6x-8
2(3x-5) use the distributive property to get 6x-10
6x-10 is not the same as 6x-8 so the two equations are not equivalent.
Answer:
7/2 or 3.5
Step-by-step explanation:
The y-axis represents the cost is dollars. The x-axis is the amount of gasoline in gallons. To find the cost in dollars per gallon, choose a point on the graph, and divide the dollars (y-coordinate) by the gallons (x-coordinate).
cost = (21/4) / (3/2)
cost = 21/4 * 2/3
cost = 42/12
cost = 7/2 = 3.5
Answer:
Step-by-step explanation:
A)
This is the 30% discount:
$39.99 x .30 = $11.997; The discount is $11.997
Price of headphones after the discount:
$39.99 - $11.997 = $27.99
Now we need to calculate the 6% sales tax on the discounted price.
$27.99 x .06 = $1.68 (rounded off)
Dalton paid $1.68 in sales tax on the discounted price.
B)
The total price Dalton paid for the headphones will be the discounted price plus the sales tax.
$27.99 + $1.68 = $29.67
Total price Dalton paid: $29.67
