Answer:
Matched pairs design
Step-by-step explanation:
Looking at the options;
-It's not a completely randomized design because a randomized design will assign all individuals to a group which in this case it doesn't.
- It's not a randomized block design because randomized block design will group the subjects in question into 2 or more blocks which have a common characteristic and will then randomly assign subjects in each of the blocks.
-It's a matched pair because every individual/subject undergoes measurements both before and after being treated with the drugs.
Thus, the correct option is matched pairs design.
The x coordinates will stay the same. the y coordinates will be opposite.
He needs to give each of his friends 3 cards each
A negative plus a negative is a negative. so the answer would be -13
5x-10=2x+5
We simplify the equation to the form, which is simple to understand
5x-10=2x+5
We move all terms containing x to the left and all other terms to the right.
+5x-2x=+5+10
We simplify left and right side of the equation.
+3x=+15
We divide both sides of the equation by 3 to get x.
x=5
