Match each equation on the left with its simplified version from the choices on the right. Do not solve. (not all the choices will be used.) -2(3x-10)=15 __ A. -6x+2=15 ⅕(30x-10)=15 __ B. 6x-2 = 15 3(2x-10)=15 __ C. 6x+2=15 -⅕(30x-10)=15 __ D. 6x-30 = 15 E. -6x+20=15 F. -6x-20 = 15

Step-by-step explanation:

Given the expression -2(3x-10)=15, we are to find the equivalent expression;

Open the parenthesis using the distributive law;

-2(3x-10)=15

-2(3x) -2 (-10) = 15

-6x + 20 = 15

Hence the simplified version of the expression is -6x + 20 = 15

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
