Answer:
-1, 0, 1, 2, 3
Step-by-step explanation:
To answer this you have to understand 2 main things
These are: the symbols and what an integer is.
An integer is simply a whole number. For example: 1, 10, 3 etc.
The symbols, <= (first symbol) and < (second symbol) are very important. These tell us the range X is in.
<= means less than or equal to.
< means less than.
So we can write: -1 is less than or equal to x and x is less than 4.
If we follow this and also keep in mind we only want whole numbers then we can see the lowest X can be is -1 and the highest it can be is 3 since it has to be less than 4.
Then it is also everything inbetween them which is:
-1, 0, 1, 2, 3
Answer:
2000 times
Step-by-step explanation:
Given
Sara:
Sam:
To determine the number of times, the mass of Saturn is greater than the mass of Mercury, we simply do the following:
Using Sara's measurement; this gives:
Apply law of indices
Approximate
Answer:
-7
Step-by-step explanation:
It just means put 1 for x so -3-4=-7
X + 5x - 13 = 140
6x - 13 = 140
6x = 153
x = 25.5
5(25.5) -13 = 114.5
CHECK: 25.5 + 114.5 = 140
-(x-2) = x + 2
- x + 2 = x + 2
2x = 0
x = 0
