Answer:
$70.2 (approximately)
Step-by-step explanation:
Cost per gallon is, $1.39/792
so, for 40,000 gallon,
$1.39×40,000/792
= $6950/99
≈ $70.2

Answer:
x = 1, y = -4
Step-by-step explanation:
7х + 2y = -1 ------ eq1
3х — 4y = 19 ------ eq2
multiply eq1 by 2
2 x (7х + 2y = -1)
14x + 4y = -2 -----eq3
by elimination, add equation 2 and 3
14x + 3x = 19-2
17x = 17 (divide both sides by 17)
x = 1 (answer)
substitute into eq1
7(1) + 2y = -1 (subtract 7 from both sides)
2y = -1 -7
2y = -8 (divide both sides by 2)
y = -8/2 = -4 (answer)
10+25+15 = 50 minutes
25 minutes for lifting weights
25/50 = 1/2
For 1. If two lines are parallel, the slopes are the same.
If two lines are perpendicular, the slopes are the opposite reciprocal, or is -1.
2. The answer is 3/2. Because in a perpendicular slope of a line, it has to be opposite sign and the reciprocal.
3.It is parallel.
because first we solve 6x-3y=8
We move the 6x to the other side, making it -6x
Now we have -3y=-6x+8
We use the y=Mx+b
-3y=-6x+8
Then we divide by -3
answer: y= 2x-8/3
now compare
y=2x+3
and
y=2x-8/3
With this we know it’s parallel because it’s the same slope but different y-intercept .

Answer:
60 units
Step-by-step explanation:
Ratio of the perimeter = ratio of sides
Sides are in the ratio:
6 : 24
1 : 4
Perimeter of the first triangle:
4+5+6 = 15
Perimeter of the second triangle:
4(15) = 60
