose is 9, so the first number is 9.
Mrs. Reid has picked one book so far, so now she has (1 - 9) = 8 books to choose from.
The of different books Mrs. Reid can choose now is 8, so your second number is 8.
Mrs. Reid has picked 2 book thus far, so now there are (2 - 9) = 7 books to choose from.
The of different books Mrs. Reid can choose now is 7, so your second number is
7.
To get the total number of different choices, multiply all the singular events together:
(-1,2) is a solution
y>x
2>-1 is correct
in this case yes
x+y≥x
-1+2≥-1
1≥-1 is correct: Yes
in this case no
x+y≥y
1≥2
is not correct. No
Answer:
The width of the field is 3.535353535m
Step-by-step explanation:
350÷99=3.535353535
Proof: 99×3.535353535=350
The two equations would yield no solution if they are dependent. That means that both equations are equivalent. You can determine this by manipulating the equations through simplification. For example, a dependent equation would be:
3x - 4y = 2
3x/2 - 2y = 1
Another dependent equation is when you multiply the whole equation with a number, say 3.
(3x - 4y = 2)3
9x - 12y = 6
