Answer:
(2, 4)
Step-by-step explanation:
To solve this system, the easiest way would be to use the substitution method. You can simply plug in, or substitute the value of y from the second equation, which is -x + 6, into the first equation. So you would get:
-x + 6 = 3x - 2
6 = 4x - 2
8 = 4x
2 = x.
To find y, just substitute the value of x, which is 2, into either equation:
y = 3(2) - 2
y = 6 -2
y = 4.
Make sure you write your answer as an ordered pair! So, the final answer is (2, 4). Hope that helped! :)
Multiply both sides by 3 to cancel out the 3 in the denominator of the left side of the equal sign. You get:
x + 4 = 18
Now subtract 4 from both sides to get variables one side, constants on the other.
x = 18 - 4
x = 14
Your answer is x = 14
None of those answers are correct sadly.
Answer:
$24.36 for the bookbag if they tax the original price
$23.97 if they tax the sales price
$31.10 for the necklace if they tax the original price
$30.60 if they tax the sales price
So an overall of $55.46 was spent for a taxing of the original price and an overall of $54.57 was spent for the taxing of the sales price.
Step-by-step explanation:
20% of $28.00 is $6.60, subtract $6.60 from $28.00 and you'll get $22.40.
7% of $28.00 is $1.96, add $1.96 to $22.40 and you'll get $24.36 (for taxing of the original price). If you want the taxing of the sales price then you'd do 7% of 22.40 which is $1.57, add that to $22.40 and you get $23.97
Then you do the same for the necklace:
20% of $35.75 is $7.15, subtract $7.15 from $35.75 and you'll get $28.60.
7% of $35.75 is $2.50, add $2.50 to $28.60 and you'll get $31.10 (for taxing of the original price). If you want the taxing of the sales price then you'd do 7% of 28.60 which is $2.00, add that to $28.60 and you get $30.60
Add the final numbers and you'll get your overall.
Hope this helps
