(8a + 8) + (5a – 6).
8a+8+5a−6
=8a+8+5a+−6
Combine Like Terms=8a+8+5a+−6
=(8a+5a)+(8+−6)
=13a+2
=> (8a + 8) + (5a – 6)
=> (8a + 5a) + (8 – 6) [Combine like terms]

Suppose you observe a star orbiting the galactic center at a speed of 1300 km/skm/s in a circular orbit with a radius of 18 light-days. Calculate the mass of the object that the star is orbiting.
Answer: 1.1818^37 kg
Step-by-step explanation:
Given that:
Orbit speed = 1300 km/s
Radius (r) = 18 light days
Mass of object the star is orbiting :
Using the relation :
M = rv² / G
Where ; r = Radius in m ; v = velocity in m/s
G = 6.67 * 10^-11 = gravitational constant
18 light days in meters = 4.662 * 10^14 m
v = 1300km/s to m/s
v = (1300 * 1000)m /s = 1300000 m/s = 1.3 * 10^6 m/s
Hence ;
M = (4.662 * 10^14 * (1.3 * 10^6)^2 / (2/3) * 10^-10
M = (4.662 * 10^14) * (1.69 * 10^12) / (2/3) *10^-10
M = (7.87878 * 10^26) / 6.67 * 10^-11
= 1.1818^37 kg

correctly factor the expression 15a-6b+36 using the greatest common factors
Answer:
3 ( 5a - 2b + 12)
Step-by-step explanation:
15 = 3 * 5
6 = 2 * 3
36 = 2 * 2 * 3 * 3
GCF = 3
15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)
= 3 ( 5a - 2b + 12)
Answer:
3 ( 5a - 2b + 12)
Step-by-step explanation:
15 = 3 * 5
6 = 2 * 3
36 = 2 * 2 * 3 * 3
GCF = 3
15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)
= 3 ( 5a - 2b + 12)

What mathematical formula do you use for the following question. A rectangle whose perimeter is 104 feet has a length that is 12 feet longer than its width what is the area of the rectangle. The answer is 640 square feet 20 feet wide by 32 feet long.
Answer:
Width = 20 inches and Length = 32 inches
Area of rectangle = 640 feet²
Step-by-step explanation:
Perimeter of rectangle = 104 feet
Let width of rectangle = x
Length of rectangle = x+12
We need to find area of rectangle.
First we need to find value of x
The formula used to calculate perimeter of rectangle is: [tex]Perimeter= 2(Length+Width)[/tex]
Putting values and finding x
[tex]Perimeter= 2(Length+Width)\\104 = 2(x+12+x)\\104=2(2x+12)\\104=4x+24\\4x=104-24\\4x=80\\x=\frac{80}{4}\\x=20[/tex]
So, Value of x= 20
So, Width x= 20 inches
Length = x+12 = 20+12 = 32 inches
So, Width = 20 inches and Length = 32 inches
Now finding Area
The formula used is: [tex]Area=Length\times Width[/tex]
Putting values and finding area
[tex]Area=Length\times Width\\Area=20\times 32\\Area=640 \ feet^2[/tex]
Area of rectangle = 640 feet²
Chi has $11:30 in dimes and quarters. The number of dimes is three more
than three times the number of quarters. How many of each are there?
DO NOT COPY AND PASTE. THE ANSWER IS 63 DIMES AND 20 QUARTERS. HOW DO I GET THIS.
Answer:
To solve this question, we first have to know that we are trying to assemble
and solve equations with two variables: x
and y.
Assuming x
is the number of dimes and y
is the number of quarters, we
can assemble the equations.
since the number of dimes is 3 more than three times the number of quarters,
we get x=3y+3.
Additionally, multiplying the number of dimes by 0.1 and the number of
quarters by 0.25,
we get the total value of x
and y
which appears by this
equation 0.1x+0.25y=11.30
.
Substituting the value of x
in the second equation, we get 0.1(3y+3)+
0.25y=11.30
.
Solving this equation, we get that the value of x,
we get x=3×20+3=
Using the first equation to get the value of x,
we get x=3×20+3=
60+3=63
dimes.

A caterer charges $275 for 15 people and $425 for 25 people. The cost, y, is a linear function of the number of x people. Write an equation in slope-intercept form for this situation. *
Answer:
The equation of the given situation is y = 15x + 50
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope b is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ A caterer charges $275 for 15 people
∵ A caterer charges $425 for 25 people
∵ x represents the number of people
∵ y represents the cost
∴ (x1, y1) = (15, 275)
∴ (x2, y2) = (25, 425)
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{425-275}{25-15}=\frac{150}{10}[/tex]
∴ m = 15
→ Substitute it in the form of the equation above
∴ y = 15x + b
→ To find b substitute x by 15 and y by 275
∵ 275 = 15(15) + b
∴ 275 = 225 + b
→ Subtract 225 from both sides
∴ 275 - 225 = 225 - 225 + b
∴ 50 = b
→ Substitute it in the equation
∴ y = 15x + 50
∴ The equation of the given situation is y = 15x + 50

The expressions to represent the costs of each club is $10 + ($15 * m)
Let's begin by writing expressions for the costs of each club:
Multiplayer Madness:
Joining Fee: $50 (one-time payment)
Monthly Fee: $0 (since it's not mentioned, we assume there's no additional monthly fee)
The total cost for Sharleen to join Multiplayer Madness would be the joining fee only, which is $50.
Games Galore:
Joining Fee: $10 (one-time payment)
Monthly Fee: $15 (recurring monthly charge)
The total cost for Sharleen to join Games Galore would be the joining fee plus the cumulative monthly fees over time. Let's represent the total cost of Games Galore as a function of the number of months (m) Sharleen stays in the club:
Total Cost of Games Galore = Joining Fee + (Monthly Fee * Number of Months)
Total Cost of Games Galore = $10 + ($15 * m)

Answer:
∠CDF = 54
Step-by-step explanation:
In ΔAEB,
AE ≅ AB
∠ABE = ∠E = x {Angles opposite to equal sides are equal}
∠EAB + ∠E +∠ABE = 180 {angle sum property of triangle}
26 + x + x = 180
26 + 2x = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77
∠ABE = ∠E = 77
In quadrilateral AECF
∠A + ∠E + ∠C + ∠F = 360
90 + 77 + ∠C + 90 = 360
∠C + 257 = 360
∠C = 360 - 257
∠C = 103
∠FCD + ∠BCD = ∠C
∠FCD + 67 = 103
∠FCD = 103 - 67
∠FCD = 36
ΔFCD,
∠FCD + ∠CDF + ∠CFD = 180
36 + ∠CDF + 90 = 180
∠CDF + 126 = 180
∠CDF = 180 - 126
∠CDF = 54
