Answer:
Yes, cells are living, because they make up living things, and can do what most living things are able to, like reproduce.
(3 x 3 - 6) = ?
First, multiply 3 x 3, which = 9
(9 - 6)
Then subtract 9 by 6, giving you 3.
So, :
(3 x 3 - 6) = 3
Answer:
Step-by-step explanation:
That means that the number must end in 2 or 8 to be divisible by 2.
Because the number must be between 7000 and 8000 the only number it can start with is 7
With those clues in mind, we can write
1 * 2 * 1 * 2. It doesn't say if we can use a number more than once. I am assuming not. We should get 4
7 2 5 8
7 5 2 8
7 5 8 2
7 8 5 2
If you're looking for the solution to the system of equations, here's how we solve using substitution
We know that y = x - 1, so we can plug that into the first equation giving
2x - 3(x-1) = -1
Now distribute the 3 giving 2x - 3x + 3 = -1. After combining like terms we get -x + 3 = -1. Now subtract 3 from both sides, -x = -4, and multiply both sides by -1 to make x positive. x = 4
Now we can plug that into the second equation to get y
y = x - 1, and we know that x = 4, so y = 4 - 1, y = 3. The solution is (4, 3)
Hello there! :)
The first step is to use the Distributive Property.
It states that
a(b+c)=ab+ac
Let's distribute 3, using this property:
3(x-6)=3x-18
Now, our inequality looks like so:
12+x≤3x-18
The next step is to move the variables to the left, using the opposite operation:
12+x-3x≤-18
12-2x≤-18
Now, move all the numbers to the right, using the opposite operation:
-2x≤-18-12
-2x≤-30
Divide both sides by -2 to isolate x.
Remember that when we divide by a negative variable, we change the inequality sign:
x≥15
Therefore, x≥15
