4 0

Answer:

  y = 4/3

Step-by-step explanation:

The two equations can be added to eliminate x:

  (0.1x +0.5y) + (-0.1x -0.2y) + (1.2) +(-0.8)

  0.3y = 0.4 . . . . . simplify

Divide by the coefficient of y to find y:

  y = 0.4/0.3

  y = 4/3

Determine whether y = 2x - 3 is a linear equation. If so, write the equation in<br> standard form.
beks73 [17]

Answer:

yes, y=2x-3 is linear

2x - y = 3  Standard Form

Step-by-step explanation:

since both the 'x' and 'y' variables have one as their exponents then this represents a linear equation

standard form: Ax + By = C

y = 2x - 3

subtract 2x from each side to get:

-2x + y = -3

divide each term by -1 to get (this is done so the leading coefficient is not negative)

2x - y = 3  Standard Form

Can someone plz help me
Illusion [34]
First rectangle:
Has 3 cubes in each 5 layers, and imagine it, so we have all dimension needed which is:
l=3 unit
w=1 unit
h=5 unit.
V=l×w×h
V=3×1×5
V=15 cubic inches.

Second rectangular:
Doing the same like that to get:
l=5 unit
w=1 unit
h=3 unit
V=15 cubic inches. As a result, there are no prism that are greater to each other, which mean that they have the same volume of 15 cubic inches. Hope it help!
