Let the unknown number be x.
6x + 8 = 9x
-3x = -8
x = 8/3
The number is 8/3 or 2 2/3
$4/8 juice boxes= $0.50 per juice box
Final answer: $0.50 per joice box
N:7=x remainder 2
⇒ n= 7*x +2
4n= 4*(7x+2)=28x+8=28x+7+1=7*(4x+1)+1
⇒ the remainder is 1
Answer:
$7.67
Step-by-step explanation:
So if 8 pens cost $4.72, one pen would cost $0.59. 0.59 x 13 will be equal to 7.67.
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
