Answer:

-1.5

Step-by-step explanation:

-9=-3(x+2)+5x  (switching the sides of the formula can make it easier)

-3(x+2)+5x=-9

2x-6=-9

add 6 to both sides --->   2x-6+6=-9+6

simplify ----> 2x=-3

divide both sides by 2 --->  2x/2 = -3/2

simplify ---> x= -3/2

decimal form- -1.5

11. Determine if (-4, 6) is a solution for this system
atroni [7]
Yes the ordered pair is a solution because you put in the values from the solution into the equation so: 6= -4+10, which is true. and 2(-4) + 6 = -2

URGENT!!! PLEASE HELP
Molodets [167]

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

Harlene tosses two number cubes. If a sum of 8 or 12 comes up, she gets 9 points. If not, she loses 2 points. What is the expect
Amanda [17]
P(8 or 12) = 1/6
P(not 8 or 12 = 5/6
Let the expected points fro one roll be X.
E(X)=9\times\frac{1}{6}-2\times\frac{5}{6}=-\frac{1}{6}\ points
The answer is -(1/6) points.

Answer:

A) 5  3/10

B) 785 3/20

Step-by-step explanation:

Hope this helps <3

you find a common denominator and then simplify all fractions to that common denominator. then, you add them up!

2 1/5 + 3 1/10

5 can fit into 10 twice so it becomes...

2 2/10 + 3 1/10 which equals

<u>5 3/10</u>

472 2/5 + 312 3/4

5 times 4 is 20

472 8/20 + 312 15/20

there is a remainder of 3 for the fractions so you put it over 20.

<u>785 3/20</u>
