ANSWER
EXPLANATION
The given fractions are:
We factor to obtain:
We cancel the common factors to get:
We multiply the numerators and also multiply the denominators to get:
Therefore the two fractions simplifies to
Answer:
slope is equal to rise (going up or down on graph) over run (going left or right)
Step-by-step explanation:
1 = - 
2= 
= 2
3. 
4. -
5. 
= 
6. -
= - 
As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.
For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.
So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.
When you are told to estimate, you should be able to do the problem in your head.
8 7/12 is close to 8 1/2
4 7/8 is very nearly 5
4/10 is very nearly 1/2
8 1/2 - 5 - 1/2 First of all you can take the 1/2 away from 8 1/2
8 1/2 - 1/2 = 8
Now take away the 5
8 - 5 = 3
So the answer is very nearly
3 <<<<< answer.
Just for fun, I'll get the exact answer. Don't hand this one in. It is 3 37/120
You learn to estimate because you are trying to guess whether or not you've entered everything correctly into your calculator. When writing a test, this is a very handy skill to have developed.
You would add the area of the square with the area of the triangle.
Square: length x width
In your case, it would be 100in²
Triangle: length x height x 1/2 (or length x width divided by 2)
16-10 would be 6 (height) 10-6= 4 (length)
6 x 4 x .5 = 12in²
100in²+12in²=112in²
The area is 112in²
