Answer:
1331 feet3
Step-by-step explanation:
3a+b+c
The perimeter is two times one side (to account for the opposite) and two times the adjacent side. So if the sides would be x and y, the perimeter would be 2*x + 2*y.
So, knowing that the sum is 16a+8b-6c, if we subtract the given side 5a+3b-4c from this, what remains is two times the "other" side:
16a+8b-6c - 2*(5a+3b-4c) =
16a+8b-6c -10a-6b+8c =
6a+2b+2c
half of that is
(6a+2b+2c)/2 = 3a+b+c
$60 ÷ $15 = 4
$9 × 4 = $36
he saved $36 when he earned $60
Answer:
Carlos bought 80 feet of wire for $17.60.
Then the price for 1 feet of wire is 17.6/80 = 0.22
=> 30 feet of wire would cost: 30 x 0.22 = 6.6
Hope this helps!

Answer:
Step-by-step explanation:
Compare any two points on same horizontal line.
<u>The easy one is:</u>
<u>Since g(x) = f(kx), substitute the x- coordinates to find the value of k:</u>
- - 1 = k*(-3)
- k = - 1/ - 3
- k = 1/3
Correct choice is B
