This answer maybe long, but it includes all the essential steps to make it easy
This problem shows that the fraction of the time worked by three individuals need to be = to one person working full time.
It just means that the fractions need to add up to one. Since we got to know that one person works 1/2 the time on the project and the other works 1/3 of the time, let us use a variable to represent the amount of time the last person needs to work to have a total of 1.
This is quite easy:
variable = t(representative of the last person)
step 1: 1=1/2+1/3+t
step 2: keep the variable alone at one side
1-1/2-1/3=t
this step on a calculator will be easy, but dont have a calculator? Thats fine!
Lets have a common denominator
2 and 3 can be 6
1/1*(6/6)-1/2*(3/3)-1/3*(2/2)=t
6/6-3/6-2/6=t
step 3: just subtracts and get the answer
1/6=t
In conclusion, the third person must be working 1/6 the time on the project
Step-by-step explanation:
x = 3 and y = 5.
1: 2xy
2 x 3 x 5
=30
2: 6y divided by x
6 x 5 / 3
30/3
=10
3:4y- x
4 x 5 -3
20-3
=17
4:Y(to the power of two) -7x +2
5^2 -7 x 3 + 2
25-7x3+2
25-21+2
25-19
=6
7y^2 - y^2 = 6y^2
hope it helps
Answer:
The slope of line A equals one-half. The slope of line B equals 2.
Step-by-step explanation:
The equation of Line A is given by : 
........... (1)
The equation of Line B is given by : y = 2x - 3 ............. (2)
Those two equations are in slope-intercept form i.e. y = mx + c, where m is the slope of the line.
Now, the slope of line A equals one-half. The slope of line B equals 2.
Therefore, option 1 will be correct. (Answer)
