2x-15y=6---->1
x-6y=-1
x=-1+6y----->2
use substitution
substitute 2 in 1
2(-1+6y)-15y=6
-2+12y-15y=6
-3y=6+2
-3y=8
y=-8/3
x=1+6(-8/3)
x=1+(-16)
x=-15

Answer: Lizard=5, Tree=6, Snowman=3, Snowflake=4.
Step-by-step explanation: First, I look at the bottom row and I do 24 divided by 4 to find out the tree is 6.
Then I look at the third row, and I can see a snowman and a snowflake equals 7.
Now I look at the 2nd column, so with the snowman equaling 6, and a snowflake and a snowman equaling 7 add those together to 13, then do 18 minus 13 and the lizard thing is 5.
Now with the 1st column the 2 trees equal 12, and the lizard equals 5, so add those together (17) and do 20-17 so the snowman equals 3.
Now I look at the 2nd column again so first the lizard is 5 + the snowman (3) + the tree (6) and those together is 14, now do 18-14 so the snowflake is 4.
Answer:
Lizard=5
Tree=6
Snowman=3
Snowflake=4
Step-by-step explanation:
Start by dividing the last horizontal row, which is 24, by 4. You get 6. Then you go to the third vertical line and fill in for the trees with 6 and you get a total of 12. Then subtract 12 from 18, because that’s the total of the third vertical line, and you get 6. Just divide 6 by 2 for the snowmen and then it is pretty intuitive if you follow the pattern I listed above.

How to find the slope using the rising over run and the slope formula
Answer: Divide the rise by the run to calculate the slope, which helps you to find the rise and run between other points on the same line. In the example, x divided by y calculates a slope of x/y . A positive slope means the line goes up from left to right, but a negative slope means it goes down.

The charity gala will cost $270 if it has 15 attendees. How many attendees can there be, at most, if the budget for the charity gala is $558? Assume the relationship is directly proportional.
Answer:
31
Step-by-step explanation:
For 15 people the charity gala costs $270, so for 1 person it costs 270÷15 = 18.So, $18 for each person, now you have a budget of $558, therefore you divide 558 by 18 = 31This concludes that the total number of attendees that can be at the gala is 31.In each figure below, find m∠1 and m∠2 if a║b.
