Hello!
[tex]\large\boxed{x = 21}[/tex]
[tex]\frac{-x}{3} + 2 = -5[/tex]
Begin isolating for x by subtracting 2 from both sides:
[tex]\frac{-x}{3} + 2 - 2 = -5 - 2\\\\\frac{-x}{3} = -7[/tex]
Further simplify by multiplying both sides by 3:
[tex]\frac{-x}{3} * 3= -7 * 3\\\\-x= -21[/tex]
Multiply both sides by -1 to cancel out the -x:
[tex]-x(-1) = -21(-1)\\\\x = 21[/tex]

Leo made a 59, 84, 61, and an 81 on the first four tests. What score
would he have to make on the 5th test in order to make at least an 85
in the course?
Answer:
71
Step-by-step explanation:
59 add 84 add 61 add 81 is 285
285 divided by (how many test scores) 4 is 71.25
I then rounded the number to 71. So leo would get 71. This is called mean. The mean is basically adding all the numbers then dividing it by how many there were of numbers. Mean tells you the average. So I'm pretty sure it's 71.

Sound travels through air at about 344 meters per seconds when the temp. is 20 degrees c. If Enrique lives 2 kilometres from the fire station and it takes 5 seconds of the fire station siren to reach him, how can you prove indirectly that it's not 20 degrees Celsius when Enrique hears the siren?
The temperature at the time the siren sounded is not 20 degrees c because, the speed of the siren sound is 400 meters per second, contrary to the speed of sound at 20 degrees c, 344 meters per seconds.
According to the question:
At 20 degrees c, sound travels throughout air at about 344 meters per seconds.However, Enrique's house is 2 kilometres from the station and it takes 5 seconds for the fire station siren to reach him.
In essence, the speed of the siren sound is;
Speed = 2,000/5 = 400 meters per second.
Ultimately, since the speed of the siren sound is 400 meters per second, contrary to the speed of sound at 20 degrees c, 344 meters per seconds.
We can conclude that the temperature is not 20 degrees c.

show all your steps to your answer. 9x +6y = 78
3х - 6y = -30
Answer:
x=4
Step-by-step explanation:
You put 9x+6y=78 over 3x-6y=-30. Then, you are going to add the two equations. So, you are going to do 9x+3x, 6y-6y (since the second 6 is negative, it ends up subtracting), and 78-30. You will end up canceling the 6y's, and end up with 12x=48. Then, you will divide 48 by 12, and get x=4. Hope this helped:)

Answer:
The answer is 7.
Explanation:
The answer is 7, because [tex]\frac{7}{14} -\frac{4}{14} =\frac{3}{14}[/tex]. If the fractions have common denominators (14) then just subtract the numerators like a regular subtraction problem, and 7 minus 4 equals 3, so 7 is the answer.

Answer:
10) 57.611) 27.3 12) 12.75 13) 1014) 14 15) 5Step-by-step explanation:
If three or more parallel lines are cut by two transversals, then they divide the transversals proportionally.Using the above we find the value of x
10.
x/48 = 30/25x/48 = 6/5x = 48*1.2x = 57.611.
x/ (49 - 28) = 36.4/28x/21 = 9.1/7x = 21*9.1/7x = 27.312.
(2x + 6)/36 = 52.5/60(x + 3)/18 = 7/8x + 3 = 18*7/8x + 3 = 15.75x = 12.7513.
(x - 3)/21 = (x - 1)/279(x - 3) = 7(x - 1)9x - 27 = 7x - 79x - 7x = 27 - 72x = 20x = 1014.
(2x + 5)/22 = (x + 10)/168(2x + 5) = 11(x + 10)16x + 40 = 11x + 11016x - 11x = 110 - 405x = 70x = 1415.
(7x - 11)/(4x - 2) = 20/(35 - 20)(7x - 11)/(4x - 2) = 4/33(7x - 11) = 4(4x - 2)21x - 33 = 16x - 821x - 16x = 33 - 85x = 25x = 5
