Let notebooks be x and let pencils be y
4x+9y=8.25 (equation 1)
7x+14y=14.00 (equation 2)
Multiply equation 1 by 7
So that you get 28x+63y=57.75
Multiply equation 2 by 4
So that you get 28x+56y=56.00
28x+63y=57.75 -
28x+56y=56.00
-----------------------
7y=1.75
Divide both sides by 7
1.75/7 is 0.25
So, now we know that one pencil costs 0.25 cents
Sub this y value into equation one
4x+9(0.25)=8.25
4x+2.25=8.25
Move 2.25 to the other side as a negative number
4x= 6
Divide both sides by 4
6/4 is $1.50
So, one pencil is equal to 0.25 cents and one notebook is equal to $1.50
Answer:
40
Step-by-step explanation:
the tens value is the 2 value from the left of a decimal point.
Examples: 32 67.4 2345 904
In your case, the tens value is 4
We need to look at the ones value to see if we need to round up or down
Because the ones value, 2, is less than 5, we keep the tens value, so it's 40
Answer:
a ) If r ⇒ p
If q ⇒ p
r ∪ q
If r∪p ⇒ ¬ r
∴ s
b) The argument is invalid
Step-by-step explanation:
The argument is invalid because we do not with precision if b), because we do not have enough information about it, and this is because the previous sentences does not mention information about the donkey. We cannot infer something when we do not have enough information.
We will see that there are 156,000 different combinations, so the correct option is C.
<h3>How many possibilities are there? </h3>
First, we need to find the selections, here we have:
- First letter.
- Second letter.
- Third letter.
- Number.
Now we need to find the number of options for each of these selections.
- First letter. (26 options)
- Second letter. (25 options, because we can't repeat letters)
- Third letter. (24 options)
- Number. (10 options).
We assumed that the number can be any integer from 0 to 9.
The total number of possibilities is equal to the product between the numbers of options, we will have:
P = 26*25*24*10 = 156,000
So, the correct option is C.
