2(4 + 2x) ≥ 5x + 5? please help
1 answer:
2(4 + 2x) ≥ 5x + 5
First, we will need to expand our problem. Expanding is basically removing the parentheses. To do this, we will look at the first part of the problem to begin with. 2(4 + 2x). Since parentheses usually mean multiplication, we can start with 2(4). So, 2 × 4 = 8. We'll do the same thing with 2(2), 2 × 2 = 4.
Second, our next step is to subtract 4 from each side. We are trying to get the variable (x) on one side of the problem by itself.
Third, we can now simplify (5x) + 5 - (4). I put parentheses around what we are going to focus on. Subtract 5x - 4 to get 1, which can be put as the variable (x). Now we have, x + 5.
Fourth, let's subtract 5 from each side now. This will set up 8 - 5 which equals 3.
Fifth, we can switch sides now to get the result of this problem.

Answer:
80%.
Step-by-step explanation:
Given the following probabilities:
- P(Micheal Being admitted to French), P(F)=50%
- P(Micheal Being admitted to Spanish), P(S)=50%
In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:
- P(Micheal Being admitted to BOTH French and Spanish),
We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).
Probability of either A OR B =
From Probability Theory:
The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.
