We can say that because 3 times 9, which would equal 27, could be the same as 4*9, which would be 36. So Pat needs 36 pints of green paint. Down below is a tape diagram so you can see what it is.
Answer:
-6c + 7
Step-by-step explanation:
To simplify this expression, you must add like terms. Because 3c and -9c both have the same variable (c), they are like terms.
3c + (-9c) = -6c
The 7 stays the same, so the simplified expression is -6c + 7.
Hope this helped :)
Answer:

Step-by-step explanation:
We want to write an integer expresion to represents the verbal expresion:
"the opposite of the absolute value of negative seven"
The absolute value of negative seven is written as:

When we simplify this, we get 7.
This integer is positive.
The opposite of positive seven is negative seven.
Therefore the required integer expresion for "the opposite of the absolute value of negative seven" is 
For me personally i can work nearly any equation with a calculator. definitely a good choice <span />
Given:
Positions of two artifacts are at points (1, 4) and (5, 2).
To find:
The distance between these two artifacts.
Solution:
Distance formula: The distance between two points is

Using distance formula, the distance between two points (1, 4) and (5, 2) is





Round to the nearest tenth of a unit.

Therefore, the distance between two artifacts is 4.5 units.
