<span>-4x + y = -25        y = 4x - 25

-6x - 6y = 0            </span>
 
-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5

y = 4(5) - 25
y = 20 - 25
y = -5

(5, -5)

The sum of three numbers is 51 . the second number is 2 times the third. the third number is 9 more than the first. what are the
hammer [34]
X+y+z=51

y=2z
z=9+x

subsitute those

x+2z+9+x=51
x+2(9+x)+9+x=51
x+18+2x+9+x=51
4x+27=51
minus 27 both sides
4x=24
divide by 4
x=6

sub back

z=9+x
z=9+6
z=15

y=2z
y=2(15)
y=30

the numbers are

vRichard has a red card (R) and a black card (B). He picks a card randomly from the pair and then rolls a six-sided die. The sam
Alik [6]

The Sample space for three cards is

S=\left\{\left(B,1\right),\left(R,1\right),\left(G,1\right),\left(B,2\right),\left(R,2\right),\left(G,2\right),\left(B,3\right),\left(R,3\right),\left(G,3\right),\left(B,4\right),\left(R,4\right),\left(G,4\right)\left(B,5\right),\left(R,5\right),\left(G,5\right),\left(B,6\right),\left(R,6\right),\left(G,6\right) \right \}

There are two cards red(R) and black(B) and a six-sided die.

The event is one card is picked randomly and then rolls the die.

So, the Sample space is as follows.

S=\left\{\left(B,1\right),\left(R,1\right),\left(B,2\right),\left(R,2\right),\left(B,3\right),\left(R,3\right),\left(B,4\right),\left(R,4\right),\left(B,5\right),\left(R,5\right),\left(B,6\right),\left(R,6\right) \right \}

<h3>Find Sample space if there are three cards.</h3>

Consider there were three cards red(R), black(B) and green(G) a six-sided die.

The event is one card is picked randomly and then rolls the die.

So, the sample space will be as follows,

S=\left\{\left(B,1\right),\left(R,1\right),\left(G,1\right),\left(B,2\right),\left(R,2\right),\left(G,2\right),\left(B,3\right),\left(R,3\right),\left(G,3\right),\left(B,4\right),\left(R,4\right),\left(G,4\right)\left(B,5\right),\left(R,5\right),\left(G,5\right)\left(B,6\right),\left(R,6\right),\left(G,6\right) \right \}.

Select two ratios that are equivalent to 2 : 9.
White raven [17]

Answer:

B & C

Step-by-step explanation:

2:9 can also be written as 2/9

A. 9:2 is just the reciprocal of 2:9 so it is not equivalent to it

B. 18:81 is 2×9:9×9 meaning that is equivalent to 2:9

C: 12:54 is 2×6: 9×6 so it is equivalent to 2:9

Since the two correct answers have already been found, I don't need to explain more.

Hope this helped!!!
