Answer:
j
Step-by-step explanation:
Answer with explanation:
The given expression is
=ab+cd+ef+gh
The meaning of expression is equal to terms which contains variables and constants and operation between them is Addition, Subtraction, Multiplication and Division.
→The expression consists of four terms which are, ab, cd, ef, and gh.
→Each term contains
Two factors.
Answer:
Shirt: $2.25. and Pants: $1.50
Step-by-step explanation:
Set up equations with shirts as s and pants as p.
Subtract them as there are two variables and two equations:
- -2p=-3
- Make positive, 2p=3
- Divide, p=1.5
To find s:
- 3s+7(1.5)=3s+10.5=17.25, so 3s=6.75 and s=2.25
- 3s+9(1.5)=3s+13.5=20.25, so 3s=6.75 and s=2.25
Using the Fundamental Counting Theorem, there are 20 possibilities for their big night out.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
For this problem, we have that:
- There are 5 restaurants, hence .
- There are 4 stores, hence .
The number of possibilities is given by:
N = 5 x 4 = 20.
