Answer:
the total weights in tons is 18
Step-by-step explanation:
The computation of the total weights in tons is shown below:
The weight of 8 cars would be
= 4,500 pounds × 8 cars
= 36,000 pounds
Now as we know that 1 ton = 2,000 pounds
So for 8 trucks it would be
= 36,000 pounds ÷ 2,000 pounds
= 18 tons
Hence, the total weights in tons is 18
179÷10=17.9
Hope that is right. Not sure what partitioning is lol
(0,-2)(- 2,1)....I found 2 whole number sets of points
slope = (y2 - y1) / (x2 - x1)
(0,-2)....x1 = 0 and y1 = -2
(-2,1)...x2 = -2 and y2 = 1
now we sub
slope = (1 - (-2) / (-2 - 0) = (1 + 2) / -2 = -3/2...this is ur slope
the y intercept is where the line cross the y axis...and it is -2 or (0,-2)...this is one way to find it....there is another way that I will show u later in the problem
y = mx + b
slope(m) = -3/2
u can use either of ur points (-2,1)...x = -2 and y = 1
now sub and find b, the y intercept
1 = -3/2(-2) + b
1 = 3 + b
1 - 3 = b
-2 = b .......this is the other way to find the y int.
so ur equation is : y = -3/2x - 2.....and in y = mx + b form, the slope is in the m position and the y int is in the b position
to find the x intercept, take ur equation, sub in 0 for y and solve for x...or u could look at ur graph and see where the line crosses the x axis...but in this problem that would not be easy because it is not a whole number
y = -3/2x - 2
0 = -3/2x - 2
3/2x = -2
x = -2 / (3/2)
x = -2 * 2/3
x = -4/3 or (-4/3,0)
u could also find the y int by subbing in 0 for x and solving for y
Answer is 5/2 i took that quiz too
In this case, it's clear that 5 is half of ten, therefore, you have to divide the first equation in half, giving you 5x42= 210. If it was something such as 20x24, you just work the answer from the multiple of ten.
Hope this helpsn
