well, the order is $159, so say that's the 100%, we know the delivery charge was 10 bucks.
Answer:
C=15
Step-by-step explanation:
Equation: (7c-7)+(6c-8)=180
180 because a STRAIGHT LINE is 180degrees
Then you do 'math'
(7c+6c)-15=180
13c=195
c=15
The value of x that makes ABC~ RTS. is 12
<h3>How to determine the value of x?</h3>
From the figure, we have the following equivalent ratio:
2x + 6 : 40 = 36 : 48
Express as fraction
(2x + 6)/40 = 36/48
Multiply both sides by 40
2x + 6 = 30
Subtract 6 from both sides
2x = 24
Divide both sides by 2
x = 12
Hence, the value of x is 12

Answer:
Step-by-step explanation:
Next time, please be sure to share the possible answer choices. Also, please use " ^ " to indicate exponentiation: x^2 + (2/3)x.
Let's actually "complete the square" here:
Starting with x^2 + (2/3)x, identify the coefficient of the x term (it is 2/3).
Take half of that, which results in 2/6, or 1/3.
Square this result, obtaining (1/3)^2 = 1/9.
Add to, and then subtract from, this square:
x^2 + (2/3)x + 1/9 - 1/9
Rewrite x^2 + (2/3)x + 1/9 as the square of a binomial:
(x + 1/3)^2 - 1/9
In review: add 1/9 to, and then subtract 1/9 from, x^2 + (2/3)x
