64 and 24 can be combined so if you were going to simplify this your answer would be 88 - 82g.
You would add 64 + 24 = 88 and since you can't subtract 88 and 82 because they both don't have a variable your answer would be 88 - 82g.
Hope this Helps!!
Add 6 to both sides so that you can get the variable by itself
I don't have the grid, so you'll have to actually plot the points and draw the line yourself. But I can help you calculate some points to plot.
Let's start off with 0 gallons of shampoo. So 0 times $40 = $0 and we have a fixed cost of $400. So the result is $0 + $400 = $400. And there's your first point (0, 400).
Now let's do 1 gallon of shampoo. 1 times $40 = $40 and we have to add the fixed cost of $400, so the result is $40 + $400 = $440. And your second point is (1,440).
In fact, we can create the function
c(x) = 40*x + 400
to express the cost for any amount of shampoo. So let's calculate 3 more points
c(2) = 40*x + 400 = 40 * 2 + 400 = 80 + 400 = 480
c(3) = 40*x + 400 = 40 * 3 + 400 = 120 + 400 = 520
c(4) = 40*x + 400 = 40 * 4 + 400 = 160 + 400 = 560
So 3 more points to plot are (2,480), (3,520), and (4,560).
And you've gotten your 5 points. They are (0,400), (1, 440), (2, 480), (3, 520), and (4, 560). Just plot them on your chart and draw a straight line through all 5 of them. And they will be in a straight line, if they're not, then you plotted them incorrectly.
Answer:
n = 13
Step-by-step explanation:
374 = 11(2n+8)
Expand the right side
374 = 11* 2n + 11 * 8
374 = 22n + 88
Subtract 88 from both sides
374 - 88 = 22n
286 = 22n
divide both sides by 22
n = 13
