3(-1) + 5y = 17
add 3 to both sides
5y=20
divide by 5
y=4
Answer:
Step-by-step explanation:
y = 3x + 15 represents a straight line whose y-intercept is (0, 15) and which has the steep positive slope m = 3.
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.
