This is crazy. If I'm reading this right (I'm not sure why there are spaces put in between some of those numbers like there is), I'm getting that the answer is
-1079.242293. But again, those spaces are throwing me off. I eliminated the spaces between the numbers while I was performing the operations in order.
x=13 because you put all of them in an equation and set them equal to 180 bc that is how many degrees are in a triangle so it would be 6x+19+5x-15+3x-6=180 and then you solve the equation so it would be 14x-2=180 then you would add to to both side which would cancel out on the left and make 182 on the right then divide 182 by 14 and you get 13.
System of equations:
x + y = 23
x - y = 7
Add them together
2x = 30
x = 15
Now plug 15 into one of the equations:
15 + y = 23
y = 8
your two numbers are 15 and 8
Answer:
The price for one cone before tax is $2.26.
Step-by-step explanation:
The tax for each cone is $.17
Ronnie buys six cones. The total tax for the cones is 6 X $.17 = $1.02
Next, we subtract the total taxes from the total price $14.58 - $1.02 = $13.56
So Ronnie owed $13.56 for the six cones BEFORE taxes. We takes this amount and divide it by six to get the cost for one cone.
$13.56 / 6 = $2.26 per cone.
Check our work
Purchase one cone for $2.26 plus $.17 cents tax = $2.43 total cost per cone.
6 cones at $2.43 each would be 6 X $2.43 = $14.58.
This matches the total bill from the story problem.
Answer:
6x
Step-by-step explanation:
BODMAS
8x + x = 9x
9x - 3x = 6x
