Answer:
x = 100º
y = 100º
Step-by-step explanation:
180º = 80º+y
180º-80º = 80º-80º+y
100º = y
x and y are equal so x is also 100º

5x + 3 = 3x + 9 what is the value of x
Answers
Answer:
x = 3
Step-by-step explanation:
5x + 3 = 3x + 9
subtract 3 on both sides (cancels out 3) (inverse operation)
5x = 3x + 6
subtract 3x on both sides (cancels out 3x) (inverse operation)
2x = 6
divide both sides by 2 (isolates x) (simplifies)
x = 3

John is on vacation and forgot his video camera. He found a camera shop that rents the cameras. They charge a one-time cleaning fee of $45 and the per day rental charge is $23. If his final bill is $229, how many days did John rent the video camera? Write and solve an equation for John's camera rental.
Answers
Given:
One-time cleaning fee = $45
Per day rental charge = $23
Final bill = $229
To find:
The number of days for which John takes video camera on rent.
Solution:
Let the number of days be d.
Rental charge for one day = $23
Rental charge for d days = $23d
Total charges = One-time cleaning fee + Rental charge for d days
[tex]Total=45+23d[/tex]
Final bill is $229. So,
[tex]45+23d=229[/tex]
Subtract 45 from both sides.
[tex]45+23d-45=229-45[/tex]
[tex]23d=184[/tex]
Divide both sides by 23.
[tex]d=\dfrac{184}{23}[/tex]
[tex]d=8[/tex]
Therefore, the required number of days is 8.

line I is the perpendicular bisector of MN. find m
Answers
Answer:
m = 68
Step-by-step explanation:
MN bisects it or splits it in half so we know N = M, which we could also write as 8x-12 = 5x+18 because they give us those equations
once you have 8x-12 = 5x+18 you can subtract 5x from both sides, so you will get 3x-12 = 18, then you can add 12 to both sides and you will get 3x = 30. Once you have narrowed down to this you can divide three by both sides making x = 10
Now that we know x =10 we can insert it into the equation
5(10) + 18 = m
50 + 18 = m
m = 68

Answer:
LOOK BELOW !!!
Step-by-step explanation:
[tex]7y = 8x - 14[/tex]
get rid of the Y and put in a 6
[tex]7(6) = 8x - 14[/tex]
[tex]7 \times 6 = 42[/tex]
[tex]42 = 8x - 14[/tex]
we need to get rid of the negative 14 so its only 8x.
to get rid of 14 on one side you add it to the other
[tex]42 + 14 = 56[/tex]
[tex]56 = 8x[/tex]
to get X by itself have to divide 8 by both sides
[tex]56 + \div 8 = 7[/tex]
[tex]8x \div 8 = x[/tex]
[tex]x = 7[/tex]

The equation s =square root 30fd can be used to find the car's speed s in mph given the length d in feet of a skid mark and the friction factor f of the road. Police measured a skid mark of 90 feet on a dry concrete road. If the speed limit is 35mph, was the car speeding? Explain
Answers
Answer:
Yes, the car was speeding the speed limit.
Step-by-step explanation:
The given equation to find the car's speed, s (in mph), is
[tex]s=\sqrt{30fd}[/tex]
where, d is the length of the skid and f is the friction factor.
Police measured a skid mark of 90 feet, so d=90
As the road is dry and of concrete, therefore the friction factor, f=0.8.
So, the speed of the car
[tex]s=\sqrt{30\times0.8\times90} = 46.48[/tex] mph
The speed of the car is 46.48 mph which is more than the speed limit of 35 mph.
Hence, the car was speeding the speed limit.
