12 because 12 is never wrong and 12 is an amazing number
Answer:(2,1/3)
Step-by-step explanation:
-x-3y=-3
2x+3y=5
_________First solve for x since y is 0. -3y+3y=0
1X = 2
1x/1= 2/1
X= 2
Now substitute your x answer into any equation to find y I used second equation
2x+3y= 5
2(2)+3y=5
4+3y=5
3y=5-4
3y=1
3y/3=1/3
Y=1/3
Answer:
0.86
Step-by-step explanation:
Its just multiplication
Answer:
Sales tax: $2.10
■ Cost/Price before ST: $30.00
■ Total Cost/Price including ST: $32.10
First convert the first equation to combine like terms. Then set your equations up as an addition problem. You want at least one of your variables (y) to be of opposite values so the will cancel out to leave you with just one variable (x). Plug in 1/3 for the x into one of the equations to solve for y. Then write as an ordered pair.
