sweet [91]3 years ago
7 0

Answer:

The answer is A (-3,4,6).

Step-by-step explanation:

1 Solve for z in -3x-4y+z=-1


z=3x-1+4y



2 Substitute z=3x-1+4y into 2x+y-z=-8


-x-3y+1=-8



3 Substitute z=3x-1+4y into x+8y-z=23


-2x+4y+1=23


4 Solve for x in -x-3y+1=-8


x=-3y+9



5 Substitute x=-3y+9 into z=3x-1+4y


z=-5y+26



6 Substitute x=-3y+9 into -2x+4y+1=23


10y-17=23



7 Solve for y in 10y-17=23


y=4



8 Substitute y=4 into z=-5y+26


z=6



9 Substitute y=4 into x=-3y+9


x=-3



10 Therefore,


x=-3


y=4

z=6

Hello!

Tangent lines have only one point on the circle, meaning they form straight angles with the edge of the circle. The radius goes from the center of the circle to the point where the tangent line is on circle, creating a right angle.

there are 24 marbles in a bag: 2/16 of the marbles are red, 1/8 of the marbles are blue, 1/4 of the marbles are yellow, 1/3 of t
Roman55 [17]

Answer: 3 red marbles, 3 blue marbles, 6 yellow marbles, 8 black marbles, 4 silver marbles

Step-by-step explanation:

I know these are the correct number of marbles because I set up these numbers as fractions and solved for x.

For examples, 2/16 of the marbles are red. 2/16=x/24

You would do this because we are trying to find the number of marbles that are red out of the 24 marbles.

Next, we would do 24 divided by 16= 1.5 Then 1.5 times 2=3

You would follow this rule for each fraction of marbles in order to find the true number of marbles out of 24.

Solve the linear equation 2x+2/4=189.5
seraphim [82]
Change 2/4 to 1/2
<span><span>2x+<span>1/2</span>=189.5</span></span>
Subtract <span>1/2</span> from both sides(1/2 = .5)
2x=189
Divide both sides by <span>2</span>
2x/2 = x
189/2= 94.5
x=94.5
