Answer:
the answer is about 8 cuz the answer shows 7.12 if you divide mentally
Answer:
a: K = 2s
K + s = 42
b: 2s + s = 42
K = 28
s = 14
Step-by-step explanation:
1. Come up with equations based on the information given.
K = Kim
s = sister
Kim is twice of her sister -> K = 2s
When you add Kim's age to her sister's age, you get 42 -> K + s = 42
2. Substitue for K to find out the value of s
K = 2s
2s + s = 42
3. Solve for s
s = 42/3
s= 14
4. Solve for K
K = 2s
K = 2*14
K = 28
The answer is nucleus. The nucleus acts as the control center of a cell.
Answer:
It is angle 4 because they make 90 degrees together. This is if there are choices for the problem.
It would be ∠4
Let's try this.
First, we have the absolute value of -4(-2)-8, or the absolute value of 8-8, so 0.
Let's forget about that, now. It's 0, it adds no value. Let's not worry about it.
For the next, we see the absolute value of -1-(-2)^2
Or:
-1-4, or -5.
Next is 2(-2)^2, or 2(4) = 8.
Therefore, we have -5+8 =3.
