Answer:
25.50
Step-by-step explanation:
-5 notebooks $2 each
-4 pencils $1.50 each
-2 packs of markers $3.75 each
5(2)+4(1.50)+2(3.75)
$23.5
23.5 times 8.5/100
1.9975
plus 23.5
25.4975
rounded to 25.50
Imagine there are 8 spots on the shelf. Replace the volumes one by one.
The first volume to be replaced could go in any one of the eight spots.
The second volume to be replaced could then go in any one of the seven remaining spots.
The third volume to be replaced could then go in any one of the six remaining spots.
etc
So the total number of ways the eight volumes could be replaced
= 8!
= 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 40,320

It's simple.
Step-by-step explanation:
now since you solved some of it, 18 + 12 = 30 An expression that is equivalent to this sum is 30.
Answer:25 months
Step-by-step explanation: Let's make the equations first,
Plan A: 70x Plan B: 50x+500
Now we make it into an equivalent equation:
70x=50x+500
Then we solve:
70x=50x+500
-50x -50x
20x=500
÷20 ÷20
x=25
To check if it's correct, we just plug it in:
70(25)=50(25)+500
1750=1750
