7.5 the shipping fee
1.75 the shipping fee
1.75 the cost per video game
pls guys answer it
Answer:
The rate of change is [tex]\frac{7}{4}[/tex] or 1.75. That shows that the cost per video game is $1.75
Step-by-step explanation:
The change in y over change of x or slope can be calculated using the equation:
[tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] so take the last two points: (10, 25) and (15, 33.75).
33.75-25=8.75
15-10=5
8.75/5=1.75 (7/4)
x=video games
y=total cost
Since slope is change in y (cost) per change of x (video games), the answer is:
1.75 cost per video game

Answer:
x = 13
Step-by-step explanation:
x and 167 are a linear pair, x plus 167 will equal 180
x + 167 = 180
x = 180 - 167
x = 13
To check: x + x + 167 + 167 = 360
x = 13
13 + 13 + 167 + 167 = 360
26 + 167 + 167 = 360
26 + 334 = 360
360 = 360
Answer:
[tex]x = 13[/tex]
Step-by-step explanation:
[tex]x + 167 = 180(linear \: pair) \\ x = 180 - 167 \\ x = 13[/tex]

find exterior angle
Answer:
∡3 = 142°
Step-by-step explanation:
28° + 10° + ∡3 = 180° (Sum of angles in a triangle)
38° + ∡3 = 180°
∡3 = 180° - 38°
∡3 = 142°
Alternate method:
38° + ∡3 = 180° (Sum of angles on a straight line)
∡3 = 180° - 38°
∡3 = 142°
Answer:
38 degree + 180 degree = [ sum of angle on a straight line]
3= 180 degree - 38 degree
3= 142 degree.

What is the increase of 15837.77 by 8.5
Answer:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
8.5% = 8.5/100 = 8.5 ÷ 100 = 0.085.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 8.5% of its value.
Percentage increase = 8.5% × 15,837.77
New value =
15,837.77 + Percentage increase =
15,837.77 + (8.5% × 15,837.77) =
15,837.77 + 8.5% × 15,837.77 =
(1 + 8.5%) × 15,837.77 =
(100% + 8.5%) × 15,837.77 =
108.5% × 15,837.77 =
108.5 ÷ 100 × 15,837.77 =
108.5 × 15,837.77 ÷ 100 =
1,718,398.045 ÷ 100 =
17,183.98045 ≈
17,183.98
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 15,837.77 =
17,183.98045 - 15,837.77 =
1,346.21045 ≈
1,346.21
Proof.
Calculate percentage increase:
Percentage increase =
8.5% × 15,837.77 =
8.5 ÷ 100 × 15,837.77 =
8.5 × 15,837.77 ÷ 100 =
134,621.045 ÷ 100 =
1,346.21045 ≈
1,346.21

A car costs $3,500 and costs $4 in gas to drive fifteen miles. If another car costs $4,500 but only need $2 in gas to drive fifteen miles, after how many miles of driving would be the total cost of driving both cars be equal?
Answer:
500 miles
Step-by-step explanation:
Step one:
A car costs $3,500 and costs $4 in gas to drive fifteen miles
let the total cost be y and let the number of miles be x
y= 3500+4x-----------1
If another car costs $4,500 but only need $2 in gas to drive fifteen miles,
let the total cost be y and let the number of miles be x
y= 4500+2x----------------2
Step two:
Equate the two expressions for the total cost
3500+4x=4500+2x
solve for x
4x-2x=4500-3500
2x= 1000
divide both sides by 2
x= 1000/2
x= 500 miles
