Answer:
420
Step-by-step explanation:
15%= 0.15
2800*0.15= 420
Answer:
it's 7500
Step-by-step explanation:
20% of 7500 is 1500. General tip, commission is usually 25%
Just graph them. put the x number on the x-line and the y numbers on the y-line
Given:
Perimeter of a parallelogram = 64 cm
Length = 3 times larger than the width
To find:
The length of the parallelogram.
Solution:
We know that, the perimeter of the parallelogram is:
Where, l is length and w is width of the parallelogram.
We have, l = 3w and P=64.
So,
Divide both sides by 8.
Now,
Therefore, the length of the parallelogram is 24 cm.
Answer:
3x+4x=7x
Step-by-step explanation:
basically 3x+4x means 3*x+4*x
thus, we can take x out as a common factor of both
x(3+4)= x*7=7x
or
you can sum the variables with the same element (x is our element in here)
thus,
3x+4x=7x
if it would be 3x+4y you cannot sum them since the elements are different (x and y)
