13.50 per set
+.45 per day value
she got 20 sets
5 days after would be
13.50 ×20=270
value of 20 sets at 13.50 a set on day one was 270.00
.45×20=9.00
the 20 sets gain 9 dollars a day
9×5=45
9 dollars a day times 5 days is 45 dollars
45+270=315

Answer:
x = 6
Step-by-step explanation:
44 + 3x = 5x + 2x + 20 transfer like terms to the same side of the equation with the opposite sign:
44 - 20 = 5x + 2x - 3x add/subtract like terms
24 = 4x divide both side by 4
6 = x
Answer:
y = −1/3x+17/3
Step-by-step explanation:
The line segment has slope -1/3. This means that any line perpendicular to it will have a slope of 3 (negative reciprocal)
Any line that bisects the line segment will pass through its midpoint. The midpoint is (5,4)
Midpoint formula: 
So perpendicular bisector of this line is simply a line with slope −1/3 that passes through point (5, 4)
y - 4 = -1/3 (x-5)=
y = −1/3x+17/3
Answer:
Fraction: 1/ 5 n= 7
Step-by-step explanation:
To find n first you cross multiply : 2/ 10 * n / 35
= So we multiply 10 and n ( answer = 10n)
= Then 2 and 35 ( multiply) ( answer = 70)
Now algebra
70 = 10n
Divide both sides by 10
10n / 10 = 70 / 10
n = 7
The fraction becomes 7 / 35
When this is simplified the answer is 1 / 5
To simplify you divide the numerator and denominator of the fraction by 25 ( GCF )
