8p + 3q - 18 when p = 1/2 and q = 7
You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.
Rewrite your expression to include the values of p and q plugged in. Your expression should look like:
8(1/2) + 3(7) - 18
According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:
4 + 21 - 18
According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.
4 + 21 = 25
25 - 18 = 7
Your answer is 7.
3 tens
7 ones
This is the same as 30+7 which is 37
Answer:
D
Step-by-step explanation:
In scientific notation, the number that is being multiplied by the power of ten must be greater than or equal to 1 and less than 10. This eliminates options B, C, and E. The rest of the options are all 5.79 times something. To find that something, we can do 5,790,000 / 5.79 = 1000000 = 10⁶. This means that the answer is D.
Answer:
1) If Sam is an expert sailor then she will be allowed on Signe's racing boat.
2) If Sam is not allowed on Signe's racing boat, then she is not an expert sailor.
Step-by-step explanation:
- The contrapositive statement of if P → Q is if ~Q→~P.
In this case we have: If Sam is an expert sailor then she will be allowed on Signe's racing boat.
P = Sam is an expert sailor
Q = Sam will be allowed on Signe's racing boat.
To write the contrapositive statement we're going to say if ~Q→ ~P
If Sam is not allowed on Signe's racing boat, then she is not an expert sailor.
