Answer:it’s 166.46
Step-by-step explanation:I did this in my school online
Answer:
166.5275
Step-by-step explanation:
i looked it up
x= -66/19
Multiply 2 on both sides:
2*(5x+6)/2=3(4x+12)*2
Simplify:
5x+6=24x+72
Subtract 6 from both sides:
5x+6-6=24x+72-6
Simplify:
5x=24x+66
Subtract 24x from both sides:
5x-24x=24x+66-24x
Simplify:
-19x=66
Divide both sides by -19
-19x/-19=66/-19
Simplify:
x= -66/19
Answer:
$20.43 is how much tip was
Step-by-step explanation:
27% >>> .27

Answer:
13
Step-by-step explanation:
(3 - 2i)(3 + 2i)
FOIL
first 3*3 = 9
outer 3*2i = 6i
inner -2i*3 = -6i
last -2i * 2i = -4i^2 = -4(-1) =4
Add together
9+6i-6i+4 = 13
6 + 5
-6 + 5
-6 + (-5)
Answer: 6+5
Step-by-step explanation:
y = 3x + 2
Answer:
y = -1/3x +6
Step-by-step explanation:
You want the equation of the line through (3, 5)perpendicular to the line y = 3x +2.
The given equation is in slope-intercept form. This lets us identify its slope as 3.
y = mx + b . . . . . . line with slope m and y-intercept b
y = 3x +2 . . . . . . . line with slope 3 and y-intercept 2
The perpendicular line will have a slope that is the opposite reciprocal of this:
m = -1/3 . . . . slope of the perpendicular line
The equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The equation for a line with slope -1/3 through point (3, 5) is ...
y -5 = -1/3(x -3)
Solving for y gives us ...
y = -1/3x +1 +5 . . . . . eliminate parentheses, add 5
y = -1/3x +6 . . . . . equation of the desired line

Answer:
x= 36 km
Step-by-step explanation:
Vince went on a 3 day hiking trip. Each day, he walked 3/4 the distance that he walked the day before. He walked 83.25 kilometers total in the trip. How far did Vince walk on the 1st day of the trip?
Assume vince walked x km on the first day .
The following equation can be formed
x + 3/4 x + (3/4)^2 x = 83.25
x + 0.75x + 0.5625x = 83.25
Add the like terms
2.3125x = 83.25
Divide both sides by 2.3125
x = 36 km.
