Answer:

X = 4

Step-by-step explanation:

you just gotta subtract 1 from both sides in order to find what x equals. and from there you subtract x from both sides, any letter has an invisible 1 in front, so then you divide 2 from both sides. and you get x = 4

To change knots per hour, use the expression 1.15k, where k is the speed in in knots per hour. A plane is flying at 300 knots pe
Free_Kalibri [48]
1.15(300).
Substitute k for 300, since the plane is flying 300 knots per hour, and k=knots per hour.

1.15(300)=345 miles per hour
After multiplying, 300 by 1.15, you get 345 miles per hour. This is the speed of the plane from Knots to MPH (Miles Per Hour).

Write the equation of the line perpendicular to the line x - 3y = 9 and passing through the point (3,5).
PilotLPTM [1.2K]
Here is a sample problem
has to be perpendicular to y=(4/9)*x-2 and pass through 4,3,


y-b=m(x-a)
slope of -9/4 is perpendicular to slope of 4/9, as y=4/9x-2 has slope 4/9. Our point is (4,3) therefore.
y-3=-9/4*(x-4)
y-3=-9/4x+9
y=-9/4x+9+3
y=-9/4x+12

The sum of three numbers is 69. If the second number is equal to the first diminished by 8, and the third number is 5 times the
bonufazy [111]
X = first number
x - 8 = 2nd number
5x = 3rd number

x + x - 8 + 5x = 69
7x - 8 = 69 <=== this is the equation u would use

7x - 8 = 69
7x = 69 + 8
7x = 77
x = 11

1st number = 11
2nd number : x - 8 = 11 - 8 = 3
3rd number : 5x = 5(11) = 55
