Divide 380 among A, B and C in such a way that B gets 30 more than A and C gets 20 more than B. ​
Readme [11.4K]

Answer:

A = 100 B = 130 C = 150

Step-by-step explanation:

Translated into a system of equations:

A+B+C = 380

B = A+30

C = B + 20

So we find B from the last one:

B = C-20

Plug it in the second one:

C-20 = A+30

A = C-50

Plug it in the first:

C-50 + C-20 + C = 380

3C - 70 = 380

3C = 450

C=150

A = C - 50 = 150 - 50 = 100

B = C - 20 = 150 - 20 = 130

What numbers multiply to equal -9 but add up to 12?
Elan Coil [88]
I don't think this is possible.

The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3

And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0

Sorry but there is not an answer. :(

What is the equation has intercepts at x(1, 0, 0), y(0, -1,0), and z(0, 0, 2)
bulgar [2K]

In intercept form, the plane that has these intercepts is ...

... x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1

... x/1 + y/(-1) + z/2 = 1

... 2x -2y +z = 2 . . . . . in standard form
