What is the value of the x ? x + x + x = 56
Answers
Hey there!
ORIGINAL EQUATION
x + x + x = 56
CONVERT/COMBINE the LIKE TERMS
1x + 1x + 1x = 56
2x + 1x = 56
NEW EQUATION
3x = 56
DIVIDE 3 to BOTH SIDES
3x/3 = 56/3
SIMPLIFY IT by canceling out 3/3 because it give you 1 & KEEP 56/3 because help solve for the x-value (it also give you the x-value result)
x = 56/3
x = 18.666667
x = 18 2/3
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE ALL EQUIVALENT TO EACH OTHER

A bracelet that regularly sells for $44 is on sale for 15% off. Find the sale price of the bracelet. Use dollar signs with your answer. *
Answers
Answer:
The answer would be $37.40
Step-by-step explanation:
The sale price would be the current price which is 44 - 15% of itself.
It is 15 percent off, so 44 x 0.85 would be the equation, since the now price is 85 percent of the original price.
44 x 0.85 = 37.40
