Answer:
6.79
Step-by-step explanation:
First of all, you will have to know how much is 3% of 7 in order to decrease it by that amount.
7 x 0.03 = 0.21

Answer:
273
Step-by-step explanation:
Answer:
Let x represent one of the equal length sides making the third side which is 3 inches shorter than each of the other two equal to:
Third piece = x
−
3
. Knowing that the whole board is 10 feet, in inches it is:
10 feet × 12 inches
/ 1 foot = 120 inches
To find the length of the pieces, add them and equate it to the legth of the board in inches as shown below:
x + x + x − 3 = 120 + 3
3
x
/3 = 123
/3
x = 41 inches
Third piece = x − 3 =
41 − 3
= 38 inches
