Answer:
4x-13
Step-by-step explanation:
Let the number is x.
We know that triple of a number is 3 times that number i.e. 3x
The difference between triple the number and thirteen 3x-13
Now, we need to add a number to the difference between triple the number and thirteen. So, the expression can be written as :
x+3x-13 = 4x-13
Hence, the expression is (4x-13).
Answer:
0
Step-by-step explanation:
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope ----><em><u> m= y2-y1/x2-x1</u></em>
Answer:
48
Step-by-step explanation:
L = D + 28
⅓L = ⅘D
Solve the system of equations using elimination or substitution. Using substitution:
⅓L = ⅘(L − 28)
Multiply both sides by 15:
5L = 12(L − 28)
Distribute:
5L = 12L − 336
Combine like terms:
336 = 7L
Divide:
L = 48
