What is the total cost of a $12.60 item plus 7% sales tax?
Answers
Answer 1
Answer:
To take a percent, move the decimal point of the percent two places to the left. 7% = 0.07
Then multiply:
12.60 • 0.07 = 0.88
12.60 + 0.88 = 13.48
The total cost is: $13.48
Then multiply:
12.60 • 0.07 = 0.88
12.60 + 0.88 = 13.48
The total cost is: $13.48
Answer 2
Answer:
7% = 0.07
12.60 * 0.07 = 0.88
12.60+0.88 =13.48
$13.48
I hope this helps;)
12.60 * 0.07 = 0.88
12.60+0.88 =13.48
$13.48

We have to make an equation: a number increased by 10 is 114.
An equation is:
x + 10 = 114
x = 114 - 10
x = 104.
An equation is:
x + 10 = 114
x = 114 - 10
x = 104.

To find the value of x, and then find the angles of triangle RST, we first need to set up an equation equal to 180.
First, the equation = 180:
We have 31, x+4, and 3x+9.
What we can do is make an equation in which adds the angles to equal 180.
As so:
31 + x + 4 + 3x + 9 = 180
Combine like terms:
31 + x + 4 + 3x + 9 = 180
44 + x + 3x = 180
44 + 4x = 180
Now, we need to simplify this further by subtracting 44 from each side:
44 - 44 + 4x = 180 - 44
4x = 136
Next, to simplify this equation even further, we need to divide each side by 4 (Resulting in the x being alone on one side of the equation.)
4x / 4 = 136 / 4
x = 136 / 4
x = 34
Awesome! We now know that x = 34!
However, we are not completely finished with this problem. Let's continue.
To find the angles of S and T, we need to substitute 34 in for x:
S:
(x + 4)
(34 + 4)
38 degrees
T:
(3x + 9)
(3(34) + 9)
(102 + 9)
111 degrees
Amazing! We now can conclude all of the angles' measurements:
R = 31
S = 38
T = 111
Also, x = 34.
Hope I could help you out! If my math is wrong or it isn't the answer you were looking for, please let me know!
