First know how many pounds are in a ton
there are 2000 pounds in a ton
so simply divide
7000/2000=3.5
So there are 3.5 tons of brick on the truck
Answer:
y = 360x+200
Step-by-step explanation:
We will use the concept of finding the equation of a line using two coordinates (x1,y1) and (x2,y2)
If after 3 months, ethan has 560 dollars in his savings, and after 6 months, he has 920 dollars, this can be represented as coordinate points (3,560) and (6,920)
The equation of a line in point slope form is expressed as;
y = mx+c
m is the slope = ∆y/∆x = 920-560/6-3
m = 360/3
m = 120
Get the intercept;
Substitute m = 120 and any of the points to get c, using the point (3,560)
x = 3, y = 560
560 = 120(3)+c
560 = 360+c
c = 560-360
c = 200
Get the required equation by substituting m and c into y = MX+c
y = 360x+200
Answer:
Basic fee = $14.95
1.5 dollars per quart of oil
Step-by-step explanation:
Each customer is charged a fee x (in dollars) for the oil change, plus y dollars per quart of oil used.
The oil change for the car that requires 5 quart of oil costs $22.45.
The oil change for the car that requires 7 quarts of oil costs $25.45.
Both equation having x
so make it equal and solve for y
Add 7y on both sides
subtract 22.45 from both sides
now plug in 1.5 for y and solve for x

Step-by-step explanation:
I think that it is D as if X = Us $ and the function h(x) is the euros whatever number you put in as x whatever it equals is euros
Hope this makes sense
