Answer:

Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

How do you solve this math problem-2(x+3y)=18

ss7ja [257]

Greetings!

Solve for x.
$-2(x+3y)=18$
Distribute the Parenthesis. How? Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
$(-2)*x+(-2)*3y=18$
$-2x-6y=18$
Add 6y to both sides.
$(-2x-6y)+6y=(18)+6y$
$-2x=18+6y$
Divide both sides by -2.
$(-2x)/-2=(18+6y)/-2$
The Answer Is:
$x=-9-3y$
$x=-3y-9$

Hope this helps.

19. You roll two standard number cubes. What is the probability that the sum is odd, given than one of the number cubes shows a

In-s [12.5K]

6 numbers per cube

if one is a 1, then the other one has to be a 2, 4 or 6 to be an odd sum

1+2=3, 1+4=5,1+6=7

since there are 3 numbers you can get that would be a 3/6 ( reduce to 1/2) probability

so 1/2 probability

Two vertical angles will always equal 180 degrees

Margarita [4]

Answer:

Hi there!

Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees.
