Answer:
x=11/2
Step-by-step explanation:
1/2x-4=7+1/6x
1/2x-1/6x=7+4
6*1/2x-1/6*6=11 As 6 is the Lcm and we have to multiply it to the fractions.
3x-x=11 As 6 divided by 2 is 3 and 3 multiplied by x is 3x.
2x=11
x=11/2 OR 5 1/2
Answer:
4y = 6x + 40
Step-by-step explanation:
The general equation of a straight line is y = mx + b
m is the slope and b is the y-intercept
let us write both equations in this form;
we have this as;
6y = -4x + 1
y = -4x/6 + 1/6
and;
2x + 3y = 18
3y = -2x + 18
y = -2x/3 + 6
So firstly we want to find an equation that is perpendicular to the first
When two lines are perpendicular, their slopes has a product of -1
The slope of the first line is -4/6
let the slope of the line we want be m
As per they are perpendicular;
-4/6 * m = -1
-4m/6 = -1
-4m = -6
m = 6/4
So now, we want the y-intercept greater than that of the second equation which is a y-intercept of 6
we can choose 10
and we have the equation as:
y = 6x/4 + 10
multiply through by 4
4y = 6x + 40
Answer:
31 men are enrolled
Step-by-step explanation:
1 to 5
Divide 186 by 6. Then you would get 31 since that is the unit rate.
To check, multiply 31 by 5 and you would get 155, add 155 with 31, you would get 186. I don't really know how to explain it but thats my answer.
