Answer:
I think its 25 (proceed with caution)
Step-by-step explanation:
15×4=60 so basically 6.25×4=25
6.25 = 6 1/4
Answer:
Let p be the number of pens and let n be the number of notebooks.
4 notebooks + 3 pens cost $96 so 4n + 3p = 96
2 notebooks + 2 pens cost $54 so 2n + 2p = 54
We find n and p by solving the system of linear equations:
4n + 3p = 96
2n + 2p = 54
4n + 3p = 96
4n + 4p = 108 (we multiply this by 2 to cancel out 4n in both equations)
We then subtract the two equations:
(4n + 3p) - (4n + 4p) = 96 - 108
-p = -12
p = 12
So, a pen costs 12 dollars. We can use p to find n. We substitute 12 for p in one of our earlier equations:
2n + 2p = 54
2n + 2(12) = 54
2n + 24 = 54
2n = 30
n = 15
So, a notebook costs 15 dollars and a pen costs 12. Now, we need to find the cost of 8 notebooks and 7 pens:
8n + 7p = ?
8(15) + 7(12) = ?
120 + 84 = 204.
Thus, 8 notebooks and 7 pens cost 204 dollars (why is it so expensive lol).
Answer:
The answer is 0 or No Slope
Step-by-step explanation:
This type of line in the graph is called no slope its means it doesn't rise over time
Pls mark me as brainliest
Answer:
the longest side is 25
Step-by-step explanation:
the equation would be x+ x+1 + 7 for the 3 sides of the triangle
x + (x+1) + 7=56
combine like terms
2x+8 = 56
subtract 8 from each side
2x = 48
divide by 2
x = 24
the sides are
x=24
x+1 = 25
7
the longest side is 25
(3/36)
a. divide both by the same number.
b. 3 ÷ 3 = 1, and 36 ÷ 3 = 12
c. The simplest form of 3/36 is 1/12.
(25/30)
a. 25 and 30 are both divisible by 5.
b. 25 ÷ 5 = 5, and 30 ÷ 5 = 6
c. The simplest form of 25/30 is 5/6.
